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. ***
