Abstract: Combinational designs were performed by using orthogonal and angular-interlocked structures,and two kinds of 3D woven fabric with different structures were woven accordingly with glass fibers on the trial basis.The fabrics were then reinforced with resin and the tensile strength property of the resultant composites was tested.The results show that the Young's modulus and tensile strength of the combinational 3D woven fabric reinforced composite are close to that of the 3D orthogonal woven fabric reinforced composite.
