Fabricating a composite material comprising an assembly of synthetic reinforcement fibers and an impregnated thermoplastic polymer having a glass transition temperature of >= 80[deg] C, comprises impregnating the assembly by a precursor composition containing a prepolymer and a chain extender in a molten state, and polymerizing the prepolymer with the chain extender by polyaddition polymerization in a molten state. Fabricating a composite material comprising an assembly of synthetic reinforcement fibers and an impregnated thermoplastic polymer having a glass transition temperature of >= 80[deg] C, comprises impregnating the assembly by a precursor composition containing a prepolymer having a structure of formula (P1(X) n) and a chain extender having a structure of formula (Y1-A1-Y1) (Q) in a molten state, and polymerizing the prepolymer with the chain extender by polyaddition polymerization in a molten state. P1 : thermoplastic polymer including a molecular chain; X : reactive functions present at the end of the molecular chain; n : 1 or 2, preferably 2; and Y1 : reactive functions with X. Independent claims are included for: (1) a precursor composition comprising the prepolymer, the chain extender and the thermoplastic polymer having a glass transition temperature of >= 80[deg] C, preferably 110-170[deg] C; (2) an impregnated fibrous material, which is obtained from the impregnation of the assembly of synthetic reinforcement fibers with the precursor composition in the molten state; and (3) the composite material obtained by the process. |
