A common side effect of increased engine power is increased fuel consumption. Remarkably, engine designers have been largely up to the task of creating ever more fuel ef ficient engines, techniques employed have included electronic fuel injection, variable valve timing, improved turbo charger designs, direct injection and hybrid propulsion systems. The overriding goal though is to have the best of both, a low mass vehicle structure meeting all safety expectations and a fuel ef ficient powertrain.Manufactures have explored new processing techniques and materials to increase vehicle safety while at the same time minimizing the mass of the vehicle. Taylor welded blanks allow utilizing two or more different thicknesses of steel in the same structural stamping, with the goal of placing additional steel only where it is needed. The hydroforming process, forming tubes by harnessing the force of internal fluid pressure, allows manufacturers to utilize complex variable sections and take advantage of stain hardening. Meanwhile alternative material utilization is also increasing, Ultra high strength steel (UHSS) and Advanced high strength steel (AHSS) combined are the most common of these materials. However alternative metals such have aluminum and magnesium are also becoming more prevalent. Utilizing these materials presents their own unique challenges however. AHSS is still somewhat dif ficult to acquire in Chinaand comes with a high cost of processing and initial capital investment. The use of aluminum and magnesium is problematic due to material cost as well as joining and galvanic corrosion dif ficulties.Figure 1: Data from Frost & Sullivan shows an ongoing trend in the automotive industry toward advanced steels and alternative materials as a means to reduced vehicle weight. Henkel chemical based products, structural adhesive and structural foam offer new tools to the automotive body engineer. These products help improve the ef ficiency of the metal structure and at the same time promote the use of multimetal assemblies. Structural adhesive and structural foam are both generally applied in the body shop. Structural adhesive is applied along the flange lines as a liquid prior to welding the sections together. Structural foam on the other hand is a solid part either a pressure sensitive tacky sheet cut to shape or a designed three dimensional part that can be welded, pinned or clipped into the assembly. Both materials then react in the elevated temperatures of the paint shop ovens, the adhesive cross links and forms a tough bond between the two adjacent panels. Whereas the Terocore expands bridging a necessary gap in assembly before cross linking and bonding to mating surfaces of the vehicle structure.The primary purpose of both structural adhesive and structural foam is to improve the ef ficiency of the vehicle structure. A typical automotive section or assembly is composed of several components, usually steel stampings joined by the use of spot welding. As the structure is loaded the spot welded joint is responsible for holding these componentstogether and transferring energy from one component to the next. The stress however is concentrated around the point of contact the spot weld, creating an uneven stress distribution along the flange. Structural adhesive aims to improve the ef ficiency of this joint, as illustrated in Figure 2A, by utilizing the entire flange surface area to distribute stress, thereby prolonging joint failure. In very similar fashion point loading or geometrical changes in the section necessitated by vehicle design, including holes, bends and joints create stress concentrations in the section components. Structural foam can be deployed locally in these locations, shown in Figure 2B, to transfer energy between the components to improve the ef ficiency of the larger open section.Figure 2: a) Increased energy absorption of lap shear test specimen by combination of spot welding and adhesive bonding [5] and b) elimination of local buckling due to broadening of the deformation area [6]Using structural adhesive to improve the joint ef ficency, can be further illustrated