Method for making arrow launcher barrel

Abstract

The invention discloses a manufacturing method of a rocket launcher cylinder, which is mainly characterized in that the material of the launcher cylinder includes an ablation-resistant structure layer, a transition structure layer and a strength structure layer. The ablation-resistant structural layer adopts phenolic resin-based ablation-resistant coating as the inner wall of the cylinder, the transitional structural layer is composed of glass fiber non-alkali cloth impregnated with polymer resin, and the strength structural layer is composed of glass fiber non-twisted yarn impregnated with polymer resin constitute. The ablation-resistant structural layer, transitional structural layer, and strength structural layer form a complete composite material through corresponding processes. The launcher cylinder made of this composite material can withstand the overall required destructive strength, and the inner surface is smooth and smooth. The structural size is stable, and it can withstand the ablation and erosion of high-energy propellants when launching rockets multiple times; in addition, it has the advantages of simple structure, light weight, low cost, and convenient maintenance, which fully meets the combat technical index requirements of individual weapon launchers .

Description

technical field [0001] The invention belongs to the technical field of rockets / missiles, and relates to a launcher cylinder capable of launching rockets / missiles multiple times, in particular to a method for manufacturing a composite material launcher cylinder. Background technique [0002] Single-use flechette launcher barrels are typically manufactured from fiberglass reinforced resin-based composites (FRP) by filament winding or roll-to-roll molding. The inner wall of the single-use flechette launcher barrel has no ablation resistant structural layer. The launcher cylinders of my country's Red Arrow-8 anti-tank missile and Red Arrow-9 anti-tank missile weapon system are all made of FRP materials. [0003] Reusable flechette launcher barrels are typically manufactured with resin-based composite reinforced metal liners. In order to ensure that the metal lining of the cylinder does not crack or fall off when rockets (or missiles) are launched multiple times, and to slow do...

AI Technical Summary

Problems solved by technology

However, for the light-duty launcher cylinder used by individual soldiers, if fiber reinforced materials (FRP) are used, when launching rockets, the inner wall of the cylinder does not have an ablation-resistant structural layer and cannot resist the ablation of high-energy propellants. If the metal lining and FRP composite structure are used, although the metal lining can limit the resistance to high-energy emissions The ablation, scouring and repeated use of the drug can meet the requirements of repeated use, but the metal lining will increase the weight of the launcher, which cannot meet the requirements of the individual soldier's portable carrying, and the manufacturing cost is also relatively high.

In addition, during service processing, the metal lining is prone to plastic deformation and bulges inward, which will cause the launcher to be scrapped in severe cases; and the metal lining needs strict anti-rust protection, otherwise serious corrosion will occur, which will cause Increased use and maintenance costs
