Contemporary researches have emphasized on development of composite materials due to its mechanical properties and effective results. Composite materials are useful because of their characteristics such as light weight, cost friendly and high heat resistant. Composite materials are in the designing and manufacturing of sports cars, wind energy systems, and aerodynamics systems, where main problems are like; weight, strength along with resistance to oxidization. Latest researches have focused on new type of composite materials in areas like transportations, construction, power generation sectors, rails automobile machine manufacturing and defense integrated antennas (within the soldiers' garment and armors in ballistic protection). In this research work composite material specimens have been developed by hand layup resin transfer molding (HLRTM) system. This HLRTM has been developed locally in the mechanical engineering department. Resin infusion/transfer mold is simple in nature, so that resin can pour into mold at appropriate rate. The fiber material of different orientations o0, 90° and 0190° will be placed in the mold to maintain its orientation; thereafter resin will be transferred to the mold. The test specimens were developed in three groups by changing the orientation of natural fiber whereas resin material vinyl ester was used throughout the development. During test it was found that 0190° orientation of the reinforced material play very important role in the development of composite material. It was observed that the specimens of 0190° orientation possess improved mechanical properties such as tensile [N], Tensile strength a], .MOE [MPa] and Mod,ulus of rigidity [C] over the specimens of 0° and 90° onentat10n as shown in chapter of results and discussion.
