Plastic composite with wire reinforcements
Abstract
Abstract A WIRE FIBER REINFORCED PLASTIC COMPOSITE IS FORMED FROM A STYRENE TYPE RESIN SUCH AS POLYSTYRENE OR ACRYLONITRILE-BUTADIENE-STYRENE (ABS) RESIN AND THIN FERROUS METAL WIRES OR FIBERS. THE FERROUS WIRES OF FIBERS ARE PREVENTED FROM CORRODING AT THE SURFACE OF THE PLASTIC BY THE PROVISION OF EITHER SACRIFICIAL WIRES FORMED T METAL SUCH AS ZINC, OR ALTERNATIVELY, FERROUS WIRES COATED WITH A SACRIFICIAL METAL SUCH AS ZINC. THE FERROUS WIRES ARE PREVENTED FROM CORRODING IN THE INTERIOR OF THE COMPOSITE BY A TIGHT ADHERENT BOND FORMED BETWEEN THE SURFACE OF THE FERROUS WIRES AND THE STYRENE OR ABS RESIN BY A BINDER OF ABS RESIN BETWEEN THE FERROUS METAL AND THE PLASTIC MATRIX. THE TIGHT BONDING OF THE FERROUS WIRES TO THE MATRIX PLASTIC ALSO ENABLES A VERY SMOOTH SURFACE FINISH TO BE ATTAINED UPON THE FINISHED PLASTIC ARTICLES. IN SOME CASES THE SACRIFICIAL METAL MAY NOT BE INCLUDED IN THE COMPOSITE.
