Abstract
The invention is a composite foam structure comprising a first segment of an anisotropic thermoplastic foam part and a second foam shaped part comprising an isotropic foam wherein the anisotropic foam block and isotropic foam part intersect along at least one common surface.
Claims23
A composite foam structure comprising a first part of an anisotropic thermoplastic foam and a second shaped foam part comprising an isotropic foam wherein the anisotropic foam part and isotropic foam part intersect along at least one common surface.
A composite structure wherein the anisotropic foam part comprises a plurality of oriented strands of foam that are fused together.
An automobile bumper system comprising a bumper beam adapted to be attached to the chassis of a vehicle;
- one or more blocks of anisotropic foam which are attached to the bumper beam wherein the direction of oriented strands of the anisotropic foam blocks is transverse to the longitudinal direction of the bumper beam;
- and a bumper fascia which covers the bumper beam and the composite foam structures so that they are not visible.
