Abstract
The multi-layer body member consists of a support member, e.g. a glass fiber tissue impregnated with a thermosetting 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 meterial 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.
