Composite Repair Research Gathers Momentum

MADRID—Bolt-on metal repairs to primary composite structures could become a thing of the past, as work to improve the acceptance and standardization of bonded repairs progresses, experienced repair providers suggest.

Bolted repairs can be detrimental, cutting the composite structure’s residual strength by up to 50% and adding extra weight. But regulators do not yet accept bonding.

“We have made the first step … in increasing the reliability and acceptance of bonding as a repair method,” Christian Sauer, Lufthansa Technik’s(LHT) engineering manager for airframe-related component services, announced at MRO Europe 2014.
