Abstract
Generally, composite material is a material made from two or more constituent materials of different properties. Composite materials are highly utilized in the current era due to their tailored specified properties, such as high strength-to-weight, corrosion resistance, inflammable properties, wear resistance and etc. In this study, mechanical properties of bio composite materials, such as coir, and palm oil fibre, are to be analysed and evaluated thoroughly. Fabrication methods, such as compression moulding and resin film infusion method were used to manufacture the specimens for the test and analysis. Impact test, tensile test, and compression test were carried out simultaneously during analysis and evaluation process. The results from tensile, compression and impact testing were tabulated and plotted into graphs for analysis. Bar charts which include specific mechanical properties were plotted to compare the properties of the composites (GFRC, HPRC, HCRC, PFRC, CFRC). Moreover, hybridization of natural fibre has shown significant increase in tensile and impact testing, whereas for compression testing, no significant change was identified. Eventually, a crash resistance car bumper will be developed based on these bio composite and hybrids.
