摘要：
The negative Poisson's ratio (NPR) nano-size & alpha;-Cristobalite particle/epoxy composites were prepared and tensile tested. The elastic modulus and strength of the composites were improved as the particle volume fraction increased from 0 to 0.02. Unlike the conventional particle reinforced composites, the fracture strain increased with the nano & alpha;-Cristobalite addition, an effect which was ascribed to the intrinsic NPR behavior of the filler.
