Abstract

The purpose of this research is to know the effect of fly ash addition to the hardness and toughness ofmaterial produced. In this research, it is known that aluminum cans waste as a matrix and ash waste coal flyas reinforcement. The tools and materials used in the research are furnace, ladle, stircoast, blower, sand,pattern, waste cans and coal fly ash waste. This research procedure starts from the process of makingspecimens with alloy (%) aluminum-fly ash. Fariation of aluminum-fly ash alloy is 80%: 20%, 70%: 30%,60%: 40%. In Vickers hardness testing seen at the lowest Al-FA hardness level was on specimens withvariation Al 60%: FA 40% ie 49.78528 kg / mm² and highest Al-FA hardness was in specimens withvariation Al 80%: FA 20 % alloy that is equal to 60,25068 kg / mm². Meanwhile, on the toughness impacttest, the highest impact strength value is in Specimens with Al 60% variation: FA 40% alloy is 0.162 J / mm²and the lowest impact strength is in specimen from 100% Aluminum variation of 0.056J / mm².Keywords: Metal matrix composite, Aluminum, and fly ash

Abstract

Composite materials reinforced with natural fibers continue to be developed as alternative materials to replace composite materials. The purpose of this study was to determine the effect of the composition of the matrix, fiber and pokea shell filler on the tensile strength value of the composite polyester resin reinforced with areca nut shell fiber; To determine the effect of the composition of the matrix, fiber and pokea shell filler on the bending strength value of the composite polyester resin reinforced with areca nut shell fiber. Using the Hand Lay Up method, areca nut skin fiber and pokea shell powder filler. Using tensile and bending testing. The results of this study show that the highest average tensile stress is the fraction 70%:20%:10%, the average tensile stress is 13,752 MPa given a force of 1143,687 N. The lowest composite average tensile stress value is the fraction. 70:5%:25% indicates 7,745 MPa. The highest bending test value in the 70%:5%:25% fraction is 35,981 MPa which is given a force of 357,883 N and the lowest average bending stress value is in the 70%:20%:10% fraction of 31,777 MPa given a force of 365,377 N.
