Abstract :In this study, some of the mechanical properties of basalt fabric and carbon fabric reinforced particle additive composite materials were investigated. The effect of fabric additive ratios on tensile strength, Izod pendulum impact resistance, and three point bending properties has been tried to be revealed. In order to determine the composite material that gives the optimum mechanical properties, Taguchi Grey Relational Analysis (Taguchi based GRA) method was chosen as multi-objective optimization method and used L18 (Mixed 3-6 Level) experimental design. Input variables-factors were determined as fabric (6 levels), Al2O3 additive (3 levels) and SiC additive (3 levels) according to the design. Tensile strength, impact resistance, and three point bending were selected as response variables. These three tests were optimized. The optimum composite combination was determined and found 30% carbon fabric, 4% Al2O3 and 0% SiC. The improvement by using confirmation test was seen as 0,07 when the 3rd experiment plan was selected as the initial process parameter.
