Abstract

This research is important to human being because a global reduction of CO2 emissions is becoming more and more important to prevent global warming caused by green-house gas production. So, recycling of aluminium alloy scraps is important to reduce energy consumption and also a reduction of CO2 emissions in manufacturing processes. The main purpose of this research is to determine the effect of Aluminium Alloy AA6061chips sizes and composition of polycarbonate on mechanical strength prepared by compaction process. Besides that, to investigate the effect of pressure and time compacted on mechanical properties. The research was conducted with different chips size, different composition of binder, different pressure and difference time throughout compacted process. Three difference chips sizes are selected which is 250, 500, and 710 μm, different pressure is 0.5, 1.0 and 2 tonne, meanwhile for different time compaction is 20, 30 and 40 minutes. From the result obtained, the highest strength showed by sample with chips size 250 μm and composition of polycarbonate 30 wt% with value 61.185 MPa. Furthermore for higher hardness also at the lowest chips size 250 μm and higher composition of polycarbonate 30 wt% with 167.752 HV. Meanwhile for the lowest values of strength and hardness are 6.7894 MPa and 72.2052 HV at chips size 710 μm and 10 wt% of polycarbonate. In this research, lower chip sizes, addition of composition polycarbonate, higher pressure and time compaction could improve the mechanical strength of Aluminium Alloy waste chips.
