Method for producing a flexible composite pipe, and thermoplastic composite pipe

Abstract

A method for producing a flexible thermoplastic composite pipe, wherein the method comprises the following steps: applying a first ply of a reinforcing layer onto a plastics pipe; consolidating the first ply of the reinforcing layer with the plastics pipe, wherein at least the first ply of the reinforcing layer is brought to a first temperature which leads to at least partial melting of the first ply of the reinforcing layer, such that the first ply of the reinforcing layer and the plastics pipe are rigidly interconnected, in particular in a fused manner; applying a second ply of the reinforcing layer onto the first ply of the reinforcing layer; consolidating the second ply of the reinforcing layer with at least the first ply of the reinforcing layer, wherein at least the second ply of the reinforcing layer is brought to a second temperature which leads to at least partial melting of the second ply of the reinforcing layer, such that the second ply of the reinforcing layer and the first ply of the reinforcing layer are rigidly interconnected, in particular in a fused manner; applying at least a third ply of the reinforcing layer onto the second ply of the reinforcing layer; consolidating the at least one third ply of the reinforcing layer with at least the second ply of the reinforcing layer, wherein at least the third ply of the reinforcing layer is brought to a third temperature which leads to at least partial melting of the third ply of the reinforcing layer, such that the third ply of the reinforcing layer and the second ply of the reinforcing layer are rigidly interconnected, in particular in a fused manner, and thermoplastic composite pipe and the use of a thermoplastic composite pipe.
