| titleOfInvention | Method for producing fibrous material preimpregnated with thermoplastic polymer in powder form |
| abstract | The present invention is a method of producing a pre-impregnated fiber material comprising continuous fiber fibrous material and at least one thermoplastic polymer matrix, the pre-impregnated fiber material comprising a single unidirectional ribbon or a plurality of unidirectional parallel fibers. Being made of ribbon and characterized in that the method comprises a step of impregnating the fibrous material in the form of a roving with the thermoplastic polymer in powder form or several parallel rovings, especially in a core. The impregnating step is performed with the at least one thermoplastic polymer and the fibrous material, and the ratio of the D90 / D10 of the at least one thermoplastic polymer and the fibrous material by volume of the thermoplastic polymer particles is: Thermoplastic polymer particles in the range from 1.5 to 50, in particular from 2 to 10, based on the average diameter of the unit fibers of the fibrous material. The ratio of the average volume diameter (D50) of the carbon fiber fiber material in the aqueous suspension with the thermoplastic polymer containing the ratio of D50 / unit fiber average diameter of 3 to 8 is optional. The manufacturing method is in a range of 3 to 40, excluding an electrostatic process in charging. |
