摘    要: 对多向复合材料(包括单一及混杂纤维复合材料)在室温至150℃温度范围内的热膨胀性能进行研究,推导了热膨胀系数(CTE)的理论计算公式,对零膨胀的多向复合材料的铺层设计进行了探讨,并对部分零膨胀复合材料铺层结构进行了预测,其结果与实验值基本吻合。

关 键 词:混杂  复合材料  层板  热膨胀系数

Abstract:In this paper, thermal expansion properties of single and hybrid multi-directional composites from r.t. to 150℃ arc studied. The theoretical formulae for predicting coefficient of thermal expansion (CTE) value arc established. In the experiments, carbon/glass and carbon / Kcvlar arc accepted to be the hybrid form. The variation of CTE values of hybrid composites with structure parameters is analyzed. Besides, hybrid composites with zero CTE are studied and designed. And some typical ply forms of laminates with zero CTE are presented. The investigation shows that it is easier for hybrid multi-directional composites to meet the requirement of zero-expansion.
Keywords:composites  hybrid  coefficient of thermal expansion  laminate
