Besides, the impact resistance and tensile strength of composites were tested by impact testing machine and universal testing machine. The results show that the textile mechanical properties of composites can improve through reasonable stacking sequence design, and among the laminate structures, the composite which arranging alternately with two different structures of fabrics can obtain high energy absorption and a better tensile strength in warp and weft .
