In order to explore the mechanical response of Kevlar/EP armor materials using 3D curved shallow-crossing linking weave under bending load,the geometric structure model of the materials and bending head was established by using Pro/Engineer drawing software.ANSYS finite element software was used to analyze the mechanical response of the material under the bending displacement load of 0.5mm.The results shown that when the length of Kevlar/EP armor materials using 3D curved shallow-crossing linking weave was small,shear failure was the main factor leading to the failure of the material under the action of bending load.At the shearing position,the stress distribution of warp and weft was as follows:the upper layer>the middle layer>the lower layer.The warp played the main bearing role,the weft second,and the resin played the auxiliary role.The main failure modes of the materials were resin fragmentation,fiber and resin serious debonding and so on.
