Abstract:

The SiC ceramic is the perfect ballistic material in the modern war because it has lower density, the weight is lighter and the cost is moderate. In this paper, the shearing academic modular of the epoxy resin matrix composite enforced promiscuously by SiC nano fiber and Twaron staple was built and proved by the way of mathematic deduced and testing validated. And the shearing characteristic was analyzed. The result shows that the total volume percentage of the enforced fiber is bigger, and the shearing modulus of the composite is higher. The modulus of the composite would be higher if that of the matrix is bigger. If the volume percentage of the fiber with lower shearing modulus is bigger, the modulus of the composite would be lower. The mainly factor which influenced the shearing characteristic of the composite is not the shearing properties of the enforced fiber, but that of the epoxy matrix. The effect to the shearing characteristic of the epoxy resin composite enforced by the mixture of SiC nano fiber and Twaron staple is plus certainly.
