Abstract

Based on the statistic, Malaysian citizen wasted the sources of recycle about RM476 million two years ago. One of the biggest wastes is plastic which contribute 9 percent from the whole waste or RM163 millionthe same situation also occur in Britan where billions of plastic has been throw even for the first time use. One piece of plastic takes 5000 years to decay. This problemindirectly lead to the Global Warming issue that occurs every year. As a solution to reduce the waste of plastic bag, the research entitle ‘Hybrid Composite Using Recycle Plastic Bag’ has been propose. The objectives of this research are to identify and select the best lamination ratio and arrangement for recycle material as well as to study the mechanical properties of the hybrid material. The material has been used in this project are recycle HDPE plastic bag, bamboo, and fibre glass. The recycle plastic bag is used for matrix while the bamboo and fibre glass as a reinforcement in laminate. The hybrid composite is made through the weight percent ratio HDPE:FG:BFPR; 0:100:0, 0.0:100, 100:0:0, 83:0:17,75:7:17, 69:14:17, 62:21:17, 55:28:17. The method approach in this research is by using hot press where the laminate has been heated by assigned temperatures. The mechanical properties has been analysed based on the result obtained from four main testing which are tensile, impact, flexural, and hardness testing. From analysis, this research shows that the bonding of layers in laminate is reinforce by the increasing of fibre glass percent weight. The increasing of fibre glass in composite improves the mechanical properties of composite. Additionally, the selection of laminate is made based of the best mechanical properties obtained from all the testing. This research choose ratio of S/N 6 due to its strong bonding between layers in laminate that leads to the maximum tensile strength, flexural stress, impact strength, and hardness which are 69.53MPa, 54.784MPa,0.123J/mm-2 and 59.3.
