Abstract

Homogeneity of SiC particle distribution was investigated for Al/SiC and Al/Al2O3 laminate hybrid composites system. The volume fraction of SiC used various from 10, 20, 30 to 40%Vf while %Vf Al 2O3 was kept constant. All samples then were sintered at temperature of 600°C for 6 hours in the vacuum furnace. Bending test was observed to determine the effect of SiC on the interface bonding between Al/SiC-Al/Al2O3 laminate hybrid composites. It is found that increasing of volume fraction and homogeneity of SiC distribution, modulus of elasticity are also increase. These are correlated to increase bonding strength of interface between Al/SiC-Al/Al2O3 laminate hybrid composites. Modulus of elasticity of laminate hybrid composites increased from 120,98 GPa for 10%Vf SiC to 157,81GPa for 40 %Vf SiC. Surface roughness of the reinforcing material and surface layer improves the mechanical interlocking at the interface. Microstructure analysis in the interface was analyzed by SEM confirm that there is some of reinforcement clustering occurs and decrease the bending strength of composite. However, homogeneity distribution SiC particle enhanced mechanical properties of laminate hybrid composite.
