MOUNTING ASSEMBLY HAVING SOUND AND IMPACT ABSORBING PROPERTY, SUPER-LIGHT STRUCTURE SET AND USAGE OF MOUNTING ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a thin and super-light decorated structural member having sound and impact absorbing property.;SOLUTION: The super-light structure set having sound and impact absorbing property comprises, at least, a base layer 2, an intermediate layer 3 and a coating layer 6. The intermediate layer 3 consists of a plurality of hollow bodies 4 arranged in parallel to one another and having pierced walls to form complicated labyrinths in a hollow space. The coating layer 6 has a micro-cavity hardened layer 8 to allow an air flow resistance to be preferably 900Ns/m³Rt2000Ns/m³. The walls of the hollow bodies 4 are dimensionally compressed and deformed at least 50% when the maximum plateau stress of 0.5MPaσ1.2MPs exists, which converts non-elastically and completely impact energy of about 0.5MJ/m³ into deforming operation.;COPYRIGHT: (C)2004,JPO&NCIPI
