An experimental study has been carried out to investigate tensile, bending, impact and hardness properties of chopped carbon fiber reinforced epoxy composites. Four different weight fractions (0%, 6%, 8%, 10%) were added as reinforcement to composites. The samples were manufactured by using a special designed mold. Tests were carried out according to the ASTM standards. Results of the tests have shown that hardness increases with the increasing amount of carbon fiber in composites. Tensile, bending and impact performances have increased up to 8% of carbon fiber in the composite and then started to decrease.

E-glass fiber reinforced epoxy composites were fabricated by hand lay up method and tested for investigating tribological behaviours. Wear behaviours of composites 0• , 90• ] oriented were investigated by pin on disc wear tester device for a constant distance (1000 m) and the design of experiments approach using the Taguchi method was employed. The tests were conducted sliding against a steel disc (60 HRC) under different sliding and loading conditions. Signal to noise ratio and analysis of variance (ANOVA) were used to investigate the influence of parameters on the wear rate and coefficient of friction.

Chopped carbon fiber-reinforced epoxy composites were fabricated and tested for tribological behaviour. Wear behaviour of composites was studied using pin-on-disc wear tester device. The design of experiment, using Taguchi method, was employed to analyse the results. Signal to noise ratio and analysis of variance (ANOVA) were used to determine the influence of parameters on the wear rate and coefficient of friction.
