The paper discusses the response to free vibration and also to forced vibration of the A356-SiC AMMCs in the as-cast and T6 temper conditions for the comparative assessment of the damping capacities. The base A356 aluminium alloy and seven A356-SiC composites with SiC percentage ranging from 2% to 12% were stir cast and cantilever specimens of 180 mm length were tested for their frequency and amplitude responses. From the results obtained, it was concluded that the A356-SiC composites with 8% SiC and 3% SiC in the T6 condition could be favourably considered as candidate materials for diesel engine parts in the automotive industry.
