Preparation and Characterization of Mechanical Properties of Glass Powder Reinforced Composites with Isopthalic Polyester Resin as Matrix

Polymers are important matrix materials for forming advanced composites. The effect of the weight fraction of reinforced particles on mechanical properties in polymeric reinforced composites were investigated. In our work, Isopthalic Polyester is used as matrix material and glass powder with 200 mesh size as filler material to prepare composite lamina. Isopthalic Polyester resin was filled with glass powder with a view to increasing strength of the composite. This project varies the percentage by weight of the glass powder in the composites from 10% to 40% which are then subjected to Flexural and Tensile tests. The results show that composite with 30 % by weight of the glass powder produces the highest Flexural strength, Young's modulus and Ultimate Tensile strength; the highest deflection was achieved when the percentage by weight of glass powder is 10 %. Increase in addition of glass particles weight % from 0 to 30 % improved the observed mechanical properties relatively but found decrease in same properties for 40 % composite lamina.
