Mechanical and Fracture Behaviors of Elastomer-Rich Thermoplastic Polyolefin/SiCp Nanocomposites

Elastomer-rich thermoplastic polyolefin (ETPO) resin containing 70 wt% maleated styrene-ethylene-butadiene-styrene (SEBS-g-MA) and 30 wt% polypropylene and its nanocomposites filled with 1–5 wt% SiC nanoparticles (SiCp) were fabricated using extrusion and injection molding techniques. The mechanical...

Summary:Elastomer-rich thermoplastic polyolefin (ETPO) resin containing 70 wt% maleated styrene-ethylene-butadiene-styrene (SEBS-g-MA) and 30 wt% polypropylene and its nanocomposites filled with 1–5 wt% SiC nanoparticles (SiCp) were fabricated using extrusion and injection molding techniques. The mechanical and thermal behaviors of ETPO and its nanocomposites were investigated. Tensile measurements showed that the SiCp additions lead to reductions in both tensile stiffness and strength of ETPO. However, Izod impact and EWF measurements indicated that the impact strength and fracture toughness of ETPO improve substantially with increasing SiCp content. This demonstrated that SiC nanoparticles toughen the ETPO blend effectively. Furthermore, SiCp additions were found to improve the thermal resistance of ETPO blend considerably.
