Method for manufacturing a wood composite

A method for manufacturing a wood composite, comprising the steps of:

• providing an amount or a stream of vegetable fibres;
• providing an amount or a stream of reactive, thermosetting binder, the reactive, thermosetting binder including a reactive component and/or a reactive prepolymer;
• mixing the reactive binder and the vegetable fibres into a reactive composite mixture and feeding the reactive composite mixture to an extrusion device;
• subjecting the reactive composite mixture in the extrusion device to extrusion process conditions;
• filling the pores of the vegetable fibres with the reactive, thermosetting binder while simultaneously expelling the air from the pores;
• and
• reacting of the reactive, thermosetting binder around the vegetable fibres and within the pores of the vegetable fibres and forming a wood composite at the temperature of the extrusion process conditions,
• wherein the viscosity of the reactive, thermosetting binder is in the range from about 0.1 to 100 mPa·s at the extrusion process conditions, and
• wherein the extrusion process conditions comprise a temperature in the range of about 100° C.-200° C., and comprise a pressure in the range of about 100-3000 bar.
