  • Patent number: 11407253
    Abstract: A method of manufacturing a rim includes placing at least one braided sleeve on a core dimensioned to define a shape of an internal wall of the rim. The method includes inserting the braided sleeves placed on the core, inside a mold that is dimensioned to define a shape of an external wall shape of the rim. The method further includes injecting a resin inside the mold to contact the mold and impregnate the sleeves and other layers with resin. The method also includes curing the resin to form the internal and external walls of the rim and obtain a cured rim having the core connected thereto. The method further includes removing the cured rim and core from the mold and melting the core to get it out of the rim.

  • Patent number: 11168202
    Abstract: For a fiber compound resin composition, a melt-kneading process is performed together with a base resin 1, a dispersant, etc. without performing a pretreatment through wet dispersion for the purpose of defibration treatment and modification treatment of a fibrous filler 2. As a result, each fiber of the fibrous filler 2 is defibrated from end portions in a fiber length direction, while a dispersant component put in at the same time is more selectively adsorbed to defibrated portions 3 at the end portions defibrated and increased in surface area. As a result, hydrophobization of the defibrated portions 3 is promoted as compared to a non-defibrated portion 4, so that a difference in hydrophobicity is formed in the fiber length direction of the fibrous filler 2. Therefore, even when the fibrous filler 2 is added in large amount, a melt viscosity during molding may be lowered without reducing a strength of a molded article.

Rafts 200 may be connected together and to other components using flexible cables, that may help to accommodate relative movement of the rafts 200, for example through vibration. The rafts 200 are lighter, more compact, and more convenient to handle than conventional electrical harnesses. The rafts 200 may provide a convenient and secure mounting surface for other components/systems of a gas turbine engine, such as EECs and/or fluid pipes.

  • Patent number: 9849931
    Abstract: A method for forming a bicycle frame assembly having a number of elongate tubes is disclosed. A two part mold can be used to form a hollow finish part as part of the assembly. The assembly includes a passage that is defined by the elongate member, a partition, and a bridge. The partition isolates the passage from an interior volume of the elongate tube. The bridge extends in a direction normal to an elongate direction of the passage and defines an inlet and an outlet of the passage. The inlet, outlet, and bridge are generally flush with an exterior surface of the elongate tube and provide a passage that cooperates with a flexible connector, such as a cable tie, for securing supplemental structures, such as brake and shift control cables, to the elongate tube of the bicycle frame assembly.

  • Patent number: 9545780
    Abstract: A method for producing a part made of a composite material, including a skin and at least one stiffener made of strips, which are in turn made of one or more plies of fibers impregnated with a non-polymerized resin. The method includes the steps of: producing a preform of the part by pulling the strips through a die for shaping and positioning the skin and the stiffeners, a polymerization core being provided between a first strip and a second strip prior to the passage thereof through the die; and pressing the resulting preform in a hot press for a duration dt while applying a pressure P and at a temperature T for polymerizing the resin of the strips in the hot press over a pressing length L that is shorter than the length of the panel.

  • Patent number: 9463840
    Abstract: A bicycle component with reinforced structure and a manufacturing method thereof are disclosed. The bicycle component includes a hollow main body and a foam material. The main body is manufactured by stacking plural carbon fiber prepreg layers and provided with a force bearing area. The foam material is disposed on the force bearing area and wrapped by the carbon fiber prepreg layers. Therefore, the present invention improves the structural strength of the bicycle component, lightens the weight of a bicycle made of the bicycle components, and provides a greater controllability of the bicycle.

  • Patent number: 9403302
    Abstract: A fabrication method and a fabrication device capable of fabricating medium-scale mass production parts. The method of fabricating a composite material hollow part includes: holding a tool on a frame using a holding section that maintains a gap between the tool and the frame, placing a prepreg on the tool, covering the tool and the prepreg using a highly stretchable sheet, securing the highly stretchable sheet and the frame with a securing jig so that tension is applied to the highly stretchable sheet from the top portion of the prepreg where the highly stretchable sheet contacts the prepreg at the highly stretchable sheet and the outer periphery of both the tool and the prepreg to the edges of the highly stretchable sheet, thereby forming an enclosed space that houses the tool and the prepreg, and subsequently evacuating the inside of the enclosed space to wrap the prepreg around the tool.

  • Patent number: 9284010
    Abstract: An inverted tube bike frame with bottle opener gusset system is a bicycle frame with the top tube and down tube having a heightened profile with concave sidewalls and a bottle opener gusset strengthening the joint between the seat tube and the top tube. The top tube has a downwardly curved design for added mechanical strength. Other tube-members of the frame have an elongated elliptical cross-section for increased strength and impact damage resistance. The wheel base is wider than that of a standard bicycle adding to forward movement stability and rider comfort. The design of the frame provides added strength and increased frame life with rugged service.
