Minimization of Thermal Stresses in Filament Wound Flextensional Shells

Abstract

Thermally induced stresses, resulting from curing, in a composite part can result in transverse tensile cracks or premature failure under loading. The magnitude of the predicted thermal stresses arising from cool down can be quite large with respect to the transverse strength properties. To minimize these stresses in large thick filament wound fiberglass/epoxy composite parts a curing conditions should be at a slow heat-up and a maximum temperature of 275 deg F.
