【摘要】 研究了莫莱石短纤维增强 ZL1 0 7复合材料中纤维体积分数的变化对其在 30 0°C时的高温蠕变性能的影响。实验结果发现 ,随着纤维加入量从 0到 8% ,2 0 %的增加 ,复合材料的高温抗蠕变性能随之提高。在本实验中 ,增强相的间接强化作用比直接强化作用更大更多还原

【Abstract】 The influence of fibre volume fraction (0,8%,20%) on the creep behavior of mullite short fibre reinforced ZL107 matrix composites is investigated at 300°C. It is found that with the increasement of fibre volume fraction, the composite material exhibits improved creep resistance. In these cases, indirect strengthening play a more important role.更多还原
