摘要
制备了一种针刺结构碳纤维织物增强的环氧树脂基复合材料,所制备的复合材料面内拉伸强度为121 MPa,水平剪切强度为14 MPa,压缩强度为290 MPa,其中水平剪切强度离散度较大,表现了碳纤维针刺预制体Z向纤维引入量的不确定性。
Carbon Fiber Needling Preform Reinforced Epoxy Resin Composites were prepared. The composites exhibit mechanical properties with tensile strength in-plane of 121 MPa, horizontal shear strength of 14 MPa and compressive strength of 290 MPa. And the dispersion of horizontal shear strength is large, which shows the non-determinacy of Z-direction fibers.
