PRODUCTION METHOD AND PRODUCTION DEVICE FOR FAN BLADES

摘要

A heated blank sheet (7) is held by a frame-like shaped blank holder device (8), the blank sheet (7) including a plurality of main fibers (71) arranged in parallel with each other, a plurality of auxiliary fibers (72) arranged in parallel with each other so as to intersect with the main fibers, and a resin that consolidates the main fibers (71) and the auxiliary fibers (72), and the blank sheet (7) held by the blank holder device (8) is pressed against a fan blade mold (6b) with the direction of the main fibers (71) aligned with a longitudinal direction (Y) of the fan blade mold (6b) to apply an appropriate tension along the direction of the main fibers (71) to the blank sheet (7), thereby preventing occurrence of wrinkling.
