Abstract
A wood composite board or panel, such as particleboard, fiberboard, oriented strand board or waferboard and a method of producing the same. The composite board or panel comprises a plurality of wood pieces, thermoset resin to bind the wood pieces and a filler having a high thermal conductivity. Examples of such a filler include natural and synthetic graphites, metal, carbon, silicon carbide and other similar compounds and their mixtures.

A method of reducing press time in the manufacture of a wood composite, the method comprising:
- mixing a thermoset resin, a plurality of wood pieces and a filler to form a mixture, each of the thermoset resin, wood pieces and filler having a thermal conductivity, the thermal conductivity of the filler begin greater than the thermal conductivity of the thermoset resin and the thermal conductivity of the wood pieces;
- and
- hot pressing the mixture for a sufficient amount of time to form said wood composite board, the amount of time being less than an amount of time required to hot press the same mixture when no filler is used.
A method of manufacturing a wood composite, the method comprising:
- mixing a thermoset resin having a thermal conductivity and a plurality of wood pieces having a thermal conductivity to form a blend;
- adding a filler having a thermal conductivity to said blend to form a mixture, the filler having a thermal conductivity greater than the thermal conductivity of the resin and the wood pieces;
- placing said mixture in a shaped container;
- and
- applying elevated temperature and pressure to said mixture in said container to form said wood composite board, the method having a press time that is less than a press time required for the same method when no filler is used.
A method of manufacturing a wood composite, the method comprising:
- mixing a thermoset resin, a plurality of wood pieces and a filler comprising particles having lengths to form a mixture, such that the particles are mixed substantially non-unidirectionally within said resin;
- and
- hot pressing the mixture for a sufficient amount of time to form said wood composite board.
