Composite materials are combination of at least two components and structure a novel material with properties unlike from individual components. Most composites are poised of a reinforcement material, generally fibers. The reinforcement materials typically have exceptionally high tensile and compressive strength. The present work is aimed to determine the optimum fiber angle of pipe when fabricated with composite material like glass fiber and epoxy resin. FE analysis tool Ansys is used to determined to the fiber angle based on their deformation strains and stresses, maintaining the fiber volume fraction of 50%.. This optimum fiber angle is found on the comparing the results of Mild Steel and Composite Tube.
