| 摘要 |
The present invention relates to a manufacturing method of a blade in which a mold is constituted to be separated into two parts, and which performs winding and demolding of high-intensity fiber to a root unit by removing a mold part closer to the root unit of the blade. Accordingly, being different from conventional demolding methods, blade damage caused by lifting load can be eliminated by dispersing the lifting load applied to a specific part, and high-strength wound fiber can enhance an insignificant amount of strength with respect to a contact area of upper and lower shell bonding parts of the root unit. |
