Carbon pultrusion

Longer and stronger blades

Fiberline Composites' pultruded carbon fibre profiles help to strengthen constructions in some of the world’s longest wind turbine blades

Pultruded carbon spar caps

Fiberline Composites’ pultruded carbon profiles are engineered to purpose and manufactured to fit the specific requirements desired by our customers.


Pultrusion is the most cost effective way of converting carbon fibres into profiles. The continuous process ensures products with a minimum of variation and superior mechanical properties that save significant amounts of material.


Our carbon pultrusion lines run 24/7 and we have a capacity of several thousand tons per year.
