Bonding of Elevated Temperature Strain Gages to Humid Aged Graphite Tensile Specimens through the Use of Anaerobic Adhesives.

摘要

In order to study the effects of moisture on graphite composites at elevated temperatures, new techniques of adhesively bonding strain gages to test specimens had to be developed. All of the current elevated temperature strain gage adhesives require heat and pressure with varying lengths of time at temperature in order to cure. A room temperature curing, elevated temperature adhesive would be very desirable in order not to negate the moisture effects (dry-out the specimens) or further cure the specimens. The use of anaerobic adhesives was found to be the solution to this problem. New techniques were developed for gage application and other applications were found to utilize this adhesive's unique characteristics. (Author)
