Abstract

In this study, epoxy composites with different reinforcement ratios of basalt and carbon fabric were produced. Al2O3 and SiC powders were added to the resin at different ratios. Reinforcements were not used in hybrid form. Each composite contains basalt or carbon fabric as fabric. Fabric reinforcement was determined as 30%, 40% and 50% by weight and powder addition was determined as 0%, 2% and 4% for Al2O3 and 0%, 5% and 10% for SiC. Izod pendulum impact strength test, tensile strength test and three-point bending test, which have different importance in different areas of use for composite materials and are the most researched mechanical properties, were selected. Taguchi experimental design (Mixed 3-6 Level) optimization technique was selected for the optimization of mechanical properties. The optimum Izod Pendulum Impact strength was obtained from the composite with 50% basalt reinforcement and 4% Al2O3 and 5% SiC. In the matrix, the optimum tensile strength was obtained from the composite with 50% basalt reinforcement and no Al2O3 and SiC in the matrix and the optimum Three Point Bending value was obtained from the composite with 30% carbon reinforcement and 2% Al2O3 and 5% SiC in the matrix. Comparison tests were carried out for this result and these results support the Taguchi analysis.
