Abstract
The invention relates to an ultralight, sound and shock absorbing component set comprising at least one base layer ( ), an intermediate layer ( ) and a covering layer ( ). The intermediate layer ( ) consists of a plurality of hollow bodies ( ) arranged next to each other, whose walls are perforated and which thus form a complex labyrinth of hollow spaces. The covering layer ( ) preferably has a microporous stiffening layer ( ) which generates an airflow resistance of 900 Ns/m <R <2000 Ns/m . The dimensions of the walls of the hollow bodies ( ) are such that they allow for compression of at least 50% at a maximum plateau tension of 0.5 Mpa<&sgr;<1.2 Mpa and inelastically and fully convert an impact energy of approximately 0.5 MJ/m into deformation work.
