复合材料混杂效应h如rid effeet of Compositematerials混杂纤维复合材料的某一性能值偏离混合律计算值的现象。向增加偏离称为正效应，向减少偏离称为负效应。混杂效应可表现在许多方面，如强度、模量、疲劳、断裂功和断裂应变等方面。日本林毅(T.Hayashi)等在20世纪70年代初发现了断裂应变存在着正的混杂效应。他们用碳纤维与玻璃纤维混杂，用碳纤维与芳纶混杂，制成层内、层间混杂单向复合材料(见混杂复合材料)，其应力一应变曲线有如图示的现象。F刁|||||||!·对\--!.…片A!欲世/ / / /11·卜E应变 碳纤维/玻璃纤维混杂复 合材料的应力一应变曲线图中对应于直线部分的A‘点的应变为低伸长率纤维复合材料的破坏应变，而对应于直线的A点的应变为混杂纤维复合材料的破坏应变，后者大于前者。图中曲线OA段仍满足下式 瓜、二EcVc十凡凡十万而Vm式中EHY、Ec、凡、五m分别为混杂纤维复合材料、碳纤维、玻璃纤维、树脂基体的拉伸模量，Vc、凡、Vm分别为碳纤维、玻璃纤维、树脂基体的体积分数。从图可见，，棍杂纤维复合材料的断裂应变比低伸长纤维复合材料的断裂应变增加了40%，为正混杂效应。 J.吉兴(J ixing)研究了层间混杂复合材料的混杂效应和断裂模式，提出混杂效应系数Rt的概念，其表达式如下: 一〔H)~〔I)Rt二~于异匕 曰式中以H)、以I)分别为混杂纤维复合材料、低伸长率纤维复合材料的断裂应变。在分散度概念基础上，完善了分散度系数沪的表达式，并根据Rt的涵义及其与分散度系数、低伸长率纤维相对体积Vcf含量、混杂结构参数K之间的关系，建立了混杂效应系数估算式 Rt一矛·p·(l一K，)用上式估算的Rt与实测的值比较一致。用估算的Rt对混杂纤维复合材料的拉伸强度、模量的理论计算式进行修正，其计算值与实测值很好的符合一致。 混杂效应的产生是混杂纤维各组分相在力场中不同的行为以及相互制约的结果引起的。但对其机理尚无统一的理论解释。比较有代表性的有裂纹扩展理论、纤维束理论、断裂延伸率理论、固化残余应变理论、应变分布统计理论等。至于混杂纤维复合材料功能性能的混杂赫宙马甘娜佃尚/l》娜资
