Abstract
In this study sewage sludge ash (SSA) particles were used as filler in the polyester resin to fabricate particulate composites with various filler contents of 0, 1, 2, 3, 4, 5, 6 and 7 wt%. The tensile, flexural, impact, hardness, chemical composition and scanning electron microscope tests wear done on the samples in accordance with ASTM standards. The results were improved at the particle content of 5 wt% for the tensile and flexural strength and then showed reducing trend with extra particle addition. Tensile and flexural modulus values of the particulate polyester composites significantly enhanced compared with the unfilled polyester composite. Energy Dispersion Spectrometry (EDS) results showed that the SSA contains elements and oxides which may increase adhesion force with polymer. In spite of the particle content of SSA that used with polymer to produce various structures for different applications was low, this study approved that using of SSA can protect the environment due to increasing the amount of SSA can affect the environment badly in addition to produce cheaper polymer composite for industrial applications.
