Method Of Forming Lamina And Block Laminates
US Patent:
4182641, Jan 8, 1980
Filed:
Apr 21, 1978
Appl. No.:
5/898871
Inventors:
Martin E. Fitts - Portland OR
Assignee:
Core-Lock Foam, Inc. - Bend OR
International Classification:
B32B 518
US Classification:
156 77
Abstract:
A method of forming a laminate composed of a solid polyester lamina bonded to a block. A block having a matrix composed of polyurethane foam and particles of expanded polystyrene distributed therein is prepared. A layer composed of a solution of a relatively unpolymerized polyester in styrene solvent with fiberglass embedded therein is placed in contact with a surface of the block. The styrene solution of polyester dissolves polystyrene particles adjacent such block surface, leaving recesses distributed in the block matrix. These recesses become at least partially filled with the polyester solution. The solution is then cured to produce a solid resin lamina which is joined with polymerized resin contained in the matrix recesses to secure the lamina to the block.
