ABSTRACT:
A composite cellulose fiber reinforced polyolefin is enclosed. The polyolefin is manufactured by a process that includes preparing and mixing a blend of molten polyolefin, a coloring concentrate and a coupling agent in a kneading extruder, preheating cellulose fibers in an enclosed cram feed and mixing the blend of polyolefin, preheated cellulose fibers and ozone gas in a ozone chamber to form a polyolefin and fiber matrix. The polyolefin and fiber matrix is then fed to a twin screw extruder where it is further heated, mixed and then conveyed to a die to extrude the mixer to a desired shape.
