Effect Of Chestnut And Glass Powder On Some Physical And Mechanical Properties Of Polyester Composites

Natural resources decrease due to the increase of world population and consumption Th erefore, it is to use ofour natural resources more t man mer. Clag powders, the most widely used at over •90* of all reinforcements with thermoplastic or thermoset rmtrices, are available in rrany forrns to produce various commercial and industrial products All types ofglass powders have high therrmal resistance, Icø*' coefficient of thermal expansion high density and insulating properties Chestnut tree abundantly exists in the East Black Sea subsection, the Marmara region, and the Antalya coastal area via the West Anatolia subsection in Túrkey_ The nuts are used by confectioners, eater, roasted and ground to make four. In this study polymer matrix composites were manufactured using chestnut waste and glass powder as filler and polyester as polymer matrix with casting method. Polyester: filler ratio was kept in constant and chestnut: glass powder ratios were changed Some mechanical properties ofcomposite materials were investigated and final product to determine ther fiexural strength. elastic rr.odulus, hardness as well as some physical features such as density and water absorption The experimental results showed that increasing ratio of chestnut had led to decreasing of strength. Elastic modulus and hardness values were similar for all type of composites. Class powder added to chestnut in a ratio of 6% caused ta decreasing of strength in 18% Ceramic phase yielded an increase of approximately in the elastic modulus of the cornpc•sites. Generally im pact st'engt_h values were decreased with the increasing of ±escnut and glass powder filler ratio in all sam ples In addition impact strength of the composites Filled with glass powder has lower values •n comparision to composites Filled with only chestnut waste
