Experimental Study For The Tense And Pull-out Of Knotted Shape Memory Alloy Fiber-Reinforced Composite Materials

Shape memory alloy (SMA) materials possess unique properties of shape memory effect (SME) and superelasticity, which differentiate from the traditional functional materials govern their functions of sense to external conditions and actuation in whole system. So SMA materials have been paid great attentions by the researchers of scientific and technological fields, and they have been applied in many fields, such as navigation, aerospace, mechanism, electronics, communications industry and so on. In a word, SMA materials have a promising development future.Smart (or intelligent) composites gained by embedding SMA fibres into metal or polymer matrix have self-accommodation of strength and stiffness to external circumference. And the fracture in advanced composite structures can be actively controlled and repaired by use of shape memory effect and superelasticity of SMA. Recently years, the researches about SMA fibre-reinforced composites have been a focus and importance one of many researches of composites.The tensional and pull-out test of knotted shape memory alloy fiber-reinforced composite materials are put up in the article. The author experimentalize on the problem of the stress of pull-out, the effect on tense capability of composite materials by knotted fiber, experiment of the axial moduli of shape memory alloy fiber-reinfoced composite material and so on.
