Title:
MANUFACTURE OF THREE-DIMENSIONAL FABRIC FOR FIBER REINFORCED COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JP2000202931
Kind Code:
A
Abstract:

To apply this manufacturing method in both a rectangular co-ordinate system and a cylindrical co-ordinate system so as to nearly uniformly enhance the whole fiber density.

A fiber layer is formed by densely arranging low sizing fibers having the low weight percentage of a resin each other. By laminating fiber layers to one another in such a fashion that fibers intersect with each other and compressing the resultant laminated fiber layers, the low sizing fibers are deformed in a near rectangle. In addition, z-diretional fibers 3 are passed normal to the fiber layer. Further, in case of a cylindrical co-ordinate system three dimensional fabric, among the fibers in the outside portion of radially extending r-directional fibers 1, other r-directional fibers 1a and 1b are densely inserted so as to form the r-directional fibers. These r-directional fiber layers and θ-directional fiber layers consisting of annularly extending θ-directional low sizing fibers are piled up each other. Especially, by setting the weight percentage of the resin of the low sizing fiber of 1% or less, the width of the fiber of 1-2 mm and the width of the fiber of 0.7 times as much as the interval between the fibers, the fiber volumetric percentage of about 40% or more of the fabric can be obtained.
