Abstract
1. from the metallic reinforcement aluminum gave the highest friction coefficient due to the formation of aluminum oxide which has high hardness.
2. Copper gave lower values of friction coefficient than the aluminum because of the formation of copper oxide which acted as a solid lubricant.
3. Iron produced high wear rate due to the friction between the same metal.
4. Long wires shared in carrying the load and dissipated or transmitted the heat generated from friction by conduction and so produced higher friction coefficient and lower wear values.
5. Metallic screens reinforced the specimens and produced higher friction coefficient.
6. Addition of glass fiber enhanced the friction and decreased wear.
7. Addition of barium sulfate enhanced the frictional behavior of the specimens and the wear resistance.
8. Addition of Cao increased the friction coefficient of the specimen.
9. Addition of barium sulfate decreased the friction and increased the wear.
10. from the agriculture fibers, straw increased the friction because the straw has a large amount of cellulose which is a very strong fibers but straw also increased wear.
11. Coconut fibers produced high friction coefficient comparing with banana and sugarcane in the rubber reinforced group.
12. Phenol increases the friction with the steel counter face which leads to decrease the specimens bonding while barium sulfate increases bonding.
