摘要： A process for producing a thermoplastic composite pipe, where the process includes: a) providing a tubular liner having a wall containing a thermoplastic polymer A in the region of the outer surface; b) providing a tape containing reinforcing fibres in a matrix containing a thermoplastic polymer B, where polymer A and polymer B are different; c) applying a film or a composite which is produced in d) and is composed of a film and a tape provided in step b) to the tubular liner, with melting of the outer surface of the liner and of the contact surface of the film either beforehand, simultaneously or thereafter, d) applying the tape provided in b) to the outer surface of the film, with melting of the outer surface of the film applied and of the contact surface of the tape either beforehand, simultaneously or thereafter, where the surface of the film which is brought into contact with the liner contains a moulding compound containing polymer A to an extent of at least 30% by weight, and the opposite surface of the film contains a moulding compound containing polymer B to an extent of at least 30% by weight.

摘要： A process for producing a thermoplastic composite pipe is provided. The thermoplastic composite pipe thus produced contains a liner, two or more composite layers composed of tape laminas, and a single- or multilayer intermediate lamina arranged between different composite layers. Composite formation between identical polymers in the process achieves improved adhesion. The thermoplastic composite pipe is especially suitable for offshore applications in oil or gas production.

摘要： A process for producing a thermoplastic composite pipe, where the process includes:



a) providing a tubular liner having a wall containing a thermoplastic polymer A in the region of the outer surface;
b) providing a tape containing reinforcing fibres in a matrix containing a thermoplastic polymer B, where polymer A and polymer B are different;
c) applying a film or a composite which is produced in d) and is composed of a film and a tape provided in step b) to the tubular liner, with melting of the outer surface of the liner and of the contact surface of the film either beforehand, simultaneously or thereafter,
d) applying the tape provided in b) to the outer surface of the film, with melting of the outer surface of the film applied and of the contact surface of the tape either beforehand, simultaneously or thereafter,

where the surface of the film which is brought into contact with the liner contains a moulding compound containing polymer A to an extent of at least 30% by weight, and the opposite surface of the film contains a moulding compound containing polymer B to an extent of at least 30% by weight.
