Adhesive Evaluation of Thin Films of LARC-TPI and LARC-TPI with 5 MOL percent ODA.

Abstract

A commercially available LARC-TPI film and an experimentally prepared film of LARC-TPI with 5 mcl % of 4,4'-oxydianiline (ODA), designated as LARC-TPI/O!)A in the report, supplied by Mitsui Toatsu Chemicals, Incorporated (TPI), Japan, were evaluated as thermoplastic adhesive films for bonding Ti-6Al-4V. The LARC-TPI/ODA had been shown by MTCI to possess more flow than thermoplastic LARC-TPI and was, therefore, evaluated and compared to the LARC-TPI. Lap shear strength was used to evaluate the materials as adhesives. They were characterized after fracture by determining the glass transition temperature, Tg. The mode of failure was also reported. Thermal exposure at 204C for 500 and 1000 hrs and a 72-hour water-hoil were conducted on lap shear specimens prepared with the two adhesive films. Lap shear tests were conducted at RT, 177C, 204C, and 232C before and after exposures. (AN)
