WIND ENERGY
ROHACRYL™ reduces turbine loads
Our ROHACRYL™ foam core is a product meticulously engineered to fulfill the stringent requirements of the wind energy sector. It offers the essential stiffness, strength and durability needed for composite structures while significantly reducing weight compared to other core materials.
Enabling peak performance
- significant mass reduction
- decreased resin uptake
- unique shaping capabilities
- minimize CoPQ
- mitigate the risk of blade failure
Onshore turbine blades are typically manufactured at lengths of 80 meters or more, whereas offshore turbine blades can exceed 115 meters, with demands continuing to rise. The turbine loads in structures of such magnitude are substantial, leading to stringent structural requirements for all wind turbine components, ranging from the blade bearings to the tower foundation. A blade with reduced weight can significantly decrease the stress on these components, thereby prolonging the life of the turbine.
ROHACRYL™ is instrumental in lowering the overall blade mass and resin costs due to its low density and minimal cell sizes, which reduce resin absorption during the infusion process that creates the finished blade. Utilizing ultra-lightweight ROHACRYL™ foam cores allows blade designers to refine the infusion process, achieving higher quality levels compared to commonly used core materials. This enables the production of high-quality blades of any length that are unparalleled in the industry.
The advantages of ROHACRYL™ sandwich cores provide blade designers with a competitive advantage in crafting lightweight turbine blades, which is crucial for both onshore facilities and the rapidly growing offshore wind energy sector.
LIGHTWEIGHT BLADES PRODUCED WITH HIGHEST EFFICIENCY ROHACRYL™
ROHACRYL's superior mechanical properties allow for the use of much lower densities without compromising strength. Its acrylic composition, coupled with homogeneous, small, and isotropic cell structure, ensures the highest consistency with your design specifications and manufacturing processes. Furthermore, ROHACRYL™'s adaptability opens up a broad spectrum of design possibilities to meet your unique design challenges.
ROHACRYL™ is compatible with all prevalent thermoset and thermoplastic polymers, ensuring outstanding mechanical performance even at lower foam densities. The use of ROHACRYL™ can lead to cost efficiencies in turbine assembly, a reduction in breakaway torque, and weight savings in tower construction, enhancing overall performance. ROHACRYL™ foam is available in nominal densities from 60 kg/m³ - 140 kg/m³. The Product Information describes the properties of ROHACRYL™ structural foam in detail.
