Abstract

The invention discloses a wrapping-pulling woven high-strength composite material tube which comprises a tubular knitting short-cut felt inner-felt wrapping layer, a straight-yarn pultrusion layer, a knitting short-cut felt middle-felt wrapping layer, a high-strength yarn weaving wrapping layer and a knitting short-cut felt outer-felt wrapping layer. The straight-yarn pultrusion layer is wrapped outside the knitting short-cut felt inner-felt wrapping layer, the knitting short-cut felt middle-felt wrapping layer is wrapped outside the straight-yarn pultrusion layer, the high-strength yarn weaving wrapping layer is wound outside the knitting short-cut felt middle-felt wrapping layer, and the knitting short-cut felt outer-felt wrapping layer is wrapped outside the high-strength yarn weaving wrapping layer. The invention has stronger comprehensive performance, high strength, large modulus, high performance resisting cutting and impact damage and good anti-fatigue performance, shock absorption performance and thermal stability performance and is widely suitable for various tent frames.

Description

technical field

[0001] The invention relates to a composite material pipe, in particular to a high-strength composite material pipe which is stretched, braided and wound. Background technique

[0002] A tent is a portable device that mainly provides shelter for outdoor camping, work, etc. A frame tent is a form of tent. The erection process of the existing frame tent is to erect a part of the tent frame and then erect the tarpaulin and finally the tarpaulin is supported together with the tent frame. For the convenience of carrying, the existing tent frame is an aluminum tube. Although this aluminum tube tent frame is light in weight, its strength is not high, and it is often bent or even broken at the support connection between the aluminum tube and the aluminum tube; Metal materials are easily corroded in acid or alkali environments. Contents of the invention

[0003] The purpose of the present invention is to provide a kind of braided and wound high-strength composite...
