摘要： A method for producing a multilayer pipe with an outer layer which forms a pipe outer contour, an inner layer which forms a pipe inner contour, and at least one intermediate layer by means of a centrifugal casting process. A mixture of resin and microfibers is supplied to a rotating die in order to form the inner layer, and a specified separation of the resin and the microfibers is produced by controlling the die rotational speed during a specified time such that the content of the microfibers in a boundary layer, which starts from the pipe inner contour, is lower than the content in a stability layer facing the intermediate layer. The invention likewise relates to a corresponding multilayer pipe.
