Composite solutions for the wind industry
Rotor blades and other components of modern wind turbines have to withstand extreme loads - with increasing pressure to reduce weight, optimize processes and extend service life. Depending on the component, different requirements come into play: maximum rigidity in spar caps, good drapability in the interlayers or robust structures in the shell section.
SAERTEX has been a trusted partner to the wind industry for many years, providing the right materials – reliable, certified, globally available and always with a focus on your process efficiency.
The overall goal remains the same: making wind energy more economical and increasing the lifetime of wind turbines.

Whether standard or special functional fabrics: we develop reinforcement materials that are precisely tailored to your requirements - including services such as cutting & kitting and certified laboratory tests.
Proven quality for the wind industry
Global strength - local
presence
Application in focus
From the wind turbine blade root to the spar cap: our textile reinforcement materials increase the efficiency, stability and service life of the blades. Regardless of the area of the blade - we offer the right solution for higher performance and more economical production.
Nacelle
Fiber-reinforced textiles protect valuable components and reduce weight - robustly and cost-effectively.
Root section
Textile reinforcement materials increase the load-bearing capacity of the root section and ensure a durable connection.
Lightning protection
Carbon layers in lightning protection systems protect rotor blades from damage due to their electrical conductivity.
Spar cap
UD fabrics made of carbon or glass fibers offer maximum stiffness and efficient load absorption.
Interlayer
Carbon or glass-carbon hybrid fabrics as interlayers support the impregnation and ensure the electrical conductivity of the pultrusion belts of rotor blades.
Shell
SAERfoam as a structural core material reduces weight and costs - a cost-effective alternative to high-density PET & balsa.
Shear web
Composite materials in the shear web ensure high torsional strength and low weight.
Trailing Edge
Our Easy Drape UD enables a wrinkle-free layup even in highly curved molds.
Areas of application in the wind industry
Onshore wind turbines
Efficient reinforcement materials for high quantities, fast cycle times and stable processes in series production.
Offshore wind turbines
Robust glass and carbon solutions with high fatigue strength and resistance to extreme environmental conditions.
Material developments for optimized processes
In order to meet the increasing requirements for stiffness, design and cost competitiveness of rotor blades, we use many new material developments from SAERTEX in addition to the proven fabrics made of E-glass, high-modulus glass and carbon.
The wave-free UD fabric enables processing speeds up to 15% faster and increases tensile strength by around 20% - efficiency in perfection. The result: shorter cycle times, higher component quality, and significant cost advantages - ideal for spar caps and trailing edges.
Developed for component thicknesses of up to 140 mm, this carbon UD fabric enables up to 3.5× faster resin infusion - high-performance for thick laminate structures. The result: shorter cycle times, outstanding mechanical properties and high drapability - ideal for rotor blade spar caps and industrial applications.
Specially developed for laminate thicknesses up to 70 mm, this carbon fabric achieves fiber contents of up to 60 %, reduces resin consumption, and increases cost-effectiveness—perfect for thick laminate structures. High drapability, wrinkle-free processing, and excellent flow properties ensure stable component quality.
Multiaxial and unidirectional fabrics are versatile reinforcing materials for fiber-reinforced plastics. They are used in many industries wherever lightweight yet resilient components are required.
Optimized for the requirements of the wind industry. The core material with 3D glass fiber reinforcement offers shear stiffness comparable to balsa. Industrial manufacturing ensures consistent properties and proven process reliability in the processing of rotor blade shells.
DNV-certified quality for your wind applications
The independent DNV certification confirms that our materials meet the highest requirements of the wind industry. It stands for proven safety, consistent quality and reliable performance, even in highly stressed components such as rotor blades. This creates a reliable basis - for safe and high-performance wind power solutions.
