Abstract
A method for producing a plastic tank having one or more reinforcements. The method includes forming at least one part of the tank wall with a semi-finished panel made of plastic having at least one outer layer composed of a first thermoplastic, forming a reinforcement for the tank wall with at least one fibre-reinforced structural component comprising a matrix composed of a second thermoplastic that is weldable to the first thermoplastic. The fibre-reinforced structural component is then applied to a predefined region of the at least one outer layer of the semi-finished panel. The fibre-reinforced structural component is then fused with the outer layer of the semi-finished panel by applying heat to the semi-finished panel and the applied fibre-reinforced structural component. The fused fibre-reinforced structural component and semi-finished panel is then formed into a final shape. Optionally, the formed component is then connected to at least one other part of the tank wall to form the complete tank wall.
