碳纤维增强尼龙复合材料的性能研究
|
摘要
研究了碳纤维(CF)用量及助剂对碳纤维/PA66复合材料性能的影响。结果表明:复合材料的拉伸强度随着CF用量增加而增大,当CF质量分数超过15%时,增幅缓慢。在同一载荷下,随CF用量的增加,复合材料的摩擦系数先降低后升高,碳纤维质量分数为20%时,复合材料体系的摩擦系数最小,较PA66树脂降低了1/3;相容剂、耐磨助剂的加入,可有效改善CF/PA66复合材料的摩擦磨损性能。
The effect of carbon fiber(CF)content on the mechanical properties of CF/PA66 composites were studied.The results showed that the tensile strength of the composites increased with the increasing amount of CF,but,when the mass fraction of more than 15%,there was a slow increase.Under the same load,the friction coefficient of the composite system decreased first and then increased with increasing amount of CF,When CF mass fraction of 20%,the friction coefficient of the composite system was minimum,Compared with PA66 resin reduced by 1/3.Compatibility agents and wear aids have greater effect for centralizer compound system of CF/PA66 composite.
