Compensation of thermal stresses in glass-fiber-reinforced plastic articles by the layerwise winding method

The contact pressures which must be created during winding with layerwise hardening in order to compensate radial stresses on the contact surfaces of the layers are determined. The tensions realizing the necessary pressures are calculated. The relations obtained are checked experimentally.Institute of Polymer Mechanics, Academy of Sciences of the Latvian SSR, Riga.
