Carbon fibers are made into four different structures, laminated fabric, 2.5D woven fabric,orthogonal fabric and three-dimensional braid fabric, with progressive degree of connection between the layers. Then they are used as the reinforcing material to produce the textile composites. The impact properties are studied by low speed impact tests and the effects of that with their interlacing regularities are analyzed. According to the impact record curves and the sample failure characteristics, the impact resistances with four different structures are compared. The results show that the impact resistance of the four textile composites, from strong to weak, is orthogonal fabric, 2.5D woven fabric, laminated fabric, three-dimensional braid fabric.
