Polymer hybrid composites have superior mechanical composites such that it can be applied for numerous applications. Hybrid polymers composite suggests the design engineer acquires the significant properties in a significant degree by the selection of fibers and matrix. In the present examination, the mechanical properties of coconut fiber and carbon fibers reinforced polyester hybrid composite were investigated. The basic hand lay-up strategy was utilized for the manufacturing of hybrid composites. The mechanical properties, for example, tensile, flexural, and impact strengths of the hybrid composites were assessed according to the ASTM guidelines. Various proportions of the fibers in the composite specimens with random orientation are tested for the mechanical properties. Examination of treated and untreated fibers was additionally considered to know its effect on the mechanical properties. The mechanical properties were enhanced as the carbon fiber content expanded in the composite specimen.
