Abstract:

A REFINED BUTT-JOINT CHAIN METHOD WAS CAPABLE OF MEASURING AN AVERAGE BOND STRENGTH OF ABOUT 1000 PSI, WITH A STANDARD DEVIATION OF ONLY ABOUT 300 PSI FOR 12 SPECIMENS OF A CHEMICALLY CLEANED GLASS-EPON 828 CL SYSTEM. THE REPRODUCIBILITY WAS MUCH IMPROVED IN COMPARISON TO PREVIOUS SPECIMEN DESIGNS. EVALUATION OF THE PRESENT SPECIMEN DESIGN ON AN A-1100 TREATED CHEMICALLY CLEANED GLASS SURFACE WILL BE CONTINUED. FURTHER WORK WILL ALSO BE DIRECTED TOWARD REFINING THE IMPROVED METHOD OF MEASURING BOND STRENGTH. A REVIEW OF SPECIMEN DESIGNS AND PROBLEMS LEADING TO THE PRESENT DESIGN IS PRESENTED IN THIS REPORT.
