Compound plastic pipe comprises an intermediate connector layer between the inner and outer pipe layers which consists of glass fibers with woven-in chain and/or weft elements made of a thermoplastic material

摘要

The compound pipe with a thermoplastic inner layer, a glass fiber reinforced outer layer, and a glass fiber intermediate connector layer (3) is characterized by the fact that the connector consisting of glass fibers (4) contains woven-in chain and/or weft elements (4) made of a thermoplastic material which is weldable to the thermoplastic material of the inner layer.
