Claim 2
Dependent Claim
53 words
A composite article comprising a core of fiberglass mattes impregnated with a thermoplastic resin binder having adjacent to one or more of said matte's edges a strip of semi-rigid urethane foam and having one or more reinforcing layers bonded to at least one of the core surfaces to form a unitary composite article.
Claim 3
Dependent Claim
18 words
The composite article of claim 1 wherein the semi-rigid urethane foam surrounds the edges of the core structure.
Claim 4
Dependent Claim
27 words
The composite article of claim 1 wherein the semi-rigid urethane foam strip has a thickness greater than 7 mm and a width of greater than 1 inch.
Claim 5
Dependent Claim
16 words

Claim 8
Dependent Claim
13 words
The composite article of claim 6 wherein the decorative layer is foam backed.
Claim 9
Dependent Claim
46 words
A composite article useful as an automobile interior trim panel comprising a core structure of resin impregnated fiberglass, the edges of which are surrounded with a semi-rigid thermoformable urethane wherein said top and or bottom of said core has one or more reinforcing layers bonded thereto.
Claim 10
Dependent Claim
46 words
A composite article useful as an automobile interior trim panel comprising a core structure of resin impregnated fiberglass, the edges of which are surrounded with a semi-rigid thermoformable urethane wherein said top and or bottom of said core has one or more reinforcing layers bonded thereto.
Claim 11
Dependent Claim
74 words
A composite preform comprising a flat core of fiberglass impregnated with a thermoplastic resin having adjacent to one or more of said matte's edges a strip of thermoformable semi-rigid urethane foam, a layer of adhesive on at least one surface of said core and one or more reinforcing layers positioned on the core surfaces having the adhesive layer, said preform capable of being formed into a unitary composite article under sufficient heat and pressure.
Claim 12
Dependent Claim
74 words
A composite preform comprising a flat core of fiberglass impregnated with a thermoplastic resin having adjacent to one or more of said matte's edges a strip of thermoformable semi-rigid urethane foam, a layer of adhesive on at least one surface of said core and one or more reinforcing layers positioned on the core surfaces having the adhesive layer, said preform capable of being formed into a unitary composite article under sufficient heat and pressure.
