Abstract
An automotive trim part is provided made of a laminated structure generally consisting of a thermoplastic core layer extruded from at least one feedstock derived from recycled material. The feedstock may consist at least partially of vehicle trim part waste from another vehicle, or trim part waste associated with an automotive trim part the same or similar to the part being produced. The core layer is preferably covered by fibrous layers and may be configured for use at least as a portion of a vehicle's wheel well.
Claims22
An automotive trim part made of a laminated structure comprising:
- a thermoplastic core layer and fibrous cover layers that comprise polyester fibers, whereby the thermoplastic core layer is sandwiched between the fibrous cover layers, and whereby the thermoplastic core layer comprises an extrudate of a mixture of at least:
- feedstock A formed at least partially from ground or shredded trim part waste of a first character, comprising thermoplastic olefin elastomer based materials, and
- feedstock B formed from ground or shredded trim part waste of a second character comprising a laminated structure comprising at least a thermoplastic core panel comprising thermoplastic olefin elastomer and fibrous cover members that include polyester fibers.
An automotive trim part made of a laminated structure comprising:
- a thermoplastic core layer comprising an extruded mixture of two materials obtained from waste materials, comprising:
- a first waste material derived from post consumer materials comprised at least partially of thermoplastic olefin elastomer, a polyester fiber filler, and an inert filler, and
- a second waste material derived from automotive trim part waste comprised of a laminated structure consisting of a thermoplastic core panel comprising thermoplastic olefin elastomer and fibrous cover members that include polyester fibers that has been ground, shredded, or otherwise separated.
An automotive trim part made of a laminated structure comprising:
- an extruded thermoplastic core layer formed from a mixture of at least
- a first feedstock formed from ground or shredded waste derived from post-consumer materials comprising:
- a blend of thermoplastic polyolefin elastomeric material comprised of:
- polypropylene-ethylene propylene diene monomer (PP-EPDM),
- a polyester fiber filler, and
- an inert filler,
- a second feedstock derived from automotive trim part waste that has been ground or shredded, fibrous material;
- and
- first and second polyester fibrous cover layers, wherein the thermoplastic core layer is sandwiched between the first and second fibrous cover layers.
