Abstract

A method of forming a composite component comprising a layer which consists at least partly of polyethylene, a layer which consists at least partly of a polyurethane and/or an elastomer, at least one layer which consists at least partly of a plastic reinforced by fibers, or which consists at least partly of an adhesive, wherein the layer is disposed directly between the layer and the layer, wherein the layers have been joined in a first operation to form a laminate composite and the layer have been joined in a second operation onto the laminate composite comprising the layers.

First claim

The invention claimed is:

1. A method comprising:
producing a composite component, comprising:
forming a laminate composite comprising a first layer coupled to a second layer, the first layer including polyethylene, the second layer including an elastomer, wherein the elastomer is an ethylene-propylene rubber, ethylene-propylene-diene rubber, ethylene-acrylate rubber, fluorocarbon rubber, acrylate rubber, or acrylonitrile-butadiene rubber, wherein forming the laminate comprises vulcanizing the elastomer of the second layer; and
after forming the laminate composite, coupling a third layer with the laminate composite, the third layer including a plastic reinforced by fibers or an adhesive, wherein the plastic is a plastic resin system based on at least one of: epoxide, poly(meth)acrylate matrix, polymethyl (meth)acrylate matrix, or poly(meth)acrylamide matrix,
wherein the second layer is disposed directly between the first layer and the third layer, and
wherein coupling the third layer with the laminate composite comprises joining the third layer with the laminate composite and curing the third layer.

2. The method according to claim 1 , wherein coupling the third layer with the laminate composite comprises coupling the third layer directly with the second layer and curing the third layer.

3. The method according to claim 1 , wherein the third layer includes the plastic reinforced by fibers.

4. The method according to claim 1 , wherein the third layer includes the plastic reinforced by fibers, wherein the fibers are ultrahigh molecular weight polyethylene fibers.

5. The method according to claim 1 , wherein the third layer includes the plastic reinforced by fibers, wherein the plastic reinforced by fibers is a carbon fiber reinforced plastic or a glass fiber reinforced plastic.

6. The method according to claim 1 , wherein the polyethylene is one of: a high molecular weight polyethylene, an ultrahigh molecular weight polyethylene, or polytetrafluoroethylene.

7. The method as claimed in claim 1 , wherein the third layer includes the adhesive, wherein the adhesive is an epoxy resin adhesive.

8. The method as claimed in claim 1 , wherein the composite component is at least part of a wind turbine component.

9. The method as claimed in claim 8 , wherein the wind turbine component is a wind turbine rotor blade.

10. The method as claimed in claim 9 , further comprising securing the wind turbine rotor blade to a rotor of the wind turbine.
