Beschreibung
Zusammenfassung:	A method of manufacturing a component made of composite material whereby the said component is obtained from a preform containing local reinforcers and a first resin of low viscosity. The method includes: creation of the said preform comprising a first fibrous material and the said local reinforcers being in the form of reinforcers formed of a second fibrous material having fibres of mechanical strength greater than that of the fibres of the first fibrous material, so that they exhibit an elastic modulus or breaking stress at least 30% higher than that of the fibres of the said first fibrous material, the said second fibrous material being pre-impregnated with a thermoplastic, acrylic or polyamide polymer second resin having a glass transition temperature (Tg) above 80° C., the amount of polymer second resin being comprised between 25% and 60% by volume with respect to the total volume of the said second fibrous material.
