[0024] Below, combine Figure 1 to Figure 4 A first embodiment in which the fiber structure of the present invention is embodied will be described.

[0025] Such as Figure 1 ~ Figure 3 As shown, the fiber structure 10 is formed by laminating the first laminate 13 and the second laminate 20 and combining the first and second laminates 13 and 20 in the lamination direction.

[0026] The first laminated body 13 is a laminated body of two first fiber layers 14 , and is constituted by bonding the two first fiber layers 14 in the lamination direction with the first intermediate weave yarn 16 .

[0027] Each first fiber layer 14 has a plurality of first reinforcing fiber yarns 11 as reinforcing fiber yarns, a plurality of first auxiliary yarns 12 as auxiliary yarns, and a combination of the first reinforcing fiber yarns 11 and the first auxiliary yarns. A plurality of first layer inner weave yarns 15 joined by yarns 12 in the alignment direction. In each first fiber layer 14 , th...

Abstract

Provided is a fiber structure. In a fiber structure, a first laminate and a second laminate are disposed in a state in which the main axes of a first reinforcement fiber yarn and a second reinforcement fiber yarn are caused to be orthogonal and the main axes of a first auxiliary yarn and a second auxiliary yarn are caused to be orthogonal. By the engagement of a first intermediate structure yarn of the first laminate and a second intermediate structure yarn of the second laminate, the first laminate and the second laminate are joined in the lamination direction.

Description

technical field [0001] The present invention relates to a fiber structure composed of a plurality of laminates. Background technique [0002] Fiber-reinforced composites are used as lightweight, high-strength materials. In fiber-reinforced composite materials, reinforcing fibers are compounded with a matrix such as resin or metal. As a result, the mechanical properties (mechanical properties) of the fiber-reinforced composite material are improved compared with the matrix itself. Fiber-reinforced composite materials are therefore preferred as construction components. In particular, when a resin is used as a matrix, it is preferable to reduce the weight of structural parts. [0003] Fiber structures are used as base materials for fiber-reinforced composite materials. As a fiber structure, the yarn main axis of the reinforcing fiber yarn extends in two directions of 0° and 90°, which can improve the mechanical properties of the two directions when used in a fiber-reinforce...
