DEVELOPMENT OF NONDESTRUCTIVE TESTS FOR THE EVALUATION OF BONDED MATERIALS.
Abstract
Commercial and military use of adhesive fastening is wisespread and continues to grow rapidly. This growth is indicative of the significant advantages of adhesive bonding over other fastening methods, in that it proceeds in the face of many disadvantages. Current adhesive systems are designed to be forgiving of some latitude in processing, but substandard bonds do occur, and these cannot be tolerated in critical applications. The extent of controls and tests necessary to assure highly reliable adhesive bonds does not appear to be generally appreciated in that many presently available procedures are often ignored. Nondestructive testing can contribute to the production of more reliable adhesive bonds by (1) providing rapid, economical tests for in-process measurement and control to supplement and replace some of the lengthy destructive procedures now required, and (2) providing a non-contaminating means to evaluate the suitability of surfaces for bonding. Based on bonding theory, it appears that this latter may best be done through development of a rapid means to determine the work function of surfaces compatible with production requirements. (Author)
