Composite chamber case of Φ200 mm solid-rocket motor was made by using the two kinds of epoxy
resins E-51 and TDE-85, as well as molding process of hermetic and heat-resistance material and molding process of
filament winding composites were adopted. The PV / W values of the finished Φ200 mm case are 32. 3 km. The hydrostatic
burst test of 36 MPa show that the performances of the filament winding case of solid-rocket motor meet the design
requirements.
