The objectives of the study program were to study the effects of surface flaws on the performance of Polaris fila ment-wound motor cases, to compare the effect of winding sequence on the ability to resist failure from surface flaws, and to determine the feasibility of various repair techniques. These objectives were accomplished through the fabrication, machine flawing, and hydrotesting of 6- and 18-inch diameter filament-wound bottles. The bottles were fabricated with WS-1028A preimpregnated glass roving, and the wall thicknesses wre similar to the full-scale Polaris A-3 first- and second-stage motor cases. Author
