Abstract

The industry is increasingly required to develop vehicles with better performance and composites materials are often the first option due their high mechanic resistance combined with low density. In order to apply this material on CVT protection of BAJA style car, this work main purpose was to study the impact behavior of the carbon fiber and epoxy resin composites, varying the fiber orientation, and compare to the SAE 1010 steel. For that reason, it were performed Charpy impact tests on the steel and on the unidirectional (0° and 90°), 0°/90°, ±45° and mixed (0°/90°±45°) configurations composite material. The results showed that defects inserted during the manufacturing process provided a huge influence on their energy absorbed. It was seen that higher energy absorbed occurred due damage mechanisms release energy. As a conclusion, the ±45° showed the best performance
