Studying of Mechanical and Physical Properties of Polyester Composite Reinforced by Cows and Buffalo Horns

Abstract

Cows And Buffalo Horns waste particulate have been used as non-chemical reinforcement particulate to improve several features of polyester polymer, the particles of the cow and buffalo horns waste particles were used in three particle size 15, 200, 𝑎𝑛𝑑 300𝜇𝑚, at rates of 0, 2.4, and 6%, where the reinforcement process by the horns waste particles, where the hardness values have been increase from (60 to be 80), Young Modulus from 0.137 𝑀𝑃𝑎 to be 8.951 𝑀𝑃𝑎, while the density values have been deceases from (3.78 to 2.08) g/cm3 as a result of light weight of horn waste particles and the creation of voids and pores the reinforcing particles during the preparation process and the light weight (low density) of the reinforcement horn particles, in addition to that the thermal conductivity increases from (0.818 to be 1.489) W∕𝑚.℃.
