  • Method for recycling scraps of prepreg materials
    Patent number: 8298359
    Abstract: A method for manufacturing a recycled prepreg material in strip form, is composed of fiber sections embedded in a resin matrix. A charge of flat scraps from a prepreg starting material is supplied, recording the overall area of the scraps. Then the scraps are fragmented by cutting so as to obtain cut fragments of predetermined size. A strip of backing material and a strip of protective material are supplied. The cut fragments are then distributed in a random manner on the strip of backing material, the feeding speed of the strip of backing material being adjusted depending on the recorded area of the input scraps, so that the cut fragments form a substantially homogeneous layer. The strip of protective material is then arranged over the cut fragments distributed on the strip of backing material, and the whole assembly is then compacted so as to form a strip of recycled prepreg material.
