Abstract : AD-286 704Div. 14 U (TISTM/ODN) OTS price $1.10 General Dynamics/Convair, San Diego, Calif. TENSILE SHEAR AND PEEL STRENGTH TESTS OF BONDED TEFLON SLIDE BLOCKS FOR SUPERSONIC SEAT, by J. F. Holdener and W. M. Sutherland. 29 June 61, 5p. incl. illus. table (Rept. no. 8926-028) (Contract AF 33(600)36546) Unclassified report DESCRIPTORS: *Adhesives, *Polymers, *Stainless steel, Mechanical properties, Ethylenes, Fluorides, Alloys, Tensile properties, Humid ity, Aging, Epoxy resins, Shear stresses, Coatings, Rubber, Tests, Cadmium plating, Bonding. Identifiers: Teflon. The tensile shear and peel strength of passivated Type 410 stainless steel to caustic etched Teflon to Cd plated 4130 alloy steel composite joints bonded with various adhesives which were cured under various drying conditions was determined both before an after humidity test exposure. As a result of these te ts the Ray Bond R-86004, a 2 component epoxy adhesive, and EC-1751/EC-1752, a two component epoxy adhesive, were shown capable of producing hig bond strengths throughout the variety of curing and humidi y conditions considered. The Eastman No. 910, a proprietary adhesive, Bondmaster M648T, a 2 component epoxy adhesive, EC-1300, a neoprene rubber cement, and Narmco 3119, a 2 component epoxy adhesive, were eliminated because of inadequate tensile shear and peel strength. Continued tensile shear and peel testing with 2024-T4 Alodine 600 coated to Teflon to 2024-T4 Alodine 600 coated composite joints showed the superiority of EC 1751/EC-1752 over the Ray Bond R 86004 adhesive throughout the variety of curing and humidity conditions studied. Shear strengths ranging from 158 to 218 psi and 35 to 65 p/i of width were found with the EC1751/EC-1752 bonded joints. (Author)
