GLASS-FIBER THERMAL-INSULATION SOUND ABSORBING BODY AND USAGE THEREOF

摘要

A glass-fiber thermal-insulation sound absorbing body (1) according to the present invention is provided with a flexible part (2) and a high-rigidity part (3) that are molded by intertwining a plurality of glass fibers and that are stacked on each other; the density of the flexible part (2) is greater than 80 kg/m3 and equal to or less than 100 kg/m3; and the density of the high-rigidity part (3) ranges from 120 kg/m3 to 300 kg/m3, and the bending elastic modulus thereof ranges from 150 MPa to 500 MPa.
