SGL Group believe they have achieved a world’s first after Germanischer Lloyd Wind Energy GmbH (GL Wind) approved its 50k heavy tow carbon fibre.
It is thought that the industrial grade carbon fibre, SIGRAFIL C30T050 EPY, is the first and only heavy tow carbon fibre formally approved by GL Wind for use in the wind industry.
In tests, SGL Group was able to demonstrate that the material characteristics and fatigue behaviour of laminates using SIGRAFIL C30T050 EPY fibre are comparable to those of 24k aerospace grade fibre.
The fatigue properties exceed the minimum values given by GL Wind’s “Guideline for the certification of wind turbines”.
The product, SIGRAFIL C30T050 EPY, is a 50k, PAN based carbon fibre designed for industrial applications and is already used in the wind industry. SGL Group offers the fibre as well as semi-finished products like prepreg and dry non crimped fabrics.
All products are specifically designed for use in wind turbine rotor blades.
