Abstract:
A method for production of a tubular body applying the following steps: Pressureless application of at least one first curable plastic layer made of reactive polyurethane materials with a core via a rotational molding process, Curing the at least one plastic layer, Winding at least one reinforcement layer onto the at least one first plastic layer, Pressureless application of at least one second curable plastic layer, wherein the reinforcement layer is embedded without holes between the two plastic layers, and Removal of the core after completion of the body. Because of this, the position of the reinforcement layer 7 can be individually established and it can be ensured that the reinforcement layer will not penetrate into the first plastic layer during winding after the curing of the first plastic layer.
