Embodiments of the invention include a composite. The composite includes a crystalline polymer, a plurality of wood fibers blended with the crystalline polymer, an outer surface, and an amorphous polymer visible on the outer surface. The amorphous polymer has a first color and the blend of the crystalline polymer and the plurality of wood fibers has a second color different from the first color. The invention also includes a method of manufacturing the wood-plastic composites such that one polymer is shifted in the composite relative to the other polymer.
L'invention concerne, dans des modes de réalisation, un composite qui comporte un polymère cristallin, plusieurs fibres de bois mélangées au polymère cristallin, une surface extérieure, et un polymère amorphe visible sur la surface extérieure. Le polymère amorphe présente une première couleur et le mélange du polymère cristallin et la pluralité de fibres de bois une seconde couleur différente de la première couleur. L'invention concerne également un procédé de fabrication des composites bois-plastique de façon qu'un polymère soit déplacé dans le composite par rapport à l'autre polymère.
