Abstract

Method for manufacturing a wood composite, comprising the steps of providing an reactive composite mixture (4) by mixing a reactive binder and vegetable fibres; supplying the reactive composite mixture to an extruder (5), discharging of the composite mixture from the extrusion device via an extrusion discharge (6) to a curing mould (8); filling the pores of the vegetable fibres with the reactive binder while simultaneously expensing the air from the pores at extrusion process conditions; reacting of the reactive binder around the vegetable fibres and in the pores of the vegetable fibres into a wood composite at the temperature of the extrusion process conditions.
