Pultrusion Process Control for Wind Spar Caps: Cure Kinetics, Pulling Force, and IEC 61400-5 Quality
Pultruded carbon fiber plates have displaced prepreg layup as the dominant process for wind turbine spar caps, and the reason is economic: a pultrusion line converts carbon fiber tow into finished plate at speeds of 0.3-1.5 meters per minute with a fraction of the labor of hand layup, w
