Abstract :
UPR/LNR/glass fibre composite had been prepared by using unsaturated polyester resin (UPR) based from recycled PET product. PET waste was recycled by glycolisis process and the glycolised product was then reacted with maleic anhydride to produce unsaturated polyester resin. The preparation of UPR/LNR blends were conducted by varying the amount of LNR addition to the resin ranging from 0-7.5% (wt). The composition of UPR/LNR blend with good mechanical properties had been selected as a matrix of the glass fiber reinforced composite. Glass fibre was also treated by (3-Aminopropil)triethoxysilane as a coupling agent. From the result, the addition of 2.5% LNR in UPR had showed the optimum mechanical and morphological properties where the elastomer particels were well dispersed in the matrix with smaller size. The silane treatment on the glass fiber increased the tensile and impact strength values of the UPR/LNR/GF composite compared to untreated fiber reinforcement.
