High thermal conductivity is one important factor in the selection or development of ceramics or composite materials. Predicting the thermal conductivity would be useful to the design and application of such materials. In this paper, a multi-scale model is developed to predict the effective thermal conductivity in SiC particle-reinforced aluminum metal matrix composite. A coupled two-temperature molecular dynamics model is used to calculate the thermal conductivity of the Al/SiC interface. The electronic effects on the interfacial thermal conductivity are studied. A homogenized finite element model with embedded thin interfacial elements is used to predict the properties of bulk materials, considering the microstructure. The effects of temperatures, SiC particle sizes, and volume fractions on the thermal conductivity are also studied. A good agreement is found between prediction results and experimental measurements. The successful prediction of thermal conductivity could help a better understanding and an improvement of thermal transport within composites and ceramics.

In this present paper, the friction and wear performances of Al-SiC metal matrix composite (MMC) for varying operating parameters (applied load and sliding speed) have been studied under acidic environment. The composite material is developed by reinforcing SiC particle (5 wt. %) with aluminum alloy (LM6) using stir casting method. The tribological behavior is performed using a friction and wear monitor under sulphuric acid environment where sliding time is kept constant for 30 minutes. It is found that wear is directly proportional to the applied normal load and sliding speed. Coefficient of friction value decreases with increase in load but remains almost constant with variation of sliding speed. The surface morphology is studied with the help of scanning electron microscopy (SEM) and energy dispersed X-ray (EDX) analysis.
