| Abstract | ||
| In the present study the epoxy resin was used as a matrix. Glass fibers and steel fibers were used with equal content at different ratios (2.5,5,7.5and 10%) as a reinforcing fibers, molybdenum trioxide and calcium carbonate as filler, zirconium oxide as abrasive material and copper sulfides as a lubricant. The current work investigates the mechanical characteristics by increasing fibers ratio. The wear lost get more stable state with molybdenum tri –oxide adding more than Calcium carbonate .Wear test was carried out by using pin on disc device. Results showed that the friction coefficient, compression strength, impact resistance, young modulus and wear lost improved with the change of the filler and fibers ratio. The result showed that compression strength, impact resistant, wear lost, young modulus and hardness enhanced when molybdenum tri-oxide filler was used well than calcium carbonate using. | ||
