Carbon Fiber Knowledge
The latest from the world of advanced composites and carbon fiber technology.
Hydrogen storage is the quiet bottleneck of the hydrogen economy. Electrolyzers, fuel cells and compressors attract attention because they are new subsystems with dramatic cost curves, but every hydrogen vehicle, refueling station and mobile power unit still needs a pressurized vessel,
Onshore blade repair is a workshop problem: the blade comes down, the damage is assessed on the bench, and the repair is made under a roof with lights, power and stable temperature. Offshore, none of that holds. The blade stays on the turbine — transport costs and crane availability mak
Every carbon fiber that flies in a commercial or military aircraft arrived there through a qualification chain that few outside the industry see. A fiber lot is not certified; a part is. The chain runs from raw fiber lot to prepreg lot, to test laminate, to subcomponent, and finally to
Adhesive bonding has been the default joining method for wind turbine blades for decades, and for good reason: it is forgiving, tolerant of manufacturing tolerances, and works across dissimilar materials. But it is also heavy. The adhesive layer in a large blade can run thick enough to
Wind blade cost models are built on one uncomfortable fact: the material that makes blades light is also the material that makes them expensive. Early 2026 market data put high-performance carbon fiber sheet prices at $160-320 per square meter — a range that has held through the year as
Turkey is the geographic hinge of the composites market between Europe and the Middle East — close enough to European OEM supply chains to ship components in days, and close enough to Gulf and North African project markets to act as a manufacturing bridge. For two decades its composite
Erosion of the leading edge is the quiet drain on wind farm revenue. The edge operates at the highest relative speed of any blade surface, and rain, hail, sand and insects gradually turn its smooth profile into a rough, pitted zone that degrades aerodynamic efficiency for the remaining
The leading edge of a wind turbine blade is the hardest-working sacrificial component on the machine. It takes the first impact of every raindrop, hailstone and dust particle at tip speeds above 70 meters per second, and it is the part most likely to force a repair visit long before the
Spar cap production remains one of the most labor-intensive operations in blade manufacturing. A 100-meter-class spar cap can require hundreds of hours of hand layup: manual placement of pultruded carbon plates or prepreg stacks into a multi-meter mold, followed by vacuum bagging, infus
