Abstract
Official abstract text for this publication.
A method of using clear UV protective film for producing a pre-preg carbon fiber part includes pre-applying a clear UV protective film to at least one of a top and bottom surface of a pre-preg carbon fiber workpiece, and placing the pre-preg carbon fiber workpiece between an upper mold portion and a lower mold portion of a hot press molding apparatus. Next, the method includes compressing the pre-preg carbon fiber workpiece between the upper and lower portions of the hot press molding apparatus to form a pre-preg carbon fiber part, and holding the pre-preg carbon fiber part in the hot press molding apparatus until the pre-applied clear UV protective film and the pre-preg carbon fiber part have cured.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of using clear ultra violet (UV) protective film for producing a pre-preg carbon fiber part comprising: pre-applying a clear UV protective film to at least one of a top and bottom surface of a pre-preg carbon fiber workpiece; placing the pre-preg carbon fiber workpiece between an upper mold portion and a lower mold portion of a hot press molding apparatus; compressing the pre-preg carbon fiber workpiece between the upper and lower portions of the hot press molding apparatus to form a pre-preg carbon fiber part; and holding the pre-preg carbon fiber part in the hot press molding apparatus until the pre-applied clear UV protective film and the pre-preg carbon fiber part have cured. 2 . The method of claim 1 wherein the clear UV protective film is urethane based. 3 . The method of claim 1 wherein the clear UV protective film is ionomer based. 4 . The method of claim 1 wherein the clear UV protective film is fluoropolymer based. 5 . The method of claim 1 wherein the clear UV protective film is polycarbonate based. 6 . The method of claim 1 wherein the pre-preg carbon fiber part is a Class A surface part. 7 . The method of claim 1 wherein the pre-preg carbon fiber workpiece is a dry lay up workpiece. 8 . The method of claim 1 wherein the pre-preg carbon fiber workpiece is a wet lay up workpiece. 9 . The method of claim 1 further comprising removing the pre-preg carbon fiber part from the hot press molding apparatus after curing is complete. 10 . A method of using urethane based film for producing a pre-preg carbon fiber part comprising: pre-applying a urethane based film to at least one of a top and bottom surface of a pre-preg carbon fiber workpiece; placing the pre-preg carbon fiber workpiece between an upper mold portion and a lower mold portion of a hot press molding apparatus; compressing the pre-preg carbon fiber workpiece between the upper and lower portions of the hot press molding apparatus to form a pre-preg carbon fiber part; and holding the pre-preg carbon fiber part in the hot press molding apparatus until the pre-applied urethane based film and the pre-preg carbon fiber part have cured. 11 . The method of claim 10 wherein the pre-preg carbon fiber part is a Class A surface part. 12 . The method of claim 10 wherein the pre-preg carbon fiber workpiece is a dry lay up workpiece. 13 . The method of claim 10 wherein the pre-preg carbon fiber workpiece is a wet lay up workpiece. 14 . The method of claim 10 further comprising removing the pre-preg carbon fiber part from the hot press molding apparatus after curing is complete.
