Influence of the Structure and Superelastic Properties of Titanium Nickelide on the Volume Fraction of the Reinforcing Filler in a Polyethylene–TiNi Composite Material

Abstract—Chemical composition and structure are shown to influence the characteristics of superelastic behavior of a NiTi alloy wire used as reinforcing filler in a composite material with a polyethylene matrix. A method is proposed to estimate the performance of titanium nickelide wire reinforcing elements during their bending deformation. A technique is proposed to calculate the optimum volume fraction of the filler, which ensures high superelastic properties of the composite material.
