The pultrusion process.
In the pultrusion process, the reinforcing fibres and mats (1) are guided into the pultrusion die (2). The resin-impregnated reinforcing fibres enter the heated die where they are cured and pulled evenly out of the die via the haul-off unit (3). Finally, the “travelling saw” (4) cuts the section to the desired size.
In the pultrusion process, we can control a wide variety of different
properties of a fibre-reinforced composite section:
- Mechanical properties, e.g. strength and stiffness
- Colour and paintability
- Surface condition
- Resistance to weathering and UV
- Chemical resistance
- Electrical and thermal insulation
- Behaviour in fire
