摘要: 本文首次对聚合物基纤维增强复合材料的蠕变混合律进行了研究。推导出具有正交双向铺设纤维复合材料的微观力学模型,用此模型对聚合物基纤维增强复合材料的蠕变性能进行了预测,并对其线性蠕变混合律进行了实验验证。实验结果表明,这个理论对复合材料线性蠕变的预测是很精确的。Abstract: In this paper,the creep mixture rule of polymer matrix fiber-reinforced composites is studied.A micromechanical model of composite with fibers in two vertical directions is obtained.With this model,the creep property of composites with polymer matrix is calculated and the creep mixture rule tested in the linear creep range, The egperimental results. show that this theory is very precise for calculating the linear creep of composite materials.
