Wind turbine rotor blade components formed from pultruded hybrid-resin fiber-reinforced composites

摘要

A rotor blade component for a wind turbine rotor blade may generally include an assembly of pre-formed pultruded products. Each pultruded product may include an interior pultruded portion formed from a first fiber-reinforced composite including a first plurality of fibers surrounded by a thermoset resin material and an exterior pultruded portion encapsulating the interior pultruded portion. The exterior pultruded portion may be formed from a second fiber-reinforced composite including a second plurality of fibers surrounded by a thermoplastic resin material.
