Title:
PRODUCTION OF PREFORM OF THREE-DIMENSIONAL WOVEN FABRIC FOR COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JPH0578948
Kind Code:
A
Abstract:

PURPOSE: To contrive the remarkable improvement in the productivity of a large three-dimensional composite article by forming reinforcing fiber bundles and the primary matrix having an excellent rod-forming property into rods, weaving the rods into a three-dimensional woven fabric preform and subsequently removing the primary matrix from the preform.

CONSTITUTION: Rods are formed from reinforcing fiber bundles such as carbon fibers and the primary matrix such as an unsaturated polyester resin, a vinyl ester resin, a methyl methacrylate resin, an acrylate resin or a monomer, the primary matrix being selected on the consideration of its rod-forming property regardless of the matrix of the final composite article. The rods are woven into a three-dimensional woven fabric preform, and the primary matrix is chemically decomposed or dissolved off in the state holding the shape of the preform. The resulting preform is impregnated with the final objective secondary matrix to obtain a prescribed three-dimensional woven fabric composite article.
