Abstract:
Based on three dimensional machine woven enhanced composite, single cell model was established by limited element software ABAQUS. Spread of the stress wave about bullet in three dimensional woven fabric reinforced composite was also analyzed. The bullet impact of experiment results and simulation calculation of results were compared and the eventually damage mode of three dimensional woven fabric reinforced composite and layer collection board was analyzed. The results showed that maximum stress of bullets in three-dimensional woven fabric reinforced composite stress increases with the speed of the input and reflected back and forth; after the warhead projected from three dimensional woven reinforced composite, the reinforced yarn of fracture in lower surface is rougher than it in upper surface; there was no obvious stratification phenomenon in three dimensional woven fabric reinforced composite, the graphics of finite element simulation are consistent with the actually observed damage voids.
Key words: three-dimensional woven, composite, ballistic impact, finite element, simulation
