Abstract

The matrix and filler used are polypropylene and stone wool. Stone wool is a natural material that is formed from one of earth’s most abundant material. It become a mass of fine, intertwined fibres with a typical diameter of 6 to 10 micrometers after an advance process. The main purpose of using stone wool is because of its very good properties such as an insulator, ease of control, lightweight, consistently high quality and sterile production under extreme temperature and etc. By using stone wool, a new improvement in material world will happen especially in PMC. The investigation of mechanical properties of stone wool composite compared with virgin material, Polypropylene (PP) carried out as a new research. The filler had been prepared by cleaned and dried before mix with PP in four weight ratio, which are 10wt%, 20wt%, 30wt%, and 40wt% by internal mixer. The compounded composite then compressed into sheet and cut into size as 45 samples for tensile test, hardness test, flexural test and SEM. The result showed that the filler had improved the tensile strength and yield strength up to 20wt% stone wool reinforced PP and decreased after that ratio. 20wt% also showed the lowest for tensile modulus. Addition of filler had improved the flexural modulus but not for flexural strength and flexural strain. The pure PP showed the best flexural strength and strain when compared with the stone wool reinforced PP. The hardness test results showed that the hardness improved with the increase of the filler weight ratio.
