The invention relates to a method (100) for manufacturing a blade, the method comprising: a preparation step (102) of arranging a spar preform in a first mold, the spar preform comprising a core and a root; a first injection step (104) of injecting a first thermosetting resin into the spar preform; performing a partial polymerization step (106) of the first resin in the spar preform until the first thermosetting resin partially vitrifies; a positioning step (108) of positioning a body preform around the core of the spar preform; injecting a second resin into the preform of the blade body; and a step of completely polymerizing the first resin and the second resin.
本发明涉及一种用于制造叶片的方法(100),该方法包括:将翼梁预制件布置在第一模具中的准备步骤(102),翼梁预制件包括芯部和根部;将第一热固性树脂注入到所述翼梁预制件中的第一注入步骤(104);进行所述翼梁预制件中的第一树脂的部分聚合步骤(106),直到第一热固性树脂部分玻璃化;围绕所述翼梁预制件的芯部定位主体预制件定位步骤(108);将第二树脂注入到该叶片主体的预制件中;以及完全聚合第一树脂和所述第二树脂的步骤。
