Abstract:
This report presents the results of tests to evaluate the effects of various types and durations of wet exposure on the tensile, compressive, and flexural properties of epoxy, polyester, phenolic, and silicone laminates reinforced with 181 glass fabric that had various types of fabric finish. The tests were made after normal conditioning and after various periods of wet exposure. Wet conditions used for (1)immersion in water at 73 degrees F, (2)exposure to an atmosphere at 100 degrees F and approximately 100 percent humidity, or (3)boiling in water.
