Composite Structures

Lufthansa Technik's composite structures capability spans the full repair spectrum for the bonded and carbon fibre reinforced plastic (CFRP) components that define modern aircraft construction — from secondary panel repairs on the ramp to primary structure restoration requiring the highest cure parameters. The Hamburg workshop anchors the operation, housing an autoclave measuring five metres in diameter and six metres in length, capable of processing components at up to 16 bar and 250 °C. This allows Lufthansa Technik to cure even the largest CFRP parts — including empennage panels and nacelle barrels — that exceed the capacity of most commercial repair stations.

Capability is OEM-licensed across all repair levels, and Lufthansa Technik holds an EASA Part 21 Subpart J Design Organisation Approval, enabling it to develop and approve novel repair schemes for structures and systems on effectively all commercial aircraft types rather than being limited to pre-documented OEM procedures. This is a significant differentiator for out-of-routine damage where no standard repair exists.

The mobile dimension is delivered through the AST Nacelles and Composites team and the proprietary CAIRE mobile repair system, which brings controlled composite curing to the aircraft stand or remote station without ferry flight. A spare parts pool of approximately 1,100 major composite assets supports rapid component exchange where in-situ repair is not the fastest path. Components routinely serviced include nacelles, thrust reversers, engine cowlings, radomes, and flight control surfaces across all common narrowbody and widebody types. For GCC operators whose desert operating environment — UV exposure, sand abrasion, thermal cycling — generates higher composite wear rates than temperate climates, this breadth of in-house repair authority is operationally significant.
