METHOD OF MANUFACTURING CASE AND THE CASE

摘要

PROBLEM TO BE SOLVED: To sufficiently enhance strength and rigidity of a fan case 1 by suppressing wrinkles and meandering of fiber leading to deterioration of strength of a composite material even when manufacturing the fan case 1 having an outside diameter largely varied along an axial direction. SOLUTION: A texture winding process for winding a texture 25 on a molding surface S side of a mandrel 7 and a roving winding process for spirally winding a roving 35 on the molding surface S side of the mandrel 7 in the state of maintaining a tilt angleβof -10 to +10 degrees with respect to a peripheral direction of the mandrel 7 are alternately repeated for a plurality of times.
