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 ?-Cristobalite addition, an effect which was ascribed to the intrinsic NPR behavior of the filler. © 2023 Elsevier B.V.eninfo:eu-repo/semantics/closedAccessDeformation and fractureNanocompositesNanoparticlesPolymersDuctile fractureFilled polymersArticle2-s2.0-8516213426110.1016/j.matlet.2023.134759
