Fiberline’s working environment sets the standards for the industry.

After careful deliberation, including assessment of health and safety aspects, Fiberline’s founders, Dorthe and Henrik Thorning, chose pultrusion as the method of production when starting the company in 1979.

In the pultrusion method used by Fiberline the matrix material is added by injection. This takes place in a fully enclosed process which keeps evaporation of volatile substances at a minimum.

As the polymerization is exothermic (develops heat itself), energy consumption per unit produced is also extremely low.

How pultrusion works
Pultrusion is a process that enables continuous production of composite profiles with constant cross sections and material properties tailored to specific purposes.

At Fiberline Composites pultrusion takes place by reinforced material continuously being pulled through a guide in which the fibres are precisely positioned in relation to the cross-section of a profile. The fibres are then led through processing equipment where they are impregnated with a matrix material such as polyester.

The combination of fibres and matrix is pulled on through a heater where the profile is cured in its final geometry.

The fully cured profiles are then pulled forward to a saw which cuts the profiles into defined lengths
