An aircraft rotor blade (1) having a root portion (2) having a through seat (3) and designed for connection to the rotor; and a main portion (4) extending from the root portion (2). The blade (1) is produced by polymerizing an assembly having a main structure (5) of composite material, and a composite material covering (6) defining the outer surface (7) of the blade (1). At the root portion (2), the main structure (5) has a contoured block (8); and a lamina member (16) extending about at least part of the block (8), and having a first part (17) adhering to a first peripheral portion (12) of the block (8), and a second part (18) spaced apart from and facing a second peripheral portion (13) of the block (8) to form the seat (3); the lamina member (16) having a pre-preg of continuous unidirectional fibres. |
