Abstract
Composite material and plunger-cast pipe manufacturing method and system wherein the composite material includes waste, chemically unmodified PET material, one or more waste filler materials (e.g. rock crusher fines, lime sludge or waste coal combustion by-products), and fiber reinforcement (e.g. glass, metal, ceramic, carbon, organic, and polymer fibers) and wherein the PET material is melted and mixed in a container to disperse filler material and fiber reinforcement in the PET material. The resulting mixture can be formed into a tubular pipe shape using the plunger-cast manufacturing method and system wherein a plunger piston and inner collapsible mold are pushed into the melted composite material contained in an outer mold. When cooled and solidified in the mold, a composite material having a matrix comprising PET with filler material and fiber reinforcement distributed in the matrix is formed in the shape of a tubular body.
