The invention concerns a method which consists in placing a fibrous structure for forming a reinforcement of the part to be produced in a mould (22) having a wall at least formed by a flexible membrane, then injecting in the mould a resin composition having a weight ratio of volatile materials less than 25 % and a temperature of a value such that its viscosity ranges between 0.1 Pas and 0.3 Pas. The polymerization of the resin is carried out in the mould placed in a chamber (20) while gradually raising the temperature and comprises at least one final polymerization phase under pressure to obtain a part made of composite material exhibiting a residual volume porosity less than 11 %. |
