The elastic material constants of filament-wound, glass-reinforced-plastic cylinders fabricated from E-HTSE787 and S-HTSE787 preimpregnated rovings were experimentally determined for the case of plane stress. Cylinders with a 3.2-in. diameter were stressed under unidirectional loadings and the strains were measured to determine the elastic moduli and Poissons ratios. The engineering elastic constants were then used to predict the measured strains of the 3.2-in.-diameter cylinders and also 6-in.-diameter cylinders subjected to biaxial hydrostatic pressure loading. The measured strains compared favorably with prediction. Author
