Abstract
A plastic hollow body, in particular plastic pipe, the wall of which is constructed from cylindrical layers bonded to one another, wherein at least one layer is a layer made of a thermosetting material produced in the centrifugal process and the plastic hollow body includes multiple layers of thermosetting material and multiple layers of thermoplastic material.
Claims24
Plastic hollow body having a wall which is constructed from cylindrical layers that are each bonded to one another by a frictional connection, said frictional connection formed by a coupling agent disposed between each of said cylindrical layers, said cylindrical layers comprised of multiple layers of a thermosetting material and multiple layers of a thermoplastic material,
- wherein one or more of said layers of said they material are disposed between layers of said thermoplastic material,
- wherein the number of layers of said thermosetting material that are disposed between layers of said thermoplastic material varies throughout said plastic hollow body, and
- wherein at least one of said layers of said thermosetting material is produced in a centrifugal process.
