摘要
The present invention relates to a method for manufacturing an integrated nozzle for a rocket propulsion engine in which a nozzle heat resistant material containing a phenol compound material is integrally molded, and more particularly to a method for manufacturing an integral nozzle for a rocket propulsion engine comprising 20 to 25% by weight of a phenol resin, A raw material mixing step of mixing a raw material for a nozzle heat resistant material comprising 30 wt% of graphite powder, 2 to 5 wt% of graphite powder, 10 to 15 wt% of mica, 15 to 8 wt% of silicon carbide, and 15 to 10 wt% of a curing agent, Placing a nozzle enclosure in a molding space of the preheated mold and injecting the mixture in a predetermined amount; applying heat and pressure to the mold to apply heat to the nozzle outer surface of the outer surface of the nozzle enclosure An integral nozzle forming step in which the ash is integrally formed and a desalting step in which the formed integral nozzle is desorbed from the mold Such a nozzle manufacturing method of the present invention can manufacture a nozzle having a simple manufacturing process, a low cost, a high heat resistance and a high mechanical strength, compared with a general composite nozzle material in a conventional solid rocket propulsion engine .
