The request for high quality fiber reinforced products is increasing because of high quality demands from the aerospace industry. Because of new resin qualities for faster curing processes the machinery builders are requested to react with the further development of coating and impregnation technologies for carbon fibers handling these new resins. Higher viscos resins applied at lower temperatures applied with highest precision and stability are the focus for developments at side of machinery builders.
Machinery supplier can support these requests with high quality processes to reach at least comparable processes for the production of composite materials. Each process step starts from the resin film production up to the fiber impregnation process. There are numerous criteria in the process which have to be well adjusted and monitored for a reproducible process.
With the presentation we will emphasize our experience in the different process steps for the prepreg production and highlight how the machine can influence the prepreg quality as well as which new coating technologies were developed to follow the future market demands.
