Abstract :
In this research, closed-cell aluminum foams reinforced by SiC particles were fabricated using direct melt-foaming method and CaCO3 as a blowing agent. The effect of adding reinforcement particles on mechanical properties of foams was investigated by adding different volume percentages of SiC particles (3%, 6%, and 10%). To obtain the mechanical properties of produced foams, uniaxial compression test was carried on samples at different temperature (100°C, 200°C, 300°C, and 400°C) and constant strain rate equal to 0.1s-1. The compression tests result show that at the constant temperature, the yield stress, Plateau stress and energy absorption stresses of composite foams will increase by increasing the volume percentage of SiC particles and decrease with increase in temperature. Reinforcement particles also increase the number of indentation in the stress-strain curve of foams, which reflects increasing brittleness of the foams’ cell wall.
