Studying the effect of Polyamide 6 Nanofibers on Physical and Chemical Properties of Unsaturated Polyester Reinforced by Glass fibers Composites

Abstract

Abstract In this study, the hybrid reinforcement materials of (glass fibers and polyamide 6 nanofibers) with 15% weight fraction added to unsaturated polyester (UPS). The physical properties (density, bending strength, impact strength) and chemical resistance of UPS reinforced with of hybrid reinforcement (GF+PA6 nanofibers)with differen ratios: (0.99:0.01, 0.98:0.02, 0.97:0.03, &0.96:0.04) wt.% by 15% weight fraction were studied. Results proved that, the impact strength increased from 0.5 to 1.5 K.J/m2, while the bending strength increases from (2 to 14.5) MPa with adding of (0.96:0.04) wt.% of reinforcement materials by 15% weight fraction.The weight loss of (UPS/GF) decreased from (1 to 0.1) with (0.04) wt. % of PA6 Nanofibers for 30 days and it stable at this value for 40 days, this is refers to increases of chemical resistance of samples in H2SO4 acid. The density of (UPS/GF) decreased from (1.29 g/cm3) to (1.01) g/cm3 for density of (UPS/19.96GF+0.04 PA6 Nanofibers).
