Title:
USE OF MICROWAVE ENERGY TO AID IN ALTERING THE SHAPE AND IN POST-PRODUCTION PROCESSING OF FIBER-REINFORCED COMPOSITES
Document Type and Number:
WIPO Patent Application WO2004009646
Kind Code:
A3
Abstract:
A method for preparing a fiber reinforced composite (10) that has a surprisingly high absorption of microwave energy and subjecting the composite to microwave energy to sufficiently depolymerize the matrix material (14) of the composite to selectively alter the shape (16) of the article. The composite has an absorption of microwaves that is between 2 and 20 times greater than that of conventional composites.
