Abstract: In this paper, based on the structural advantages of 2-2 layer by layer orthogonal angle interlock fabric with lining warp structure, the corresponding composite materials were prepared, the tensile and shear properties were tested, and the mechanical properties of 2.5D woven composite materials in warp and weft direction were analyzed. It was found that the maximum tensile strength of the specimen in the longitudinal direction is larger than that in the longitudinal direction, and the longitudinal and latitudinal tensile fractures are more regular in the tensile test of the warp reinforced 2/2-angle interlock fabric reinforced composite; in the interlaminar shear strength test of the short beam of the warp reinforced 2/2-angle interlock fabric composite, when the longitudinal direction reaches the maximum failure load, the damage degree of the specimen is larger than that in the longitudinal direction, and some fibers are from the layer. The maximum interlaminar shear strength in the latitudinal direction is greater than that in the meridional direction.
