Blade made of composite material for turbine engine stator comprising hollow core made of non-porous plastic

A bucket (46) for a turbine engine, the bucket comprising: a body (54) in the shape of an airfoil, the body being formed from an outer shell (56) made from a composite material formed from a three-dimensional fabric of reinforcing fibers consolidated by a hardened resin, the outer shell forming a pressure surface of the bucket connected to each other and a suction surface of the bucket, and a core (58), the core (58) being formed from a three-dimensional fabric of reinforcing fibers consolidated by a hardened resin, and a core (60) that forms a leading edge (64) of the vane on one side and a trailing edge (66) of the vane on the opposite side, the core comprising a core body (59) surrounded by an outer shell (56). The core (58) is made of a non-porous plastic material, and the core body (59) is airfoil-shaped and defines at least one closed cavity (68; 68A-68D) of the method. 一种用于涡轮发动机的轮叶(46)，该轮叶包括：呈翼型形状的主体(54)和芯部(58)，该主体由复合材料制成的外壳(56)形成，该复合材料由通过硬化树脂固结的增强纤维的三维织物形成，该外壳形成轮叶的彼此连接的压力表面和轮叶的吸力表面，同时在一侧形成轮叶的前缘(64)并且在
