ADVANCED ENGINEERING RESIN AND WOOD FIBER COMPOSITE

摘要

The invention relates to a composition comprising an engineering resin and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members. The resin/wood fiber composite structural members can be manufactured in an extrusion process or an injection molding process. The linear extrudate or pellet can have a cross section of any arbitrary shape, or can be a regular geometric shape. The pellet can have a volume of at least about 12 mm3. Preferably the pellet is a right cylindrical pellet having a minimum radius of about 1.5 mm and a minimum length of 1 mm weighing at least 14 mg. The invention also relates to the environmentally sensitive recycle of waste streams. The resin/wood fiber composite can contain an intentional recycle of a waste stream comprising polymer flakes or particles or wood fiber. The waste stream can comprise, 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.
