• Abstract

In this study the mechanical properties of polymer composites reinforced with natural particulates are investigated. The epoxy resin used as a matrix material is Ep-10 and the reinforcement material was natural sand with particle size (25)μm and having weight fraction of 10%, 15% ,20% and 25% respectively .Specimens of the matrix material and the four types of composite materials were subjected to hardness tests. Experimental tests results indicate that hardness of the composite materials is significantly higher than those of the matrix material. The enhancements in these properties are found to be directly proportional to the weight fraction of reinforcement materials .the samples then immersion in water and chemical solution (HCl, NaOH) with concentration(1N) for 0,1,4,8,12,16 and 20 days. The effect of the chemical solutions has been studied on some physical properties (weight gain, hardness and diffusion coefficient) of epoxy before and after reinforced, and the results revealed obvious change in its physical properties.
