| titleOfInvention | Fibrous material impregnated with thermoplastic polymer of optimum molecular mass and viscosity and method for the production thereof |
| abstract | The present invention concerns an impregnated fibrous material comprising at least one continuous-fibre fibrous material in the form of a roving or a plurality of parallel rovings and at least one thermoplastic polymer matrix, characterized in that said at least one thermoplastic polymer is an amorphous or semi-crystalline polymer having a glass transition temperature such that Tg ≥ 40°C, especially Tg ≥ 100°C, in particular ≥ 120°C, the fibre content of said impregnated fibrous material being from 45 to 65 % by volume, preferably from 50 to 60% by volume, especially from 54 to 60% by volume, the number-average molecular mass Mn of said thermoplastic polymer being from 11 000 to 25 000 g/mol, the melt viscosity of said thermoplastic polymer being from 80 to 1500 Pa.s, as measured by plate/plate rheology at 1 Hz and 2% deformation, at a temperature of Tg + 220°C. |
