Abstract

Tensile tests of glass-cloth plastic laminates showed that modulus of elasticity and proportional-limit stress may be changed considerably after the first application of stress. A small number of preloads, in either tension or compression, have no appreciable effect on the strength of the laminate. The application of many repeated or reversed stresses, however, may result in a fatigue strength that is much lower than the static strength of the material.
