Embodiment 1

[0019] This embodiment is a conical integral fabric reinforcement with a square top, which is integrally and coherently formed by two parts, the top and the body.

[0020] The top structure of this embodiment is a 5-layer fabric with an overall structure composed of 5 sub-layer fabrics L1, L2, L3, L4, and L5 in thickness, which is to connect 2 layers and above sub-layers by connecting warp yarns in the thickness direction of the fabric. The multi-layer woven fabric is formed by connecting the fabric as a whole, so that the connecting warp yarn is only between two adjacent sub-layer fabrics, and is superimposed with the warp yarn of the sub-layer fabric in the same longitudinal direction in the width direction of the fabric. The way in the cross-section is to realize the connection of the adjacent sub-layer fabrics.

[0021] The top structure can be detailed with figure 1 , 2 , 3 to illustrate the narrative. In the figure, y and z are the length and thickness directions of t...

Abstract

The invention relates to a conical whole textile reinforcing body which is formed by a top part and a body part in a whole consistent mode. Structure of the top part of the conical whole textile reinforcing body is made of a multilayer woven fabric connect connected by coinciding layer and layer through warps. The connecting warps are only arranged between two neighboring layers of sublayers fabric, and achieving connecting of the adjacent layers of sublayers fabric by coinciding with the sublayers fabric in a same longitudinal cross section in a fabric width direction. Due to mutual structural independence of the sublayers, when a superficial layer is damaged, destruction on the top part is not prone to spread to inner layers, and the inner layers still have structural integrity, and thus the conical whole textile reinforcing body can resist abrasion and ablation, and can be widely applied to fields of aviation, aerospace, weapon, civilian use and the like.

Description

Technical field [0001] The invention relates to a conical integral fabric reinforcement, in particular to a conical integral fabric reinforcement with a top formed of multi-layer woven fabrics. Background technique [0002] The conical integral fabric reinforcement is a special-shaped fabric, which is special in shape, and usually has a cap at one end; an example of its common use is that the three-dimensional rotary shell fabric woven with carbon fiber is made into a C / C composite material after carburizing Compared with traditional metal parts, the casing has a good weight reduction effect, and various properties can meet the requirements at the same time. It is widely used in the field of aerospace, especially in solid rocket motor composite casings. [0003] An ideal conical integral fabric reinforcement should be able to meet the following structural and performance requirements: in terms of structural composition, the top and body are a continuous integral structure, w...
