In the recent years, natural resins have received much more attention than ever before in the research community. The natural resins offer a number of advantages over commercial resins [1]. In the present communication a study on the synthesis and mechanical properties of Acacia resins reinforced with E-Glass fiber based polymer composites has been reported. Mechanical properties of intimately mixed Acacia resins reinforced polymer composites such as tensile, shear, adhesive and wear properties were investigated. Initially Acacia resin prepared was subjected to evaluation of its optimum mechanical properties. Then the natural fiber reinforced composite was cured under Ultra Violet radiation. Present work reveals that mechanical properties such as tensile strength, water resistance and wear resistance etc, of those natural resins increases to considerable extent when cured under Ultra Violet Radiation. It is also compared with synthetic resins. © 2006-2016 Asian Research Publishing Network (ARPN). All rights reserved.
