Irradiation method for production of fiber-reinforced polymeric composites
Abstract
Abstract A METHOD IS PROVIDED FOR IRRADIATING MATERIAL ON A CONTINUOUS BASIS TO IMPROVE OR PREDETERMINATELY CHANGE ITS PHYSICAL AND CHEMICAL CHARACTERISTICS. IN ONE FORM, POLYMERIC MATERIAL IS CONTINUOUSLY FORMED BY EXTRUSION AND IS CONTINUOUSLY COMBINED WITH OR SEALED TO A SECOND MATERIAL TO FORM AN INTEGRAL UNITARY STRUCTURE THEREWITH AFTER WHICH SAID UNITARY STRUCTURE IS DRIVEN AND GUIDED IN A PREDETERMINED PATH THROUGH A FIELD OF INTENSE RADIATION WHICH IS OPERATIVE TO CHANGE THE PHYSICAL CHARACTERISTICS OF ONE OR MORE OF THE COMPONENTS OF THE COMPOSITE MATERIAL SUCH AS BY EFFECTING THE CROSS LINKING OF THE POLYMER. IN ANOTHER FORM, A MATERIAL SUCH AS A POLYMER IS CONTINUOUSLY FED OR FORMED INTO A SHEET OR OTHER SUITABLE SHAPE AND A PLURALITY OF REINFORCING ELEMENTS SUCH AS GLASS FILAMENTS ARC ENCAPSULATED WITHIN THE POLYMER OR OTHERWISE SECURED THERETO ON A CONTINUOUS BASIS. THE RESULTING COMPOSITE FILAMENT-REINFORCE MEMBER IS THEREAFTER TREATED TO EFFECT THE CROSS LINKING OF THE POLYMER TO IMPROVE ITS PHYSICAL CHARACTERISTICS AND TO IMPROVE THE BOND BETWEEN THE POLYMER AND THE REINFORCING FILAMENTS.
