Kenaf fibre (KF) reinforced composite is prepare by blending unsaturated polyester
resin (UPR) from waste polyethylene terephthalate (PET) with kenaf fibre. The KF will
be treated with sodium hydroxide follow by silane prior to inclusion into the UPR. The
untreated KF reinforced composite is use as a control. Dricon as a phosphate type of
flame retardant with different amount will be added to reduce the flammability of the
composite. The burning properties, limiting oxygen index (LOI), tensile strength and
modulus of both composites will increase with the addition of Dricon. In addition,
thermogravimetry (TGA) analysis indicates the degradation temperature will increase
with the addition of Dricon into UPR. Morphological observations also indicate better
distribution of Dricon for treated fibre composite result in enhancement of the tensile
properties of the treated fibre composite. In conclusion, the KF composites with
addition of Dricon are significant as fire retardant composites.
