根据反对称四点弯曲原理，自制了一套用于测试编织复合材料剪切模量的夹具，并通过实验得到了三维四向碳／环氧编织复合材料剪切模量．将实验结果与理论计算进行了对比，两者吻合较好．
According to the four-point bending principle of anti-symmetry, a set of jig for testing the shear modulus of the braided composites was fabricated and the shear modulus of the three-dimensional four-direction carbon / epoxy braided composites was obtained through experiments. The experimental results and theoretical calculations are compared, the two agree well.