by observing the effects of a box beam three point bend test. Figure 3, shows a section representative of an automotive b-pillar that was impacted at a 45° angle, representative of a side impact in which both vehicles are in motion. Inspection of the test sample prepared using traditional spot welding showed a large distortion and separation of the spot weld flange. Whereas the test sample prepared with impact optimized adhesive showed no such separation. Maintaining integrity of the flange results in increased energy absorption capacity, after 160 mm of displacement the spot welded beam absorbed 1.962 kJ whereas the beamwith impact optimized adhesive showed 2.630 kJ, a signi ficant improvement. The source of this large difference was not merely the energy required to bend the adhesive, but it was primarily the result of the improved ef ficiency of the joint, which allowed the assembly to work more effectively.Figure 3: Weld flange separation and energy absorption at 130 mm de flection for box beam joined by spot welding only and joined by bonding using an impact resistant adhesive (no spot welding applied)A crash event involves one or more vehicles in motion, the kinetic energyof this motion must be absorbed by the vehicle structure in order to bring the vehicles to rest. Generally speaking it is preferable for the structural members comprising the passenger compartment to absorb this energy with little deformation. Increased deformation of this structure increases the risk of occupant injuries resulting from impacting the interior surface as it intrudes upon the passenger space. The most signi ficant result of the improved ef ficiency resulting from structural adhesive use becomes evident when comparing beam deformation at a given level of energy absorption. The energy absorption chart in Figure 4, for instance has a line drawn at 2.0 kJ of energy, the spot welded beam deforms 139 mm while beam assembled with impact resistant adhesive only deforms 102 mm. This reduction of deformation would translate to a reduction of intrusion and corresponding increase in survival space of 37 mm.Figure 4: Energy absorption and d isplacement of steel box beams under 45° impact depending on joining method: Spot welding versus bonding withstiffening adhesive (no spot welding applied) versus bonding with impact resistant adhesive (no spot welding applied)A similar study was conducted on beams utilizing Terocore structural foam. The box beam sections were prepared with a layer of Terocore structural foam applied between the outer panel and the reinforcement. Evident in Figure 5 is that the Terocore beam absorbed much more energy throughout the deformation than the standard construction beam. The increase energy absorption rate allows the Terocore beam to absorb 2.0 kJ in 60 mm less de flection than the standard construction beam a signi ficant increase in survival space.Figure 5: E nergy absorption and displacement of steel box beams under 45° impact: spot welding only versus reinforcement with structural foam plus spot weldingFigure 6: Weld flange separation and energy absorption at 130 mm de flection for box beam joined by spot welding only and joined by bonding using an impact resistant adhesive (no spot welding applied) Analagous to the adhesively bonded beams the beams using Terocore absorb more energy at a given de flection than does the traditional beam. The Terocore beam absorbed 4.03 kJ at 130 mm of de flection compared to only 1963for the standard construction beam, an increase of over two times.The improvement with Terocore demonstrated here is in line with prior experiments conducted by Mazda. In a paper entitled ‘Devel opment of a technique to strengthen body frame with structural foam’ it was shown that structural foam when applied between the inner and reinforcement ofa b-pillar increased the bending moment by more than 50%. The authors explain that the structural foam reinforcement prevents the onset of local deformation in the steel panels, allowing the assembly to maintain its shape stability and function throughout the impact event as it was designed. This concept of using