Preparation and study the tribology properties for (epoxy resins/wood minutes (Reed) composite

The aim of this research is to study the influence of adding the residues of natural materials that are represented by using wood minutes (reed) on the epoxy, and to study the Tribology properties of composite. (Epoxy resins/Wood minutes(reed) Composite has been prepared by casting method with weight fraction (0, 20, 30, 40, 50) % and treated (reed) by sodium chloride solution (0.5), in addition the effect of the change in particle size of the wood (reed) has been studied, where its range (60, 150,212) µm. Tribology properties which include hardness, impact resistance, wear rate have been tested. The results show that the hardness rate of epoxy reduces which equal to 28, but after adding the reinforcement material of reed by weight fraction 20% to the epoxy it is observed that a clear improvement in the hardness values where its reaches to 34, it is also noticed the effect of the small particle size of the wood on the hardness rate is higher at 212µm, where hardness rate reaches to 61. The results of impact test illustrate that the impact resistance is increased with the increase of additive material (reed) for all particle sizes (60,150,212) µm and also for all weight fraction. the results of wear rate test show that the rate of wear for epoxy resin gives high values but when epoxy is reinforced by wood minutes (reed), this leads to obvious reducing in the wear rate.
