Ultralight, sound and shock absorbing component set

Abstract

The invention relates to an ultralight, sound and shock absorbing component set comprising at least one base layer (2), an intermediate layer (3) and a covering layer (6). The intermediate layer (3) consists of a plurality of hollow bodies (4) arranged next to each other, whose walls are perforated and which thus form a complex labyrinth of hollow spaces. The covering layer (6) preferably has a microporous stiffening layer (8) which generates an airflow resistance of 900 Ns/m3 < Rt < 2000 Ns/m3. The dimensions of the walls of the hollow bodies (4) are such that they allow for compression of at least 50 % at a maximum plateau tension of 0.5 MPa < σ < 1.2 MPa and inelastically and fully convert an impact energy of approximately 0.5 MJ/m3 into deformation work.
