Study of some Properties of Polyester Resin Reinforced by Natural Wool


In this study polymer matrix composite was prepared by hand lay –up molding method. Unsaturated polyester resin was used as a matrix to the composite material and natural wool fibers were used as reinforced filler with different percentage as (3%, 4% and 5%).In this study some properties were studied at room temperature (Impact resistance, Modulus of elasticity).Also Dielectric constant was measured. The results showed that the value of the Impact resistance of the composite increases with the increase of the fiber percentage, while the Modulus of elasticity decreases. Dielectric constant increases with increasing the wool fiber percentage.
