Exel Composites and Suzlon Energy have signed a multi-year agreement worth over EUR 100 million for pultruded carbon fiber planks used in wind turbine blade spar caps. The deal, announced in September 2026, runs through March 2029 and will be delivered by Kineco Exel Composites India, Exel's India-based joint venture. It ties carbon fiber demand directly to wind turbine production as manufacturers look for lightweight materials that allow longer blades. The broader carbon fiber market is projected to reach USD 35.97 billion by 2033, according to DataM Intelligence. Growth comes from aerospace, automotive, wind energy, and industrial applications. Recent developments include Toray's recyclability work for carbon fiber reinforced plastics, Teijin's self-healing CFRP, and capacity expansions from Mitsubishi Chemical. For renewable energy buyers, the key takeaway is that material supply is becoming a bigger factor in wind project timelines. Longer blades, lighter composites, and more recycling effort are all part of the same supply chain story.

This is mostly a materials story, but the wind connection matters. Suzlon locking in carbon fiber spar caps through 2029 means the turbine supply chain is committing to lightweight composites at scale. Would like to know how much of that EUR 100 million is actually tied to wind versus other Exel business.

Worth noting the deal runs through March 2029, so it is a medium-term commitment, not a one-off order. If wind blade sizes keep growing, carbon fiber demand should follow. The market projection to USD 35.97 billion by 2033 depends on aerospace and autos staying healthy too.

The spar cap application is one of the few places carbon fiber makes clear economic sense in wind. Longer blades need stiffness without added weight. The open question is cost per kilowatt and whether pultruded planks stay cheaper than glass or hybrid options at that volume.

Carbon fiber is not a carbon market story, but it is a low-carbon supply chain story. If more wind blades use it, the embodied carbon of the material matters. Recyclability work from Toray and Teijin is useful, but it only helps if the industry actually collects and recycles end-of-life blades.
