Development of High Temperature Addition-Cured Adhesives
Abstract
An evaluation of two high-temperature addition-cured adhesives. These were (1) NITRILE SUBSTITUTED POLYPHENYL ETHERS CURED WITH TERPHTHALONITRILE N, N-dioxide (TPNO) AND (2) acetylene termin-ated polyimide (HR600) cured thermally. The thermally cured acetylene terminated polyimide proved to be superior to the TPNO cured cyano substituted polyphenylene oxide. Lap-shear strengths of 6A14V titanium bonded with HR600 adhesive exceeded 3000 psi at ambient temperature on powdered aluminum-filled specimens reinforced with heat cleaned 112 glass fabric and 2800 psi at ambient temperature, 2600 psi at 450^F and 2100 psi at 500^F on unfilled specimens bonded with 70 percent HR600 prepreg on 112 heat cleaned glass fabric. Weld-bonding of titanium specimens using aluminum powder filled HR600 adhesive proved to be successful and showed superior fatigue resistance over spot-welded specimens.
