Abstract:

I DENTIFIERS Spiral wrap, Mandrels. Progr ss is reported on 1 the fabrication of 18 steel AM 355 tubular specimens and testing of units for aging and vibration, 2 fabrication and testing of 118 uniaxial tensile and flexural specimens for establishment of design values, and 3 fabrication and testing of 20and 40-in.-fism Ti strip specimens. Tooling design and fabrication is evaluated as it relates to 20-in. diam specimens and how it will affect the 40-in. diam tooling. A portion of the end closure design work is presented. The design of helically wound tube sections should incorporate the greatest possible number of tallic layers to utilize the maximum strength in the metal. Rolled and welded Al plate should be considered for helically wound tube mandrels. Restraining the tubular specimens during cure of the adhesive should eliminate the problem of machi i g inside bore of the restraining device and reduce the mass of metal which must be heated to effect adhesive cure.
