ADVANCED ENGINEERING RESIN AND WOOD FIBER COMPOSITE

摘要

The invention relates to a composition comprising an engineering resin andwood fiber composite that can be used in the form ofa linear extrudate or thermoplastic pellet to manufacture structural members.The resin/wood fiber composite structural members can bemanufactured in an extrusion process or an injection molding process. Thelinear extrudate or pellet can have a cross section of any arbitraryshape, or can be a regular geometric shape. The pellet can have a volume of atleast about 12 mm3. Preferably the pellet is a right cylindricalpellet having a minimum radius of about 1.5 mm and a minimum length of 1 mmweighing at least 14 mg. The invention also relates to theenvironmentally sensitive recycle of waste streams. The resin/wood fibercomposite can contain an intentional recycle of a waste streamcomprising polymer flakes or particles or wood fiber. The waste stream cancomprise, in addition to resin, other thermoplastics fibers,adhesive, paint, preservative, or other chemical stream common in the wood-window or door manufacturing process, or mixtures thereof.
