Abstract
A novel porous laminated composite material (PLCM), made of polymer, metal, and polymer fibers with low melting point, is developed. Manufactured by the premix, lamination, preheating, and molded tech niques, the proposed PLCM exhibits very high sound absorption coefficient in the frequency range of 500 to 2000 Hz with a relatively thin and light structure. Using a porous rigid body, a mathematical model, charac terized by five macroscopic...
