Along with the development of the automobile industry, the materials and processing technology of parts have also developed. In particular, various materials have been developed and applied to automobile bumpers, which are directly related to crash safety. In particular, the application of composite materials is expanding for weight reduction. In this study, a new composite material made of a mixture of carbon fiber and aramid fiber was developed and the possibility of application to an automobile bumper was reviewed, and significant results were obtained.
