The improved thermal and mechanical properties of polyurea nanocomposites with SiC

Abstract Polyurea as one kind of polymer is widely used in the field protective under blast and impact loading. matrix with nanofillers has superior mechanical properties than pure polyurea. In this work, order to develop polyurea thermal stability high properties, using Silicon carbide (SiC) nanofillers, nanocomposites different content SiC nanoparticles were prepared via in-situ polymerization method. The morphology structure SiC/polyurea characterized by SEM, XRD FTIR. From studies, had not altered basic Thermal also studied TGA tensile testing machine, respectively. results indicated that incorporation (1.5 wt%) into could obviously improve comparation enhancement performance relative reinforced temperature SiC. At higher SiC, tend decrease. It can be inferred from have potential for structures.
