Patent number: 10328610Abstract: 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.Type: GrantFiled: August 18, 2017Date of Patent: June 25, 2019Assignee: United Arab Emirates UniversityInventors: Waleed K.

Publication number: 20100267868Abstract: 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).Type: ApplicationFiled: December 8, 2008Publication date: October 21, 2010Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, KOJIMA SANGYO KABUSHIKI KAISHAInventors: Naoyuki Takahashi, Tetsuji Nagase
