A carbon braided and wound carbon fiber launch tube and its manufacturing method

Abstract

The invention discloses a method for manufacturing a carbon weaving and winding carbon fiber launch tube, which includes 1) preparing an integrated device for winding and weaving and an elliptical stainless steel cylinder as a mould; 2) preparing fibers and resin; 3) designing the structure of the launch tube; 4) Step-by-step layup of the five-section area; 5) Put the mold and the launch tube together into the oven for post-curing treatment; 6) After the curing is completed, perform mechanical processing according to the design drawings to obtain the net size of the product; a carbon weaving and winding carbon fiber The launch tube is divided into five sections. The length of the rear section of the launch tube is 600mm shorter than the length of the previous section. The latter section covers the previous section. The section of the launch tube is elliptical. The invention reduces the amount of raw materials used, thereby greatly reducing the weight of the launch tube and reducing the cost; effectively combining the traditional wet winding machine with the rotary net knitting machine, the utilization rate of the two devices has been improved, Thereby reducing the production cost.

Description

Technical field [0001] The present invention relates to the field of launching tubes, and more particularly to a carbon woven-wound carbon fiber emitter and a method of manufacturing the same. Background technique [0002] The transmit tube is used to transmit the outer tube of certain moving devices, and the small emission tube has a serveometer outer tube, a fishing tube, a large launch pipe, a missile launch tube, a missile launch tube, a rocket launch tube, and the like. Most of the materials of most launch tubes are all combined with alloy steels, often in medium carbon nickel-chromium platinum steel, and there are small amounts of vanadium to modify steel. In order to mitigate the weight of the transmit tube, the recent starting of a large number of organic composite launch tubes is started. Since the maximum temperature resistance of the organic composite material is difficult to exceed 400 ° C. Therefore, most of the forms of metal and organic composites are still used to...

AI Technical Summary

Problems solved by technology

The biggest problem with wet winding is that it is difficult to wind at small angles (winding tension at small angles is difficult to guarantee). In order to ensure the stiffness in the length direction of the launch tube, it is necessary to double or even triple the amount of winding at a large angle to ensure the stiffness in the length direction. The wall thickness of the launch tube is greatly increased, so it is difficult to reduce the weight
