MANUFACTURING METHOD OF COMPOSITE FOR SOLID PROPELLANT AND COMPOSITE FOR SOLID PROPELLANT BY THE METHOD

摘要

The present invention relates to a method for producing a solid propellant composition and a solid propellant composition prepared by the method, and the raw materials for producing the solid propellant are divided and injected into a vacuum mixer, and a vacuum mixing process is performed between each injection step, and a curing agent is added. After injecting the last of the raw materials, the final vacuum mixing process is carried out to lower the viscosity of the propellant to prevent defects such as pores or cracks in the manufactured solid propellant, improve the quality of the solid propellant, and to improve the quality of the solid propellant. It enables stable solid propellant operation by preventing rocket explosion accidents caused by
