Abstract
A panel of perforated thermoplastic material having sound and shock dampening characteristics comprised of a perforated honeycomb core and either whole or perforated facing sheets, thermal compression bonded to the core. The core can be faced on one side only, or on both sides to create a pad or panel of such material.
Claims9
A honeycomb panel having anisotropic flexing characteristics for dampening or dissipating pressure forces or waves, comprising:
- a honeycomb core formed of undulated strips of resilient, thermoplastic material, thermal compression bonded together to form cell walls defining a plurality of contiguous regularly shaped cells, the walls of which have a plurality of perforations;
- a first facing sheet of said resilient thermoplastic material, thermal compression bonded to an upper surface of said core formed by the upper extremities of said cell walls, the bonding being accomplished by simultaneously applying heat and pressure to the joinder of said first facing sheet and said core;
- and
- a second facing sheet of said resilient thermoplastic material, thermal compression bonded to a lower surface of said core formed by the lower extremities of said cell walls, the bonding being accomplished by simultaneously applying heat and pressure to the joinder of said second facing sheet and said core.
