Multi-layer body structure for the reinforcement of a panel and a methodof reinforcing a panel

Abstract From the Canadian patent

The multi-layer body member consists of a support member e.g. a glass fiber tissue impregnated with a thermosettting resin which is covered by a layer of thermosetting adhesive resin. In order to protect the sticky surface of the adhesive resin a, protection foil made of a material shrinking under the influence of heat is provided. The foil comprises slits which open to apertures after a preliminary heat treatment such that an essential portion of the sticky resin surface is freely exposed. Thus, the need to remove the protection foil prior to applying the multi-layer body member to the surface to be reinforced is removed.
