PRODUCTION METHOD AND PRODUCTION DEVICE FOR FAN BLADES

摘要

A raw material plate (7) comprising a plurality of main fibers (71) oriented in parallel, a plurality of auxiliary fibers (72) oriented in parallel and intersecting the main fibers (71), and a resin that integrates these main fibers (71) and auxiliary fibers (72) is sandwiched by a frame-shaped blank holder (8), in a state in which the resin is heated to a temperature at which same becomes soft. The raw material plate (7) sandwiched by the blank holder (8) is pressed on to a fan blade mold (6b) such that the direction of the main fibers (71) matches the longitudinal direction (Y) of the fan blade mold (6b), thereby applying a suitable tension to the raw material plate (7) along the main fiber (71) direction, and suppressing creases.
