摘要
采用模压法制备了PEEK/GF/CNTs复合材料,研究了复合材料的力学、电性能、导热、耐摩擦等性能。结果表明：当CNTs含量为8%时,PEEK/GF/CNTs复合材料的拉伸强度最大为80.63 MPa;其导热系数随着CNTs含量的增加而增加,当CNTs含量为10%时,导热系数最大,为0.354 8 W/（m·K）;体积电阻率随着CNTs含量的增加而逐渐减小;当CNTs含量为8%时,PEEK/GF/CNTs复合材料摩擦系数最佳值为0.113;CNTs能有效阻止PEEK基体从PEEK/GF/CNTs复合材料表面翘起、剥落;CNTs的加入降低了PEEK的结晶性能。
PEEK/GF/CNTs composites were prepared by molding method, and the mechanical, electrical properties, heat conduction and friction resistance of the composites were studied. The results show that： when the content of CNTs is 8%, the maximum tensile strength of PEEK/GF/CNTs composites is 80.63 MPa. The thermal conductivity increases with the increase of CNTs content. When the content of CNTs is 10%, the maximum thermal conductivity is 0.354 8 W/（m·K）. The volume resistivity decreases with the increase of CNTs content. When the content of CNTs is 8%, the optimum value of friction coefficient of PEEK/GF/CNTs composites is 0.113. CNTs can effectively prevent the PEEK matrix from warping and peeling off the surface of the PEEK/GF/CNTs composites. The addition of CNTs reduces the crystallization of the PEEK.
