摘要
本文采用细观力学模型和有限元法研究短纤维增强ＳｉＣ／Ａｌ复合材料在高温下的粘弹性行为，着重讨论了纤维体分比和长径比对复合材料总体蠕变性能的影响。结果表明，随着纤维体分比和长径比的增加，纤维能显著抑制复合材料沿轴向蠕变行为。
In this paper, The viscoelastic tensile behaviour of SiC short fiber reinforced Aluminum composites under high temperature is studied by using a micromechanical model and finite element method. Especially, the effects of the fiber's volume fraction and aspect ratio on the overall creep behavior of the composites are discussed. Numerical analysis results show that increasing the fiber's volume fraction and aspect ratio causes very substantial increase of the creep resistance of the composites.
