  • Patent number: 11623415
    Abstract: A resin bath device for wet winding provided herein includes a resin stirring bath and a resin impregnation bath, where a bottom of a side wall of the resin stirring bath is connected to the resin impregnation bath, two ingredient baths are provided at two ends of the resin stirring bath, and a stirring mechanism is arranged inside the resin stirring bath. A resin dipping roller is mounted at a middle of the resin impregnation bath where a pressure roller is mounted at tops of side walls; an electric heating coil is arranged inside a bottom wall of the resin impregnation bath, and an electric heating rod is arranged at an axis of the pressure roller; and wire guide rollers are mounted at two ends of the side wall of the resin impregnation bath.

  • Publication number: 20230017601
    Abstract: The present disclosure relates to a transition method and system from helical winding to hoop winding of composite fibers. The method includes: setting a slip coefficient, and performing iterative calculation forward from an iteration starting point according to an equation set of a winding angle and a center angle of rotation to obtain a winding angle at an iteration termination point; and if the winding angle at the iteration termination point is greater than a first preset angle, adjusting the slip coefficient corresponding to a cylinder body according to the first preset angle, extending a length of a helical winding transition section to a front equator, and starting the hoop winding at the front equator at the first preset angle to complete planning of the helical winding transition section.

  • Patent number: 8491828
    Abstract: The invention relates to a device for producing a toroid-shaped fiber composite product. The device comprises at least two fiber or fiber composite material dispensing units (2, 3), the dispensing units being adapted to place a fiber (4) or a fiber composite material onto the surface of a toroid-shaped mandrel (5); positioning means to effectuate relative movement of the mandrel and the dispensing units during placement of the fiber or fiber composite material. The invention further relates to a method for producing a toroid-shaped fiber composite product, preferably with a concave cross-section, in particular the rim of a bicycle wheel. The method comprises providing a toroid-shaped mandrel, dispensing fibers or fiber composite material from at least two dispensing units, placing the fibers or fiber composite material onto the mandrel while effectuating a relative movement of the mandrel and the dispensing units, and reshaping at least part of the mandrel, preferably by thermoforming.

  • Patent number: 8343750
    Abstract: The invention discloses an Ochrobactrum sp. for degrading TBBPA and its application in environmental remediation. An Ochrobactrum sp. for degrading TBBPA was isolated from the sludge in a high risk area of electronic waste in the invention. The strain is named as Ochrobactrum sp. T, which has been deposited in China Center for Type Culture Collection (CCTCC) on Oct. 28, 2009 with an accession number of CCTCC M209246. Ochrobactrum sp. T obtained in the invention has high degradation capability to TBBPA in environment. The degradation efficiency of the strain achieves 96.2%. The strain could be applied to degrading TBBPA in environmental remediation.
