Abstract
The testing of sealant samples has been restricted to devices that either focus on fatiguing multiple samples or quantifying the mechanical properties of a single sample. This manuscript describes a device that combines these two instrumental designs: the ability to both fatigue and characterize multiple sealant samples at the same time. This device employs precise movement capability combined with a stiff loading frame and accurate force measurement for the characterization of five ASTM C719 sealant samples. The performance of this device is demonstrated by monitoring the changes in mechanical properties of silicone sealant during the first 90 h of cure. A complete description of the apparatus, results from the study of curing and analysis is included.
