Theoretical analyses and hypotheses, and tests are presented for the determination of the adaptability and advantage of utilizing wire in rocket motor case and pressure vessel construction. A review was made of wire manufacturingAND HIGH STRENGTH AND STRENGTHWEIGHT MATERIALS WERE SELECTED AND TESTED. Steel wire had the highest strength 585,000 psi, 0.004-in. diameter with a strengthweight of about 2 million inches beta Ti wire had a strengthweight of 1,950,000 inches. These 2 wires approached the strengthweight of glass filaments 2 to 2.5 million inches. Tests conducted on the effect of wire handling in the processing stage of product manufacturing indicated that the loss of wire strength due to handling and spooling was not a major problem. An estimate made of the projected strength of wire over the next several years indicated steel wire outside fiber strengths of 1 million psi.
