摘　　要：通过物理方法对碳纤维进行了包覆处理,并研究了碳纤维含量对兵乓球桌碳纤维复合材料力学性能和耐磨性能的影响。结果表明,经过改性处理后的A1、A2、A3和A4的结晶温度都相较于PEEK有不同程度减小,但是熔融温度都高于PEEK,B组试样的结晶温度和结晶度都会随着碳纤维增大而小。A组试样中m-ZnO含量为5%时具有最大的拉伸强度和弯曲强度,B组试样中w-SCF含量为20%时具有最大的拉伸强度和弯曲强度。经过改性后的A1、A2、A3和A4的摩擦系数都相较于PEEK试样有不同程度减小,A3试样的摩擦系数最小;B组试样的摩擦系数会随着w-SCF含量的增加而呈现先减小而后增加的趋势,B3试样的摩擦系数最小,添加w-SCF的复合材料的摩擦系数都要低于未添加w-SCF的复合材料。经过改性处理的A组试样的磨损率都明显低于PEEK试样,B组复合材料的磨损率会随着w-SCF含量的增加而呈现先减小而后增大,B3试样具有最小的磨损率。Carbon fibers were coated by physical methods,and the effects of carbon fiber content on the mechanical properties and wear resistance of carbon fiber composites for table tennis table were studied.The results showed that the crystallization temperatures of modified A1,A2,A3 and A4 were lower than that of PEEK,but the melting temperatures were higher than that of PEEK.The crystallization temperatures and crystallinity of group B samples decreased with the increase of carbon fibers.The tensile strength and flexural strength of group A were the highest when the content of m-ZnO was 5%,while that of group B were the highest when the content of w-SCF was 20%.Compared with PEEK,the friction coefficients of A1,A2,A3 and A4 after modification decreased to the some extent.The friction coefficients of group B decreased first and then increased with the increase of w-SCF content.The friction coefficient of sample B3 was the smallest.The friction coefficients of composites with w-SCF were lower than those of composites without w-SCF.The wear rates of group A after modification were lower than that of PEEK,the wear rate of group B composite decreased and then increased with the increase of w-SCF content,and the wear rate of sample B3 was the lowest.
