Abstract
The production of the basalt-based composite material was carried out using compression moulding. The selected materials basalt rock, bronze chips, cast-iron chips, glass fibre and phenolic resin were crushed into powder and sieved with a sieve size of 150microns. An optimization model based on the rule of mixture was developed to obtain the volume fractions of the constituent materials and a factorial Design of three levels and three factors was applied to obtained different sets of manufacturing parameters for the production of the samples using MINITAB 18 software. Twenty-seven samples with dimension of 20mm diameter and 8mm height were produced based on the formulation obtained from the optimization model and factorial design, this samples were subjected to tests. The test result shown that the basalt-based wear rate ranges from 9.0X10-5 to 1.52x10-4g/m and by volume is from 4.04x10-12 to 7.97x10-12m3/Nm. The density of the composites ranges from 2382.76 to 2781.33kg/m3. The Thermogravimetric Analysis (TGA) result shown that the basalt-based composites is thermally stable up to a temperature of 5300C before thermal degradation started setting in and Differential Thermal Analysis (DTA) result shown that the highest mass degradation occurred at a temperature of 6000C. Hence the basalt rock is a good material that can withstand high temperature.
