Crash Simulations of CFRP Structures for Automotive and Racing Applications

This paper presents a study on CFRP structures crash simulation. In particular, the focus is on the implementation of a modeling methodology for applications in automotive and racing fields. The study is conducted on an omega-shaped monolithic specimen. A preliminary static testing phase is performed to characterize the material mechanical properties in tension, compression, and shear; then, the laminate toughness is measured in order to quantify the delamination resistance. The experimental data are used to define plies and interface properties for the FE model representative of the specimen in the numerical simulation of crash testing. Quasi-static and dynamic compressive tests are eventually executed in order to validate the methodology.