Terocore as an enabling technology to improve the ef ficiency of the existing structure is further enhanced by examination of the energy absorption contribution of each component of the assembly. Figure 7 shows the energy absorbed by the components both before and after the application of Terocore. Notice that the top red sliver on the columns with Terocore, is the contribution of the Terocore itself. The Terocore absorbs less than 5% of the total energy of the bending event. If we look at the contribution of the reinforcement however, we see that it nearly doubles from the standard beam to the Terocore beam. The Terocore enables this steel reinforcement to work much more ef ficiently.Figure 7: Increase of energy absorption of reinforcement panel and eliminated local buckling by reinforcement using structural foam due to energy transfer between outer skin and reinforcement panel [6]Let’s go back now and reexamine the first set of Terocore reinforced box beams shown in Figure 6. You will notice that like the spot welded only beams, it still shows separation of the flange line. The Terocore applied between the outer and the reinforcement has increased the ef ficiency of the large open section of the beams, but has done nothing to improve the joint ef ficiency. Even with the improved section provided by structuralfoam, remaining ef ficiency can still be realized by utilizing structural adhesive in the spot welded joints.The second area where Henkel structural adhesive and structural foam helps to expand the automotive engineer’s toolbox and of fer additional methods to improve crash performance while at the same time maintaining a low mass, is by enabling the use of multi-metal assemblies.A dif ficulty which arises when utilizing multiple metals in an assembly is galvanic corrosion. Galvanic corrosion occurs when two different metals such as aluminum and steel are in contact in the presence of a corrosive substance. Electrons from the less noble material flow to the more noble metal and instigate corrosion. In order to prevent the flow of electrons from one metal to the other, one must place an insulating material in between, structural adhesive and structural foam are two such materials that are suitable for this task.Utilizing multiple metals in an assembly is especially appealing to an automotive designer, as it allows the selection of the best suited material from a wide basket of materials. A door for instance could utilize a light weight smooth finish aluminum stamping, applied to a ultra light weight magnesium structure that is locally reinforced at the hinges with steel plates, such a closure assembly is shown in Figure 8. Dif ficulties however arise when attempting to join such an assembly. In addition to the problem of galvanic corrosion, welding of these dissimilar metals is not feasible. Mechanical fasteners meanwhile somewhat defeat the purpose as it adds considerable mass, and like spot welding still creates point loadsalong the joint, with the exception that now a hole is needed in the substrates elevating stress maxima even further. Adhesive bonding eliminates these concerns, the continuous film between these dissimilar substrates provides a barrier to electron flow while at the same time evenly distributing stress across the joint surface.Figure 8: An example of a multimetal closure assembly prepared for Shanghai VW to be used at the 2010 World Expo in Shanghai.Structural adhesive or Terocore can serve as a conductive barrier in the prevention of galvanic corrosion between dissimilar metals. This allows designers to utilize a reinforcement material that is different from the remainder of the section components. An aluminum extrusion or magnesium casting can thereby be bonded into a steel structure. The testing, whose results are shown in Figure 9, used the same box beams that have been discussed previously but rather than using an all steel construction these utilize different reinforcement materials. A designer can fine tune the system by means of material selection, balancing performance and mass. The beams illustrated here utilize a steel shell, but the same