Sets of coated and uncoated glass-reinforced epoxy and polyester laminate panels,have been exposed to the atmosphere at Port Hueneme and China Lake, California and at Kwajalein, Marshall Islands. A fourth set has been manintained at NCEL as a control. Results of physical tests of panels exposed at the three field locations for periods of 36 to 44 months and results of the same tests on control panels are reported. Comparisons of the mean and standard deviations of the tesnile strength, compressive strength, flexural strength and flexural modulus of elasticity of the panels are presented. Weather data from the three exposure sites are also presented for the last exposure period. To date, polyester- glass laminate panels have higher ratings than epoxy-glass laminate panels, and panels gel-coated. Also panels exposed at China Lake rated higher than those exposed at Kwajalein or Port Heneme. Author-PL
