Sheet of strengthening for the strengthening of the panel and process to support a panel formed of metal, plastic or sheet molding compound

摘要

A reinforcing sheet adaptable to the reinforcement of a panel formed of metal, plastic or sheet molding compound, which reinforcing sheet contains a moisture impermeable barrier embedded in a thermosetting adhesive layer and a reinforcement adhered to the surface of the adhesive layer opposite the surface to be applied to the panel to be reinforced. The reinforcing sheet with improved resistance to the adverse effects of moisture is advantageously used to reinforce cold rolled steel, such as an automobile panel.
