Influence of thermal conditions on the tensile properties of basalt fiber reinforced polypropylene–clay nanocomposites
Highlights We studied tensile properties of basalt fiber/nanoclay-polypropylene (BF–PPCN). Addition of nanoclay improves the yield strength and Young’s modulus of BF–PPCN. The tensile properties of BF–PPCN are high at low temperature (−196°C).
Abstract In this paper, a comparative study on the tensile properties of clay reinforced polypropylene (PP) nanocomposites (PPCN) and chopped basalt fiber reinforced PP–clay nanocomposites (PPCN-B) is presented. PP matrix are filled with 1, 3 and 5wt.% of nanoclays. The ultimate tensile strength, yield strength, Young’s modulus and toughness are measured at various temperature conditions. The thermal conditions are included the room temperature (RT), low temperature (LT) and high temperature (HT). The basal spacing of clay in the composites is measured by X-ray diffraction (XRD). Nanoscale morphology of the samples is observed by transmission electron microscopy (TEM). Addition of nanoclay improves the yield strength and Young’s modulus of PPCN and PPCN-B; however, it reduces the ultimate tensile strength. Furthermore, the addition of chopped basalt fibers to PPCN improves the Young’s modulus of the composites. The Young’s modulus and the yield strength of both PPCN and PPCN-B are significantly high at LT (−196°C), descend at RT (25°C) and then low at HT (120°C).
