DEVELOPMENT OF IMPROVED HIGH-STRENGTH PREIMPREGNATED MATERIALS FOR FILAMENT-WOUND ROCKET MOTOR CASES

Abstract

Fifteen spools of 20-end, no-end-out, PO 48 finish, glass roving from Lot 37 were selecte AT RANDOM FOR USE AS PRODUCTION CONTROL STANDAR S. An average ultimate tensile strength of 311,000 psi was obtained on specimens of this material. The loss on ignition (average 1.21%), with the exception of one spool, was within the specified range of 1.5 + or - 0.5%. The average weight of glass roving per yard was 0.628 g with less than 3% variation. NOL ring specimens and an 18-in.-diam Polaris boss chamber were fab icated by wet winding techniques. The chamber failed at a burst pressure of 866 psig with hoop filament stress of 305,900 psi.
