Abstract

The braiding pultrusion process is an innovative process chain to produce fibre reinforced thermoplastic profiles with a load adaptive fibre design. At first hybrid yarns are braided on a continuously fed mandrel. After the braiding process the hybrid textiles are heated, shaped and cooled down in a hot press unit. A pultrusion process for thermoplastic composites was designed and set up. The paper describes the project results and gives an outlook on future developments. A method is described how inserts can be integrated during the braiding process. The paper also describes a way to evaluate the economic factors of the process line. There are investigations to heat up the carbonfibre profiles with electrical resistance heating. First experimental results are listed. The results show that an economical production is possible with the new technology. The presented concept for the insert integration was approved. During pull out tests the inserts could not been pulled out of the profiles. The maximum force was 6 kN.
