结构胶和结构泡沫——改善碰撞性能的可行技术(英文)

Crash Performance Enabling Technologies,Structural Adheise and Structrural Foam

为了新能源车的整车轻量化并保证其安全性,Henkel公司完成了两项新技术——结构泡沫和结构胶。该文测量了该组材料的物理、化学特性,以便实际应用和提高整车性能。结果表明:一种结构泡沫具有质量轻、强度和刚度高的优点,应用该种泡沫可减轻车辆自重,节省成本,在碰撞情况下提高车辆骨架对能量的吸收;另一种结构胶可提供有效连接方式,优化连接处应力分布,提高结构整体的强度和刚度,防止不同金属材料之间的电腐蚀,从而也降低生产成本。许多汽车生产商已经将该两项技术用于整车生产线上。

A structural foam and a structural adhesive produced by Henkel Co.were introduced contributing to light weight construction and automotive safety for new energy automotive industry.Of these two new solutions,the chemical aspects,mechanical properties were measured for automotive application cases and the improvement contributions to vehicle performance.The results show that the structural foam has the excellent properties of being lightweight,providing both high strength and stiffness,therefore,offering many weight saving and cost reduction solutions,thus,increases the energy absorption capacity of the vehicle structure during collision situations;the structural adhesive provides an effective joint line,optimizing stress distribution,increasing structural strength and stiffness,preventing galvanic corrosion,and hence can also provide alternative cost reduction opportunities.These technologies were used by many OEMs（Original Equipment Manufacturer） on automotive production lines.
