Mold Assembly For Infusing A Spar Cap And Related Methods
Patent No. EP4238751 (titled "Mold Assembly For Infusing A Spar Cap And Related Methods") was filed by LM Wind Power on Mar 2, 2022. The application was issued on Dec 18, 2024.
Patent Summary
A method for manufacturing a wind turbine blade spar cap comprises laying a stack of pultruded plates on a mold between a first and a second sidewall, infusing the stack with resin, and unmolding the infused stack. The process is characterized by adjusting at least one of the sidewalls along a transverse direction relative to the pultruded plate stack, occurring at least after the laying step or prior to the unmolding step. This adjustment addresses alignment difficulties and imperfections associated with pultruded plate integration in composite manufacturing, reducing manual labor and increasing production throughput compared to conventional mold assemblies. The corresponding mold assembly comprises a mold surface with longitudinal and transverse directions and at least two sidewalls, where at least one is transversely adjustable.
