Segment Insights & Market Share Analysis of the Pultruded Spar Cap Market:

The global Pultruded Spar Cap Market is segmented based on Resin type, Fiber Reinforcement type, Shore type, and region.

Based on Resin Type

Vinyl ester resin is expected to remain the largest and fastest-growing resin of the market during the forecast period.

  • Based on the resin type, the pultruded spar cap market is segmented into epoxy resin, vinyl ester resin, and other resin.
  • Vinyl ester performs better than epoxy composites under tension and offers greater resistance. This ensures the structural integrity of pultruded components, making them more suitable for demanding wind turbine applications.
  • However, polyurethane composite is also gaining traction in the market, especially in Europe, as it offers improved bending strength and higher interlaminar shear strength than vinyl ester and epoxy.
  • However polyurethane one of the other resins also improves productivity, mainly due to its low viscosity and high reactivity, which, in turn, reduces the production cost of pultruded spar caps when compared with vinyl ester and epoxy composites.

Based on Fiber Type

CFRP is expected to maintain its supremacy in the market as the fastest-growing fiber type during the forecast period.

  • Based on the fiber type, the market is segmented into CFRP and GFRP & Hybrid.
  • With the ongoing trend of increasing wind blade lengths to enhance wind power, incorporating carbon fiber for making plates for spar caps has emerged as an effective strategy to improve the strength-to-weight ratio and enhance blade rigidity.

Based on Shore Type

Offshore is expected to be the faster-growing shore of the market during the forecast period.

  • Based on the shore type, the market is segmented into onshore pultruded spar caps and offshore pultruded spar caps.
  • Due to the challenging environment and harsh conditions faced by offshore installations, the incorporation of pultruded spar caps offers notable advantages, such as corrosion resistance, durability, lightweight design, and structural integrity.
  • Offshore wind turbine blades are now increasingly being developed with carbon fiber pultruded spar caps, as carbon fiber's high strength allows spar caps to distribute loads effectively, reducing material stress and extending the overall fatigue life of the blade.
  • Offshore wind turbines typically experience higher and more consistent wind speeds compared to onshore locations. The lightweight yet strong nature of carbon fiber pultruded spar caps contributes to maximizing energy yield from offshore installations.

Which region shows the most promising growth forecast and opportunity?

The analysis suggests that Asia-Pacific is the biggest market for Pultruded spar cap during the forecast period. This growth outlook is mainly attributed to the following:

  • In terms of regions, Asia-Pacific is the biggest market and is likely to grow at the fastest rate over the coming years, driven by an expected increase in offshore turbine installations and emerging opportunities for carbon fiber pultruded spar caps. Vestas has formed cooperation with a few local players, Weihai Guangwei Composites Co., Ltd. and Jiangsu Aosheng Composite Material Technology Co., Ltd., for the supply and development of pultruded spar caps in the region. China is likely to remain the key growth engine of the market, as the country is the largest wind turbine installer in the world and has the presence of many leading wind turbine manufacturers.
  • Europe is the second-largest offshore wind turbine installer in the world. This region has a presence of major OEMs, such as Vestas, Siemens Gamesa, Nordex SE, Enercon GmbH, and General Electric Company. Exclusive supplier agreements by these OEMs with leading pultruded spar cap manufacturers like Zoltek Corporation, Fiberline Composites, and DowAksa, will bolster healthy growth in the market over the years.
