INDUCTION CONSOLIDATION FOR WIND TURBINE BLADE FABRICATION

Title:

INDUCTION CONSOLIDATION FOR WIND TURBINE BLADE FABRICATION

Document Type and Number:

Japanese Patent JP2017110519

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide an improved thermoplastic composite tubular structure in fabricating wind turbine blades, and an improved method for fabricating these blades.SOLUTION: A method of fabricating a thermoplastic composite tubular structure for use as a wind turbine blade is presented using a combination of induction heating with smart susceptors 24, 26 to consolidate a wrapped mandrel 3. The method includes overbraiding the mandrel 3 with a continuous fiber thermoplastic composite material to form an overbraided mandrel 8 that is then installed in a ceramic induction oven where the mandrel 3 is pressurized internally to consolidate the thermoplastic overbraid during heating.SELECTED DRAWING: Figure 5
