METHOD TO PRODUCE A RECYCLED MATERIAL WITH PREFERRED ORIENTATION OF FIBRES FROM THE MULTILAYER UNCURED PREPREG SCRAP GENERATED IN THE MANUFACTURING OF AERONAUTICAL PARTS WITH PREPREG MATERIAL

Abstract: a method to produce a recycled material with preferred orientation of fibers from the multilayer uncured prepreg scrap generated in the manufacturing of aeronautical parts with prepreg material, comprising: collection of the unused scrap from the manufacturing of aeronautical parts; removal of materials other than the prepreg material of the scrap; transfer of the scrap free of additional materials to a cutting station; cutting the scrap in strips parallel to the predominant orientation of the fibers in the cutting station; transfer of the strips to a station of several successive stages of rollers, and the strips pass through each successive stage of rollers in the station, such that the thickness of the strips is progressively reduced after passing through each successive stage of rollers in the station.
