【Abstract】 Based on the two layers Kevlar/Epoxy fibre reinforced composite lamination, the influence of spread angle of sublayer on anti-penetration properties and variable energy absorbed by composite lamination under different velocity impact was analyzed by using nonlinear classical lamination theory. The anti-penetration properties of fibre reinforced composite lamination and the conclusion that the fibre reinforced composite lamination suits for anti-penetration of lower velocity were obtained.更多还原
