Pengaruh Sintering Serbuk Batuan Basalt sebagai Bahan Penguat pada Komposit Polyester terhadap Sifat Fisik dan Mekanik

Basalt rock has great potential in Lampung Province but is only used as a building construction material. superior characteristics such abrasion/wear resistance, compressive strength and chemical reaction resistance making it suitable filler or reinforcement for composites. This study aims to determine the effect of basalt powder sintering reinforcing on mechanical physical properties polymer matrix The parameters included variations temperature: 8500C, 9500C, 1.0500C, particle size: 100 < X 150 mesh, Y 200 mesh Z 270 volume fraction comparison polyester resin. 70: 30%, 80: 20%, 90: 10%. experimental design uses L9 3^3 taguchi orthogonal array run 9 specimens. Taguchi analysis shows that affect are temperature. temperature contributed 61.77% wear, 87.58% strength, 95.32% composite density. results with best value obtained wear 0.235 x 10-7mm2 / kg, 118.873 MPa, density 2.272 gr/cm3.
