Composite Article For Conveying And/Or Storage Of Liquid and Gaseous Media And A Process For Producing The Same

A process for manufacturing a composite article for conveying and/or storage liquid and gaseous media comprising at least an internal sealing layer and an external load-bearing layer, comprising the steps of:

• applying a sevilene layer onto a polyolefin parison tube forming said internal sealing layer;
• placing a fibrous structure over said sevilene layer;
• subsequently heating said fibrous structure up to a temperature providing for gluing the polyolefin parison and the fibrous structure;
• winding a composite polymer material consisting of fibers impregnated with synthetic resins which are suitable binding agents both for fibers of said composite polymer material and fibers of said fibrous structure
• followed by polymerizing said resins to form cured composite load-bearing layer.
