| Summary: | Porous aluminium composites are structural and functional materials that have vast potential,
due to their lightweight and high energy absorption capacity, especially in automotive and
aerospace applications. In this study, the effect of varying content of uncoated and Titanium
coated diamond particles on the compressive properties of porous aluminium composite was
investigated. The composites were developed using powder metallurgy technique and porosity
was attained by using polymethylmethacrylate (30 wt.%) as space holder material. The
morphology of the pores was found to replicate the shape and size of polymethylmethacrylate
particles, that were uniformly distributed in the composites. X-ray diffraction analysis
confirmed formation of Aluminium carbide in uncoated diamond-based aluminium composites
while negligible amount was present in titanium coated porous composites during sintering.
The porosities of composites decreased with an increase in diamond content due to the
incomplete decomposition of polymethylmethacrylate particles. Moreover, the maximum
plateau stress and energy absorption capacity of 9.96 MPa and 1.7 Mj/m3 were obtained for the
composites with 8 wt.% of titanium coated diamond particles. Thus, coating inhibits the
formation of undesirable compounds and contributes to better interfacial bonding between
matrix and reinforcement. |
