Key words: metal matrix composites; porous material; fly ash; damping properties 1 Introduction The aluminum.... The resonant damping capacity of the ‘porous’ fly ash/6061Al composite reached (20.2-26.9)×10-3 and was about 8 times of the value tested by forced vibration method (in the frequency range 0.2-2 Hz). However......
