A composite component for a vehicle has a core layer made from a theiinoplastic plastic foam and at least one cover layer which is connected to the core layer. The core layer has a higher density in one region than the density of the semi-finished core layer. The cover layer formed from a fiber-reinforced plastic is connected in the region of higher density to at least one joining element by friction welding.

A container is formed to include an interior region and a mouth opening into the interior region. The container includes a floor and a side wall coupled to the floor to define the interior region between the floor and the side wall

A rotor blade for a wind turbine may generally include a first blade component formed from a first fiber-reinforced composite including a first thermoplastic resin material and a second blade component configured to be coupled to the first blade component at a joint interface. The second blade component may be formed from a second fiber-reinforced composite including a second thermoplastic resin material. The second fiber-reinforced composite may include a low fiber region and a high fiber region, with the low fiber region having a fiber-weight fraction that is less than a fiber-weight fraction of the high fiber region. In addition, the first thermoplastic resin material of the first fiber-reinforced composite may be welded to the second thermoplastic resin material contained within the low fiber region of the second thermoplastic composite to form a welded joint at the joint interface between the first blade component and the second blade component.
