According to B4C matrix composite's structural characteristic, the physics model about its structure is set up. With the knowledge of stress wave, the propagation process of elastic wave in B4C matrix composite is analyzed primarily; and the result of stress is calculated. The investigation shows that its structural characteristic leads elastic wave propagation to diffuse, and lots of B4C/Al interfaces weaken the intensity of stress wave, and keep the B4C framework entire. Thus preventing B4C ceramic from big area cracks and improving ballistic performance of B4C matrix composites.
