Abstract:
1. A multilayer laminate for stiffening a flat substrate comprising at least two heat-curable binder layers and two layers of fiber-containing flat textile materials, wherein a first binder layer faces the substrate to be stiffened, a second binder layer is remote from the substrate to be stiffened, a first layer of a fiber-containing flat textile material is arranged between the first binder layer and the second binder layer, a second layer of a fiber-containing flat textile material is arranged on the second binder layer remote from the substrate to be stiffened, the first binder layer facing the substrate to be stiffened being adhesively joined to the substrate to be stiffened and having the same elasticity modulus as, or a lower elasticity modulus than, the second binder layer when cured, wherein the surface areas of the second binder layer and the second layer of flat textile material are smaller than the surface areas of the first binder layer and the first layer of flat textile material.
