Abstract Due to the special interlayer interlocking structure and relatively mature weaving and preparation technology, 2.5D woven composites have been widely concerned and applied in many fields. In this work, a carbon fiber 2.5D woven composite and a hybrid 2.5D woven composite of carbon fiber and glass fiber were prepared. The compression, bending and shear properties of two composites in warp and weft directions were studied, and the relationship between structure and properties was analyzed. The results show that the warp compressive strength of 2.5D fabric is higher than that of weft, and it is also better than that of 2.5D hybrid fabric composites; the weft compressive strength of 2.5D fabric and 2.5D hybrid fabric composites is very close; the warp bending strength of 2.5D fabric and 2.5D hybrid fabric composites is similar, and the weft bending strength of 2.5D fabric is significantly higher than that of 2.5D hybrid fabric composites; 2.5D fabric weft maximum interlaminar shear strength is greater than the warp interlaminar shear strength; there is little difference between 2.5D fabric and 2.5D hybrid fabric composites in the warp shear strength, while the weft shear strength of 2.5D hybrid fabric composites is much lower than that of 2.5D fabric composites.
