ABSTRACT:
A process for patching a crack or other defect in a thick-walled steel component, such as the wall of a pressure vessel, is provided. Stacked sheets of pre-impregnated carbon fiber-reinforced epoxy are bonded together and cured by interposed layers of a second resin. A structural adhesive is used to bond the stack to the steel to form the patch.
