Preparation and Sound Absorption Property of Al-Si12 Alloy Foam Core Muffler

摘要：

Al-Si12 alloy foams were fabricated by filtration method, and the Al-Sil2 alloy foam core mufflers were made by using the fabricated Al-Si 12 alloy foams. The preparation and sound absorption property of Al-Si 12 alloy foam core muffler has been studied. The results show that sound absorption property of Al-Si 12 alloy foam core muffler increases with the decreasing of pore diameter and the widening of the pore diameter range of Al-Si 12 alloy foam core. Being superior to conventional sound-absorbing materials core mufflers, Al-Si 12 alloy foam core muffler especially fits in noise control in hot, wet, and open-air environments.
