A low-cost process for the primary roll diffusion bonding of boron-aluminum monotapes and multi-ply panels in air was developed. Heating was performed in either air or argon with properties equivalent to higher cost vacuum and press bonded material. The average tensile strengths of roll bonded monotapes was 207 KSI with secondary press bonded panel strengths being 201 KSI longitudinal and 19 KSI transverse. Panels containing interleaved titanium foil of 18-26 volume percent were produced by primary and secondary roll bonding with 200 KSI longitudinal and 46-70 KSI transverse strengths. Cost projections indicate processing costs of 40, 19, and 13lb for boron-aluminum monotape at an annual production volume of 2,000, 20,000 and 200,000 pounds.
