Embodiment Construction
[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0010] See figure 1 and figure 2 As shown, the present invention is a high-strength, high-modulus and large-size cross-section three-dimensional special-shaped braided reinforcement, which is composed of two kinds of yarns, the dynamic yarn 1 and the static yarn 2, wherein each dynamic yarn 1 is not only wrapped in a spiral A static yarn 2 is wound, and it is also twisted with other closely adjacent dynamic yarns 2, so that the dynamic yarns 1 wrapped around the static yarn 2 are adjacent to each other in a "hand in hand" manner to form a three-dimensional braided reinforcement of the overall structure . The braided body of the present invention can use any one of carbon fiber, aramid fiber, and glass fiber as a raw material.

The present invention discloses a three-dimensional special-shaped weaved reinforcement body with characteristics of high strength, high modulus and large size cross section. The three-dimensional special-shaped weaved reinforcement body comprises two yarns such as moveable yarns (1) and static yarns (2), wherein each moveable yarn (1) wraps a static yarn (2) in a spiral line manner, and forms twisting with other closely adjacent movable yarns (1), such that the moveable yarns wrapping the static yarns (2) form the three-dimensional weaved reinforcement body having the whole structure in a hand-in-hand adjacent connection manner. According to the present invention, the three-dimensional special-shaped weaved reinforcement body with characteristics of high strength and high modulus can be conveniently formed when the moveable yarns do not exist and the tension is difficultly be compensated during large size weaving.
Description
technical field [0001] The invention relates to a braided reinforcement, in particular to a high-strength, high-modulus, large-size, cross-sectional, three-dimensional special-shaped braided reinforcement. Background technique [0002] Currently, the known structures of three-dimensional braids are four-step three-dimensional structures or two-step three-dimensional structures. The former is an interspersed interweaving structure in which dynamic yarns are penetrated in the braiding body, while the latter is a penetrating and interspersed binding structure in which dynamic yarns and static yarns are knitted. Either way, the moving yarn must run through the braid, that is, it must be inserted from one side of the braid to the other. This has brought inevitable following deficiencies: the one, the compensation problem of dynamic yarn tension, especially when the yarn quantity that participates in weaving is bigger. This is because the knitting yarns in the three-dimensional ...
