Abstract

Coconut fibre reinforced composite was prepared by blending unsaturated polyester resin (UPR) from waste PET with 0.3 v% of coconut fibre. The coconut fibres were pre-treated with sodium hydroxide followed by silane prior to inclusion into the UPR. The untreated coconut fibres reinforced composite were used as a control. Dricon as a phosphate type of flame retardant was then added to the composite to reduce the flammability of the composite. The amount of Dricon was varied from 0 to 10 wt% of the overall mass of resin. The burning properties and limiting oxygen index (LOI) of the treated and untreated composites increased with the addition of Dricon. The tensile strength and modulus of both composites were also increased with the addition of Dricon. The treated fibre composite with 5 wt% Dricon showed the highest burning time and LOI with the values of 101.5 s and 34 s, respectively. The optimum tensile strength and modulus for treated fibre composite was at 5 wt% Dricon whereas the untreated fibre composite was at 2.5 wt% loading of Dricon. Thermogravimetry (TGA) analysis indicated that the degradation temperature increased with the addition of Dricon up to 5 wt% into UPR/coconut fibre composites. Morphological observations indicated better distribution of Dricon for treated fibre composite resulted in enhancement of the tensile properties of the treated fibre composite.
