    Abstract: The present invention relates to a membrane comprising a bulkhead layer, wherein more than 50% by weight of the bulkhead layer is composed of PVC, and a barrier layer. The barrier layer can, on the one hand, be a barrier layer S1, wherein the barrier layer S1 has a polyvinyl alcohol layer comprising more than 50% by weight of copolymer PA, which is connected to the bulkhead layer by a polyurethane layer, wherein more than 10% by weight of the polyurethane layer is composed of polyurethane PUR. The barrier layer can, on the other hand, be a barrier layer S2, wherein the barrier layer S2 has a composition comprising 5-50% by weight of polyurethane PUR and 50-95% by weight of copolymer PA. The membranes according to the invention have significantly lower plasticizer migration compared to the membranes of the prior art and are distinguished by improved resistance to aging, particularly as regards the adherence of the barrier layer on the bulkhead layer, and imperviousness to damp.

    Abstract: Components with improved erosion resistance are disclosed. A surface of the component or a substrate of the component is modified by coating the substrate with an elastomer layer. The elastomer layer is then modified by embedding hard particles onto an outer side of the elastomer layer. The hard particles exhibit higher fractured toughness providing enhanced erosion protection. The elastic properties of the elastomer experience little reduction because the surface embedded particles are located only at the outer side or outer surface of the elastomer layer. Therefore, the bond between the inner side of the elastomer layer and the substrate or component surface is not interfered with and the potential for electro-chemical corrosion and poor adhesion are not increased by the presence of the hard particles as the hard particles are located away from the inner face between the elastomer layer and the substrate.
