Effects of heating on the carrying capacity of composite fiberglass components

Conclusions 1.If there is reliable adhesion between the skins and the filling, one obtains the highest carrying capacity on loading at normal and elevated temperatures.2.The form of loading affects the carrying capacity at room temperature. For instance, if external hydrostatic pressure is accompanied by axial force, the carrying capacity is reduced by about 30% by comparison with the value for hydrostatic pressure alone. The effects of the detailed form of loading become somewhat less as the temperature is raised.3.The main factor affecting the carrying capacity of a multilayer conical shell at elevated temperatures is the loss of adhesion between layers.4.The carrying capacity of a conical shell falls considerably when both sides are heated to 70°C, or when one side is heated to 150°C (the fall is 50–70% relative to the same conditions at 20°C.
