Abstract

Low Density Polytehylene (LDPE) is known as a low cost engineering plastics with its outstanding properties. It has been widely used in various industries. Glass fibre (GF) is one of the well-known reinforcing agents. This research is conducted to study the mechanical and thermal properties of GF reinforced LDPE. The mix formulations used for the GF reinforced LDPE are 10% wt GF, 15% wt GF and 20% wt GF by using compression moulding. By increasing the weight percentage of GF, the tensile strength of the composite was found to be increased. However, the percentage of elongation at break displayed an inverse pattern. Besides, analysis of thermal properties showed that the thermal degradation temperature and degree of crystallinity was increased with the weight percentage of GF. 20 wt% GF reinforced LDPE exhibited the highest tensile strength and thermal degradation temperature. In addition, the fracture surface morphology of each samples were obtained. It showed that with higher weight percentage of GF had less void content and performs less plastically deformed. Hence, it could be concluded that the objectives of this project were achieved where the mechanical and thermal properties of GF reinforced LDPE were studied. It was shown that there were improvements on LDPE’s mechanical and thermal properties by reinforcing with GF.
