| Abstract: | With a view to develop polymer-matrix composites of high mechanical strength, composites containing 0.5% to 5.0% of each of calcium carbonate or white cement were prepared by uniformly mixing polystyrene and inorganic materials followed by casting in an aluminum mold. The values of fracture toughness, flexural strength and elastic modulus were found to increase with increasing amount of the inorganic component in the polymer. In addition, for a given percentage of inorganic components, the values of mechanical strength of white cement containing composites were found to be more than those of calcium carbonate containing composites. The optical microphotographs of the composites show that there is uniform distribution of filler in the polymers. |
