| Summary: | 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. |
