A composite laminate is made by providing at least a first composite ply and a second composite ply, each having longitudinally oriented fibers in a thermoplastic matrix. The second composite ply is disposed on, and in transverse relation to, the first composite ply. Preferably, the second ply is disposed at 90 relative to the first ply. An article can be manufactured by providing a core material and applying a reinforcing material to a portion of the core material. The reinforcing material is a reinforcing composite ply or a composite laminate as described herein. Optionally, the core material is a prepreg that may be a composite laminate.

The present disclosure is directed to a method for bonding composite blade components of a rotor blade of a wind turbine. The method includes providing a first blade component being constructed of a first composite material. The method also includes providing a second blade component being constructed of a second composite material. Further, the method includes arranging the first and second blade components together at an interface. Another step includes placing one or more layers of a wetted composite material between the first and second blade components at the interface. The method also includes allowing the one or more layers of the wetted composite material at the interface to cure.

A device is provided for producing a bonded joint between fiber-reinforced thermoplastic parts to be joined, in which fiber-containing plastic material is mixed into the joining zone while friction stir welding the parts to be joined in the form of a butt joint.

A process for fixing an article to a substrate with a mounting set including two receptacles storing an aerobic adhesive and a hydrophilic substance, respectively. The aerobic adhesive and the hydrophilic substance are removed from the two receptacles and then mixed together to prepare the fastening. A layer of the fastening composition is applied to the article. The article is fixed to the substrate by pressing the layer of the fastening composition against the substrate. The aerobic adhesive in the layer hardens because of the moisture contained in the hydrophilic substance.
