In this paper, the influence of temperature and humidity on the strength and modulus of graphite/epoxy is examined. The mechanical properties at several temperature/humidity conditions are compared to baseline room-temperature dry conditions. A technique for using a high-temperature/high-humidity soak prior to test to accelerate attaining a wet condition is discussed. Stresses and strains at failure are presented and reduced to a B-basis. Data for unidirectional laminates are given for tension, compression, and shear both parallel and transverse to the fiber direction. Three multidirectional laminates typical of aircraft construction are also examined.
