Abstract
This research aims to analyze the effect of a composite of HDPE plastic powder and acid wood powder with a polyester resin matrix on hardness and microstructure tests with a mixture composition of 10% - 20% HDPE plastic powder, 1% - 10% acid wood powder, and 50% polyester resin. -85% composites are made via the hand lay-up method by pouring the material into a mold. The standard size for hardness test specimens uses ASTM D785. The composite hardness test results obtained the highest value for the composition ratio of 85% resin: 14 HDPE plastic powder: 1% acid wood powder, namely 513 HRB, and the lowest value for the mixture ratio of 85% resin: 12% HDPE plastic powder: 3% % acid wood powder with a value of 458.4 HRB. Based on the research results, the average value of hardness strength as HDPE plastic powder increases and acid wood powder decreases, the higher the hardness value. Observation of the micro and macro test structures shows that there are still a few air bubbles in the specimen. By making composites from plastic and wood, excess plastic waste can be reduced. Keywords: Composite, HDPE plastic, polyster resin
