  • Publication number: 20240083073
    Abstract: A method and apparatus for recovering fibres from fibre reinforced polymer (FRP) materials uses a thermomechanical process to produce high quality recovered fibres and powdered polymer resin. The thermo- (cryo-) mechanical process uses a combination of a selected range of temperatures and mechanical force, and is chemical and solvent-free, and produces zero waste. Fibre length remains unchanged after processing and mechanical properties of the recovered fibres are comparable to or better than those of virgin fibres. The recovered fibres and powdered polymer resin may be used to make new FRP products.

  • Patent number: 11760639
    Abstract: A method of exfoliating layered, shearable material is described. Examples are provided including exfoliation of graphite to form graphene nanoplatelets. Also described is a machine for preparing nanoplatelets that includes a chamber whose volume can be increased by pressure exerted by the exfoliated product. Composites of graphene nanoplatelets and polyamide exhibited improved flexural modulus compared to that of graphite composites while impact strength was unaffected.
