Propeller blade or airfoil with root wound with composite material
The invention relates to a propeller blade or airfoil (10) for a turboprop engine, made of a composite material and comprising a matrix-densified fibrous reinforcement, the propeller blade or airfoil comprising, in a longitudinal direction (DL), a root (12) and an aerodynamic profile (11). The fibrous reinforcement comprises a fibrous preform (200) in the form of a three-dimensional woven body having a root preform portion (121) in the root (12) and an aerodynamic profile portion (211) in the aerodynamic profile (11), the root preform portion (212) and the aerodynamic profile preform portion (211) being joined to each other by three-dimensional weaving. The root preform portion (212) includes two woven skin layers (2121, 2122) wound about the insert (130).
本发明涉及一种用于涡轮螺旋桨发动机的螺旋桨叶片或翼型件(10)，其由复合材料制成并包括基质致密化的纤维增强体，该螺旋桨叶片或翼型件沿纵向方向(DL)包括根部(12)和空气动力学轮廓(11)。该纤维增强体包括呈三维编织体的纤维预成型件(200)，其具有位于根部(12)中的根部预成型件部分(121)和位于空气动力学轮廓(11)中的空气动力学轮廓部分(211)，根部预成型件部分(212)和空气动力学轮廓预成型件部分(211)通过三维编织彼此连结。根部预成型件部分(212)包括绕插入件(130)缠绕的两个编织表层(2121，2122)。
