Abstract

Hybrid composites are having the greatest potential for engineers in many applications. A hybrid polymer composite offers the designer to obtain the necessary properties to a substantial extent by the choice of fibers and matrix. In the present investigation, the mechanical properties of carbon and grass fibers reinforced polyester hybrid composite were studied. The hand lay up technique was used for the fabrication of hybrid composites. The mechanical properties such as tensile strength, flexural strength and impact strength of the hybrid composites were evaluated as per the ASTM standards. The variation of mechanical properties such as tensile, flexural and impact properties of randomly oriented polyester based grass/carbon fiber reinforced hybrid composites with different fiber weight ratios have been studied. Comparison of treated and untreated fibers was also studied. The mechanical properties were improved as the carbon fiber content increased in the matrix material.
