Pultruded carbon planks are used as a reinforcing element inside the rotor blades of wind turbines.

The use of carbon fibre guarantees high quality components and the best possible mechanical properties, as the blades must be able to support high loads for the entire life of the equipment.

DESCRIPTION
TECHNICAL FEATURES

The pultrusion process of our planks allows stability and constant quality assurance during the production of large quantities.

Elastic modulus between 140 GPa and 280 GPa
Exceptional stiffness-to-weight ratio
Dimensional stability and arrangement of the composite
Chemical corrosion resistance
Resistance to saline environments
Vibration absorption
High electrical conductivity
Packaging in rolls starting from 50 meters

Carbonveneta is among the European leaders in this market segment and produces laminates, planks and plates of various thicknesses, widths and roll lengths. Standard planks have an Elastic Modulus normally between 140 GPa and 280 GPa, while for special projects they can be produced with dedicated yarns thus obtaining the desired Elastic Modulus.

Until a few years ago, with turbines having blades 10-15 meters long, fiberglass was commonly used while today, with blades of off-shore turbines which can even reach 130 meters in length, it is indispensable use of carbon fibre, which guarantees high quality components and the best possible mechanical properties, as the blades must be able to support high loads for the entire life of the equipment.

APPLICATIONS

• Wind energy: wind turbines are systems that collect and convert the kinetic energy in the wind to produce mechanical energy or electrical power. It has been highlighted that in order to intercept a greater quantity of energy contained in the wind, the turbine must be as large as possible. The trend in the last decades of development is to make ever longer blades, with the length in the case of off-shore turbines which can even reach 130 meters.
