Spar Cap Structural Integrity Inspection

Spar Cap Structural Inspection

The spar cap is the primary load-bearing structural element of a wind turbine blade. Our inspection employs encoded PAUT scanning and conventional pulse-echo UT to assess full length and cross-section of spar cap laminates, detecting delamination, fibre waviness, voids, and porosity with reliable characterisation for fitness-for-service assessment.
