  • Patent number: 10328610
    Abstract: The method of recycling carbon fiber prepreg waste includes collecting uncured carbon fiber prepreg waste, where the carbon fiber prepreg waste still includes the backing film associated with the carbon fiber prepreg (typically in the form of a colored polyethylene layer). The uncured carbon fiber prepreg waste is then shredded and inserted into either an open or a closed mold. The mold is then inserted into a hot press, where the shredded carbon fiber prepreg waste is cured under selected temperature and pressure for a selected period of time, dependent upon the particular volume of waste and the desired recycled product. Alternatively, the shredded carbon fiber prepreg waste may be rolled in a hot metallic roller or extruded in a hot melt extruder.

  • Publication number: 20100267868
    Abstract: The present invention provides a method of recycling a fiber-reinforced plastic by which a recycled material of a fiber-reinforced plastic having excellent strength properties can be obtained. The method is a method of recycling a fiber-reinforced plastic comprising carbon fibers and a thermosetting resin (epoxy resin), comprising a first step of producing a harmless material by subjecting a fiber-reinforced plastic B to heat treatment so as to burn off an epoxy resin and a second step of applying a sizing agent to or spraying a sizing agent over the harmless material, producing a strip-shaped harmless material B?, and producing a recycled material containing short carbon fibers during kneading of the strip-shaped harmless material B? and a thermoplastic resin (polypropylene).

  • Publication number: 20020091179
    Abstract: Flexible, semi-rigid, and rigid vinyl chloride polymer compositions containing a heat stabilizer comprising a latent mercaptan and a mixture of zinc chloride and a zinc carboxylate are substantially free from the offensive odor typically associated with mercaptans and are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan which include a free mercaptan. The free mercaptan thus released enhances the activity of the mixture of zinc chloride and zinc carboxylate.

  • Patent number: 5474522
    Abstract: The present invention provides an article, comprising: a fabric sheet; a curable resin coated onto the fabric sheet; and a plurality of microfiber fillers dispersed into the resin. The incorporation of microfiber fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material, particularly when the fabric used therein is a non-fiberglass fabric, while not detracting from the handling properties of the uncured casting tape or bandage.The microfiber fillers useful in this invention are generally characterized as being short fibers having an aspect ratio greater than five to one. Blends of microfibers having different aspect ratios may be utilized in the casting tapes of the present invention. Preferred microfiber fillers or blends have an aspect ratio between 5:1 and 200:1, more preferably, the aspect ratio of the microfiber is between 5:1 and 50:1, and most preferably, the aspect ratio of the microfiber is between 10:1 and 30:1.
