MULTI-LAYER REINFORCING LAMINATE

摘要

The invention relates to multi-layer laminates consisting of at least two thermosetting binding-agent layers and two layers consisting of textiles, said laminates being suitable for reinforcing planar substrates. The inventive multi-layer system contains a binding-agent layer facing the substrate to be reinforced (11), followed by a fibrous-textile layer (13), covered by a second binding-agent layer (14), which is covered in turn by a second fibrous-textile layer (15). Once cured, the binding-agent layer facing the reinforcing substrate forms an adhesive bond with the substrate to be reinforced and has either an identical or lower elasticity modulus than the second binding-agent layer (14) facing away from the substrate. Multi-layer laminates of this type are suitable for reinforcing thin-walled substrates with no read through effect, in particular automobile construction parts with large surface areas, such as doors, roof parts, engine compartment covers, boot lids or similar.
