Abstract
A method including the preparation of a spar preform arranged in a first mould, the spar preform including a core and a root; a first injection step of a first thermosetting resin in the spar preform; partial polymerization of the first resin in the spar preform until partial vitrification of the first thermosetting resin; positioning a body preform around the core of the spar preform; injection of a second resin into the blade body preform; and complete polymerization of the first and second resin.
Claims11
A method for manufacturing a blade, in-particular a composite blade, comprising at least:
- a preparation step, at which a preform of a spar comprising at least one core, is arranged in a first mould;
- a first injection step, at which a first resin is injected into the preform of the spar;
- a partial polymerization step, at which polymerization of the first resin in the preform of the spar is conducted until partial vitrification of the first resin;
- a positioning step, at which a preform of a body of the blade is positioned around the core of the preform of the spar;
- a second injection step at which a second resin is injected into the preform of the body of the blade;
- and
- a complete polymerization step at which final polymerization of the first resin and second resin is performed.
