摘要

This current work have investigated the mechanical properties of a polymer composite hybridized with particulate rice husk (PRH) and particulate carbon fibre (PCF). The hand lay-up fabrication process is adopted to develop the composite. Mechanical properties such as compressive strength, tensile strength, and flexural bending strength of the developed hybrid polymer composite, and composites with single fillers at different weight percentages of PRH and PCF, are analysed through the experimental program. It is observed from the experiments that both types of composites exhibit low mechanical strength in tension, but demonstrate good strength in both compression and bending. Furthermore, it is noted that the hybrid composite containing 5% weight of PRH and 5% weight of PCF exhibits superior mechanical properties in tension, compression, and bending compared to other compositions. The corresponding values are 17.89 MPa, 93.84 MPa, and 114 N, respectively. Scanning electron microscope (SEM) surface morphology analysis reveals that the tensile and bending fractures of the composite are of a brittle type.
