由克莱斯勒、福特、通用汽车和美国能源部组成的汽车复合材料联盟（ACC）正在进行一项重点项目，以展示复合材料在大批量结构应用中的应用，例如能够承受碰撞载荷的车身底部。关键挑战之一是在大批量汽车制造环境中将复合材料部件连接到钢结构上，并满足复杂的碰撞要求。焊接粘接，粘接和点焊的组合，被选为主要的连接方法。将双层钢带粘合到复合材料上的新概念使点焊能够连接到钢结构上，确保与OEM装配工艺的兼容性。接头的结构性能，包括耐久性，通过在各种温度下的准静态载荷下的分析和物理测试进行评估。本文讨论了实验的结果，旨在产生关键的建模参数的有限元分析的关节。
The Automotive Composites Consortium (ACC), a collaboration of Chrysler, Ford, General Motors, and the US Department of Energy is conducting a focal project to demonstrate the use of composite materials in high volume structural applications such as an underbody capable of carrying crash loads. One of the critical challenges is to attach the composite part to the steel structure in a high-volume automotive manufacturing environment and meet the complex requirements for crash. Weld-bonding, a combination of adhesive bonding and spot welding, was selected as the primary joining method. A novel concept of bonding doubler steel strips to composite enabled the spot welding to the steel structure, ensuring the compability with the OEM assembly processes. The structural performance of the joint, including durability, was assessed via analytical and physical testing under quasi-static loading at various temperatures. This paper discusses the results of the experiments designed to generate key modeling parameters for Finite Element Analysis of the joint.
