Influence of filler proportion on mechanical and physical properties of particulate composite.

A particle reinforced composite material consisting of unsaturated polyester (UP) resin and fine dispersion of alumina trihydrate (ATH) has good mechanical properties. It performs well as laboratory or culinary bench top, in bathrooms as vanity top or sanitary ware, in maritime and agricultural applications. The goal of this study is to find out how the filler percentage in the composite influences the mechanical properties of the material and if it is possible to increase the concentration to lower the price. Test slabs with different proportion of filler were fabricated with vacuum assisted extruder. Test specimens were cut from post cured sheets and hardness, flexural strength, flexural modulus, deflection, and density were measured. It is shown that with higher percentage of ATH the flexural strength decreases and hardness and flexural modulus increases together with density.
