Title:
PRODUCTION OF ISOTROPIC THREE-DIMENSIONAL WOVEN PREFORM AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JPH0892843
Kind Code:
A
Abstract:

PURPOSE: To obtain a three-dimensional woven preform capable of imparting diversity to the change in the thickness of a rod as a problem on the production of a rod type three-dimensional three axial woven fabric, capable of changing the arrangement ratios of fibers so as to be different in the three axial directions, and capable expressing mechanical or thermal isotropy.

CONSTITUTION: When a three-dimensional three-axial preform arranged and woven in the mutually orthogonal three directions is produced with rods, rods 1, 2 having a standard thickness are used in the X and Y directions, and rods 3 having a side length of several times the side length of the cross section of the rod used in the X and Y directions is used in the Z direction. The rods in the Z direction are arranged in parallel to each other at an interval corresponding the thickness of the rod in the X and Y directions, and the rods in the X and Y directions are inserted with an insertion means for standard rods inserting at an interval corresponding to this thickness, while only parts for the insertion of the rods by the insertion means are selectively operated.
