Abstract : Test data compiled under TR 45-157.02 indicated that the corner couch specimens fabricated from production parts (Metal-to-laminate configuration) are not developing expected strengths. This test program was initiated to compare the previously compiled data and to obtain data on alternate cleaning procedures and bonding materials to be used. Tensile lap-shear strengths were determined for several metal-tometal and metal-to-laminate bonding configurations and two cleaning procedures were investigated. A comparison of the results obtaineuefrom TR 45-157.02 and this test request revealed that bond strengths obtained from specimens fabricated from production parts were abnormally low. AF 106 adhesive used in conjunction with cleaning procedures (MAC PS 14020) is recommended for bonding aluminum to aluminum and aluminum to F-141 prepreg. Also, FM 99 adhesive used in conjunction with cleaning procedure MAC PS (11308) is recommended for bonding aluminum to polyester laminate. (Author)
