Design and Analysis of Smart Composites

9414696 Taya该研究将探索在铝和环氧树脂基复合材料中使用TiNi形状记忆合金纤维和增强材料。 将形状记忆合金用于纤维增强可导致在复合材料的基质相中产生压缩残余应力。 与当TiNi未被处理以在复合材料中产生形状记忆效应时相同复合材料中的这些性质相比，这可导致复合材料的流动应力和韧性增加。 TiNi形状记忆合金化处理在基体中产生的压应力是提高复合材料拉伸性能和韧性的主要原因。 通过形状记忆增强材料诱导理想的应力状态来增强复合材料的机械性能的概念是创新的，该研究非常值得支持。 ***

9414696 Taya The research will explore the use of TiNi shape memory alloy fibers and reinforcements in aluminum and epoxy matrix composites. The use of a shape memory alloy for a fiber reinforcement can result in the production of compressive residual stresses in the matrix phase of the composite. This can result in increases in flow stress and toughness of the composite as compared to these properties in the same composites when the TiNi was not treated to produce a shape memory effect in the composite. The induced compressive stress in the matrix as a result of the shape memory alloy treatment of TiNi is responsible for the enhancement of the tensile properties and toughness of the composite. The concept of enhancing the mechanical properties of composites by inducing desirable stress states via shape memory reinforcements is innovative and the research is well worth support. ***