concept could be employed with an aluminum assembly, steel inserts could be added to reinforce local areas of concern by utilizing a Terocore composite solution.Figure 9: Weld flange separation and energy absorption at 130 mm de flection for box beam joined by spot welding only and joined by bonding using an impact resistant adhesive (no spot welding applied)The modern challenges placed upon vehicle design of improving vehiclecrash performance while at the same time improving fuel ef ficiency are often in con flict. In order to achieve both of these targets automotive designers much look to new processes, techniques and materials. Henkel Terokal structural adhesive and Terocore structural foams are two very useful tools have available. Both technologies enable the vehicle structure to work more ef ficiently. Terokal structural adhesive improves the ef ficiency of the structural joints, by distributing stress across the entire surface area. Terocore on the other hand improves the ef ficiency of the section, distributing load from component to component and preventing local buckling. Furthermore, Terokal structural adhesive and Terocore structural foam enable the use of multimetal assemblies. These bonding agents provide a continuous insulating layer which prevents galvanic corrosion and reduces or eliminates the need for mechanical fasteners. Without these concerns designers are free to select their material of choice where appropriate based upon speci fic vehicle requirements.[1] Wallentowitz H, Wohlecker R, Johannaber M, et al.

Development of a technique to strengthen body frame with structural foam [C]// SAE 2001 World Congress, No. 2001-01-0313,As consumers and governments around the globe press for improved crash safety they are met with con flicting demands: improve crash safety while also improving fuel ef ficiency. Common techniques of improving crashworthiness include increasing the gauge of the existing steel structural components, or adding additional reinforcements in critical areas where the vehicle structure buckles during impact. In each of these scenarios however signi ficant mass is added to the vehicle, a consequence that is somewhat counterproductive. While the structure is getting stronger it also is getting heavierwhich also means that at speed the vehicle has more kinetic energy. In order to meet the same level of crashperformance the now heavier vehicle must absorb more energy before it settles to rest.。

【进展】二聚酸型聚酰胺热熔胶的应用与改性研究进
【关键字】进展二聚酸型聚酰胺热熔胶的应用与改性研究进展刊物: C&P塑料专题提供者: China National Chemical Information Center (CNCIC)0 前言热熔胶是指室温呈固态、加热熔融后呈液态，将其涂敷于被粘物后，经压合、冷却，即可在短时间内完成粘接的胶粘剂。
由于热熔胶具有不含化学溶剂、无污染、使用方便和易于存储等优点，因而近年来其发展迅速、应用领域也不断扩大，其中聚酰胺(PA)是粘接性能最好的一种热熔胶。
PA热熔胶有两类：一类为高分子PA热熔胶(俗称尼龙型热熔胶)，主要用于服装、纺丝等行业；另一类为低分子PA热熔胶(常称二聚酸型PA热熔胶)，由二聚酸与二元胺或多元胺缩合而成，具有熔融范围窄、软化点高、无毒、耐油和耐化学性好、耐低温以及对极性材料粘接强度好等特点。
该产品具有很高的附加值，近年来市场需求量越来越大，可广泛用于制鞋、服装、电子电器、汽车、热缩材料及机械等行业[1]。
二聚酸型PA热熔胶的性能与其主要原料二聚酸的纯度、二元胺的种类等直接相关。
最普通的二聚酸型PA是以二聚酸和乙二胺为原料合成的，其软化点为105℃~110℃、相对分子质量较低且低温发脆，只能用于涂料、油漆等产品中，不能用作热熔胶。
为了提高二聚酸型PA热熔胶的性能和拓宽其应用领域，国内外研究者采用各种物理和化学方法对其进行改性。
1 应用领域二聚酸型PA热熔胶，因具有良好的韧性而广泛用于制鞋、制罐(包括罐头包装的边缝密封)、包装和书籍装订等领域；因具有突出的耐低温性能而用于冷冻苹果、桔子以及其他果汁的新型结构容器的粘接；因具有耐干洗性、耐强力洗涤剂、漂白剂及洗衣房与家庭的高温洗涤条件，对织物粘接强度大、使用方便而广泛用于织物的超强粘接；因具有必要的粘接力及优良的保气性而用于热缩性电缆套。
下面重点介绍其在制鞋、电子电器、汽车和热缩套管等领域中应用[2-3]。

【干货】汽车用胶那些事儿
【干货】汽车用胶那些事儿我们通常将车辆用胶粘剂大致分为：焊装工艺用胶、涂装工艺用胶、内饰件用胶、装配件用胶、特殊工艺用胶等5大类别。
焊装工艺用胶这一类的密封胶粘剂在焊装工艺中替代电焊或减少焊点，主要起着增强结构、密封防锈、减振降噪的作用。
一般要求与油面钢板有良好的附着性。
由于各工位均无专门的加热固化设备，需要在车身油漆工艺条件下固化，所以一般要求既不能受到清洗液、磷化液影响，也不能影响电泳漆质量，其市面上主要产品有：折边胶通常用在车门、发动机罩盖、行李箱盖等卷边结构处。
其粘接强度高，已完全取代点焊结构。
这类胶普遍采用单组份环氧树脂胶，常规单车用量在200g左右。
点焊密封胶预先涂布在钢板焊接的搭接部位，点焊后填实缝隙，起到密封、防止锈蚀的作用。
对于那些装配后被遮蔽而难以涂布焊缝密封胶的部位，点焊密封胶更是不可缺少。
膨胀减振胶在车门内外板之间、车身外覆盖件与加强筋之间常常用到这类胶。
它一般由合成橡胶或树脂添加发泡剂而成，经过固化膨胀，能将覆盖件同加强筋结合为一体，起到了减振降噪的作用，常规单车用胶量在400g左右。
涂装工艺用胶涂装工艺用胶虽然品种不多，但却是汽车上用量最大的一类。
通常单车用量：卡车约2kg，轿车在5kg以上。
主要有焊缝密封胶和抗石击涂料，其成分都为PVC塑溶胶。
两者虽然在性能上各有侧重，但是在工艺上都要求能够沟通过高压涂胶设备实施机械化涂布或者喷涂。
内饰件用胶汽车内饰件材料种类繁多，性质不同，应用场合各异。
所以，用胶品种还是存在一定区别，很难一概而论。
小编就其中部分品种略加介绍：车身顶棚胶用于将软质顶棚材料粘贴到车身顶盖上，增添车内美观性。
目前国内这一用途的胶粘剂多以溶剂型氯丁胶为主，在工艺和性能上要求初粘力高，满足车身内饰生产线快节奏的需要，并且避免引起内饰材料变色、脱落现象的产生。
丁基密封胶带它由丁基橡胶添加增粘树脂经挤压成带型，其特点有：贴合便捷，与钢板和防水膜均有较好的粘接性，能长期保持弹性和密封性。
