Composite Materials for Automotive Body: Balancing Weight Reduction and Safety

With the growing number of automobiles, the demands from both government and consumers for fuel economy and automotive safety are also on the rise. To meet these requirements, the article outlines some key properties required for automotive body materials. It delves into the characteristics of fiber-reinforced composites and sandwich structures. For example, it provides data on the impact strength and Young's modulus of Carbon Fiber Reinforced Polymer (CFRP), which is highly useful in selecting materials for the vehicle body. Finally, the article highlights several applications of composite materials in automotive body components, including support structures, bumpers, hoods, and chassis. This article primarily summarizes past research and provides direction for future studies.
