AI Technical Summary

Benefits of technology

The technical effect of this patented technology relates to an improved strengthening material used on wind turbine generators (WTGs) during construction or maintenance procedures. This improves their overall durability while also making them lighterweight without sacrificing its performance.

Problems solved by technology

This patented describes how increasingly heavy or stiff blades used in wind turbines require stronger components like frames due to their ability to bear large loads without adding extra weights compared to thin ones. To address this problem, proposes making certain parts heavier by reducing the amount needed but also considering factors like durability against corrosion caused by rainwater impacts during operation. Additionally, introduces new designs aiming at achieving greater flexibility while maintaining structural integrity under harsh conditions.

Embodiment Construction

[0035]The reinforcing sheet for wind power generator blades of the present invention includes a resin layer and a restricting layer laminated on the resin layer.

[0036]The resin layer is formed by molding a resin composition in a sheet form.

[0037]The resin composition is not particularly limited as long as it contains at least a resin component. The resin composition optionally contains a curing agent, a crosslinking agent, a foaming agent, and a tackifier depending upon the kind of the resin component.

[0038]The resin component is not particularly limited, and examples thereof include thermosetting resin and thermoplastic resin. Preferably, a thermosetting resin is used.

[0039]The thermosetting resin is not particularly limited and examples thereof include epoxy resin, acrylic resin, and synthetic rubber.

[0040]The epoxy resin is not particularly limited, and examples thereof include aromatic epoxy resin, aliphatic and alicyclic epoxy resin, and ring containing nitrogen epoxy resin.
