US Patent:

8318296, Nov 27, 2012

Filed:

Feb 21, 2007

Appl. No.:

11/677062

Inventors:

James F. Turnbach - Troy MI, US
David R. Phelps - Ferndale MI, US
Danny Snider - Trenton MI, US

Assignee:

BASF Aktiengesellschaft - Ludwigshafen

International Classification:

B32B 3/02
B32B 27/12

US Classification:

4283044, 428 85, 428 95, 442394

Abstract:

A composite includes a first preform and a second preform spaced from and in overlying relationship to the first preform. The second preform defines at least one first opening extending therethrough along an axis transverse to the first preform. A first surface layer is disposed adjacent to the second preform and on an opposite side of the second preform from the first preform. A polymeric composition including the reaction product of an isocyanate component and an isocyanate-reactive component is disposed between the first preform and the second preform. The polymeric composition adheres the first surface layer to the second preform through the at least one first opening. The surface layer is adhered to the second preform during molding of the composite article and in the absence of additional adhesive, thereby reducing production time and cost of the composite article.
