Rice Husk Fibre (RHF) reinforced composite is prepare by blending unsaturated
polyester resin (UPR) from waste polyethylene terephthalate (PET) with RHF. The RHF
will be treated with sodium hydroxide follow by silane prior to inclusion into the UPR.
The untreated RHF 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. Therefore, the RHF composites with addition
of Dricon are significant as fire retardant composites.
