Title:
Z-PIN REINFORCED COMPOSITE WIND TURBINE BLADE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/169940
Kind Code:
A1
Abstract:
A Z-pin reinforced composite wind turbine blade and a manufacturing method therefor, the Z-pin reinforced composite wind turbine blade comprises: shells, that are composed of an upper shell and a lower shell. A connection layer is provided at a joint between the upper shell and the lower shell, an upper portion of the connection layer fits an inner side of the upper shell, a lower portion of the connection layer fits an inner side of the lower shell, and a Z-pin for improving the connection strength is embedded between the upper portion of the connection layer and the upper shell, and between the lower portion of the connection layer and the lower shell. The Z-pin reinforced composite wind turbine blade further comprises: a main beam, the main beam and the inner side of the upper shell being fitted to form an upper bonding surface, the main beam and the inner side of the lower shell being fitted to form a lower bonding surface. A Z-pin for improving the connection strength is embedded at a joint of the upper bonding surface and a joint of the lower bonding surface, and two sides of the main beam are also filled with filling foam within the shells.
