Title: FAN BLADE
Abstract:
Provided is a fan blade which is made of a composite material and which will not suffer damage even if a large foreign object collides with the fan blade. A fan blade (20) is provided with a blade body (21) composed of a composite material of thermoplastic resin or thermosetting resin and reinforcement fiber, a sheath (22) made of metal for at least partially covering a leading edge section (LE) of the blade body, and a guard (23) made of metal for at least partially covering a trailing edge section (TE) of the blade body. A trailing end section of the sheath and leading end section of the guard overlap in the thickness direction of the blade body on each plane of a positive pressure surface (SP) and a negative pressure surface (SS) of the blade body. In the overlapped sections (OL1, OL2), the leading end section of the guard is interposed between the trailing end section of the sheath and the blade body.
