Fracture Toughness of Polyamide 6/ Maleated Styrene-Ethylene-Butylene-Styrene/Silicon Carbide Nanocomposites

Abstract:

Article Preview

Polyamide 6 (PA6) based nanocomposites toughened with 20 wt% maleated styrene-ethylene-butylene-stryrene (mSEBS) reinforced with 1-7 wt% silicon carbide nanoparticles (SiCp) were fabricated via melt blending followed by injection molding. Tensile results showed that SiCp additions improve the Young’s modulus and tensile strength of PA6/mSEBS blends but decrease their tensile ductility and impact strength. EWF test revealed that the SiCp additions reduce both the specific essential work of fracture and specific non-essential plastic work of fracture. Thus SiCp additions are detrimental to the fracture toughness of PA6/mSEBS blend.
