Abstract : Sets of coated and uncoated glass-reinforced epoxy and ther-mosetting polyester laminate panels were weathered at Port Hueneme and China Lake, California, and at Kwajalein, Marshall Islands. A control set was maintained at CEL. Physical tests were performed on the panels over periods up to five years. Comparisons of the mean and standard deviations of the tensile strength, compressive strength, flexural strength, and flexural modulus of elasticity are presented and their surface condition reported. Based on an analysis of the data obtained from the physical tests the general-purpose polyester laminate performed better than the general- purpose epoxy laminate; gel coats were superior to spray-on coatings; and coated panels were superior to uncoated panels.
