Research on Dry Winding Forming Technology for Solid Rocket Engine Shell
Compared to traditional wet winding molding technology,dry winding has a clean environment and no resin pollution,which can solve the problem of manual processing,improve production efficiency,accurately control the resin content,improve the reliability of product quality,and have many advantages.It is expected to become the mainstreamof future solid rocket engine composite material shell winding molding technology.This article uses the prepreg silk of T700 as the raw material to prepare unidirectional plate and NOL ring samples through dry winding.Compared with wet winding samples,the tensile performance is inferior,but the interlayer shear strength is superior.Finally,dry winding was applied on the solid scaled engine shell,and burst pressure of the shell reached 12.15MPa,with a fiber strength utilization rate of 85％.
