ULTRALIGHT, SOUND AND SHOCK ABSORBING COMPONENT SET |
| 摘要 |
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<sigma<1.2 Mpa and inelastically and fully convert an impact energy of approximately 0.5 MJ/m3 into deformation work. |
