Title:
THREE-DIMENSIONAL WOVEN FABRIC
Document Type and Number:
Japanese Patent JPH04289241
Kind Code:
A
Abstract:

PURPOSE: To improve strength of bonded part (bent part) when three-dimensional woven fabric is used as a skeleton material of composite material of three- dimensional woven fabric in a shape of bonded plural laminar parts such as crossbeam material having a modified section such as L-shaped or U-shaped section.

CONSTITUTION: Three-dimensional woven fabric F is formed into a shape wherein plural laminar parts 1a and 1b are connected in a bent state at a joint part 2, the laminar parts 1a and 1b consist of at least three axes including components in the thickness directions thereof, extend in the directions crossing the joint part 2 of the adjoining laminar parts 1a and 1b, arranged along planes perpendicular to thickness direction of the laminar parts 1a and 1b and have yarn riding the laminar parts 1a and 1b and continuing as a constituent element. Yarn arranged in a state of crossing the joint part effectively contributes to improvement in strength of composite material in such a way that the yarn shares force in a direction to stand stress acting on the joint yarn.
