NDE Objectives

  • Develop nondestructive inspection (NDI) methods for adhesive bond evaluation that can be used in an automotive manufacturing environment to foster increased confidence and use of adhesive joining. Impetus: The wider use of adhesive joining will result in reduced vehicle weight, increased body stiffness, and improved crashworthiness. Adhesives are also a critical enabler for the joining of dissimilar materials.

  • Apply NDI methods to characterize weak bonds and quantify their strengths

To accomplish the above objectives, the various attributes that determine the bond strength must be identified. A nondestructive inspection method must developed to assure the strength of the adhesive. The success of this approach will be quantitative correlations of NDI to measured bond strengths for full strength bonds and weak bonds.
