The proposed research aims to investigate the potential for substantial weight reduction of front end automotive structural components using high performance carbon fiber reinforced plastic (CFRP) composite materials fabricated by a rapid high pressure resin transfer moulding (HP-RTM) process. These materials are known for their high specific strength and stiffness characteristics, low densities (1.5 g/cm3) and high energy absorption capabilities under crash conditions, and have been identified as key materials for enabling substantial weight reductions in mass market vehicles. Although high performance CFRP composites have not been integrated into frontal crash structures of automobiles to date due to high cost and manufacturing time constraints, newly developed processing techniques such as HP-RTM can provide the required rapid production rates that will allow the realization of CFRPs into mass-market vehicles. The research will address fundamental material characterization and part fabrication processing challenges in order to develop an accurate impact simulation platform, which will be required to integrate high performance lightweight CFRP composites into energy absorbing structures of next-generation automobiles. The inherent processing defects will be assessed, and coupled to the highly complex deformational response of the CFRP composite in order to predict impact performance of CFRP parts. As a validation, fabricated CFRP parts with differing geometries representative of frontal vehicle structures will be tested under various loading conditions and the model predictions will be assessed against the experiments.

拟议的研究旨在研究使用高性能碳纤维增强塑料（CFRP）复合材料大量减少前端汽车结构组件的潜力，该材料是由快速的高压树脂转移成型（HP-RTM）工艺制造而成的。这些材料以其高的特异性和刚度特性，低密度（1.5 g/cm3）和高能量吸收能力在崩溃条件下而闻名，并已被确定为可实现大量市场车辆重量减轻重量的关键材料。尽管高性能CFRP复合材料由于高成本和制造时间限制而迄今尚未集成到汽车的正面崩溃结构中，但新开发的加工技术（例如HP-RTM）可以提供所需的快速生产速度，从而可以将CFRP实现到大众市场中。该研究将解决基本的材料表征和部分制造处理挑战，以开发准确的影响模拟平台，这将是将高性能轻质CFRP复合材料整合到下一代汽车的能源吸收结构中所必需的。将评估固有的处理缺陷，并与CFRP复合材料的高度复杂的变形响应耦合，以预测CFRP零件的影响性能。作为验证，将在各种负载条件下测试具有不同几何形状代表的代表不同几何形状的CFRP部分，并且将根据实验评估模型预测。
