Energy absorption composite material

The invention relates to the field of fiber reinforced composite materials, and particularly relates to an energy absorption composite material. The energy absorption composite material is of a layered structure; the upper surface layer is aramid fiber cloth, the lower surface layer is aramid fiber cloth, the interlayer is glass fiber cloth, and the matrix is aromatic resin; the aramid fiber clothand the glass fiber cloth are both plain bidirectional fiber fabrics; and the volume ratio of the upper surface layer to the interlayer to the lower surface layer is 1:2:1. The energy absorption composite material disclosed by the invention is good in energy absorption effect and low in price and can improve the tensile elasticity modulus. 本发明涉及纤维增强复合材料领域，具体是一种吸能复合材料；吸能复合材料为层结构；上表层为芳纶纤维布；下表层为芳纶纤维布；夹层为为玻璃纤维布；基体为芳烃树脂；芳纶纤维布、玻璃纤维布均为平纹双向纤维织物；上表层、夹层、下表层的体积比为1：2:1；本吸能复合材料吸能效果好，价格便宜，且能提升拉伸弹性模量。
