Investigation on Mechanical Properties of Epoxy/Polyester Based Composites
Polymer glass fiber reinforced composites plays a vital role in day to day life. The aim of this research Article is
processing of Epoxy and polyester based composites reinforced with Glass Fiber and filled with the natural fillerArabic
Gum Tree Coal Powder (A.C.P) which is prepared by carbonization of Arabic Gum Tree Stem. Manual hand layup process
is adopted for preparation of composite with 2.5wt%, 5wt% and 7.5wt% of A.C.P. with Glass fiber of 40 wt% reinforced in
Epoxy/Polyester resins by varying their compositions with respect to the composition of the filler material. After the
preparation of composites with the compositions, specimen were prepared as per ASTM Standards for Mechanical
characterizations. Tensile Strength, Flexural Strength, ILSS, Impact Strength and Hardness were determined.
