Document Type and Number:
Japanese Patent JPH09176932
Kind Code:
A
Abstract:

To obtain three-dimensional fiber structure so constituted that plural plate-like portions lie continuous in bent fashion at the joint improved in physical properties.

This three-dimensional fiber structure F is formed with the section in nearly L-shaped fashion where two plate-like portions 1a, 1b are mutually jointed in a flexed way through the corner portion 2. The plate-like portions 1a, 1b are each composed of a group of laminated yarns 3 made up of (x)-yarn layers, (y)-yarn layers and bias yarn layers and yarns (z) in the thickness direction mutually binding the respective yarn layers and yarns (c1) and (c2) for both corners. The yarns (z) are arranged in the thickness direction of the fiber structure F rectangularly to the respective yarn layers in the portions other than the corner portion 2 and bind the respective yarn layers. The yarns (c1) the 1st corner are arranged in parallel with the plane dividing the angle made by both the plate-like portions 1a, 1b in half with several numbers of the yarns (c1) arranged symmetrically relative to the plane, while the yarns (c2) for the 2nd corner are arranged rectangularly to the yarns (c1).
