EFFECT OF TESTING VARIABLES ON TENSILE SHEAR STRENGTH
Abstract
Metlbond 4021 tape was tested to determine the effects of (1) relative atmospheric humidity; (2) rate of loading test specimens; (3)removal of excess test specimen flash; (4) bonding press pre-heating; and time lapse from bonding to testing. Tapes which were subjected to high relative humidity showed decreased tensile shear strength. Strength increases appeared to increase when testing speeds were doubled. Flash removal enhanced tensile shear strength results. No significant differences in test result occurred between tests prepared with cold or pre-heated presses. Time lapse variations between curing and testing were not significant in test results.
