Title:
THREE-DIMENSIONAL WOVEN FABRIC
Document Type and Number:
Japanese Patent JPH0559634
Kind Code:
A
Abstract:

PURPOSE: To obtain a three-dimensional woven fabric capable of enhancing strength in connected parts readily causing stress concentration and improving fastness (durability) for tensile and compressive loads in its use as a skeletal material in composite materials of a shape in which plural platy parts are joined such as beam materials of modified cross section in the shape of L, U, etc.

CONSTITUTION: Plural platy parts (1a) and (1b) are formed into a continuous shape through a curved part 2. In the respective platy parts (1a) and (1b), yarn layers composed of yarn, laminated into many layers in the platy parts and oriented in at least two direction are connected with yarn (z) in the thickness direction inserted in a folded back form in the thickness direction of the yarn layers. The curved part 2 is constructed of yarn layers composed of in-plane oriented yarns oriented in a continuous state straddling the adjacent platy parts (1a) and (1b) and rods (zr) as yarn in a component in the thickness direction oriented in the unfolded back state in the thickness direction of the curved part 2.
