Abstract: Methods of manufacturing composite workpieces that include adding an expandable element to an internal volume of a constraining container proximate to a uncured composite workpiece supported on a rigid form, where the expandable element is configured to expand when a predetermined change is produced in an attribute of the expandable element; expanding the expandable element by producing the predetermined change in the attribute of the expandable element, so that an expansion of the expandable element applies pressure to the workpiece supported on the rigid form within the internal volume, and curing the composite workpiece while the resulting pressure is applied to the workpiece supported on the rigid form.

Abstract: Provided are a manufacturing device and a molding method for a rotary-component reinforcement carbon fiber reinforced plastic, the manufacturing device molding a ring comprising a carbon fiber reinforced plastic for reinforcement of a rotary component having a circular cross section as an outermost layer of the rotary component, wherein, in a mold in which a unidirectional prepreg comprising a thermosetting resin and carbon fibers and being wound on the rotary component is heated and cured, an annular pressure source, which applies a desired external pressure to the unidirectional prepreg utilizing its own thermal expansion, exists between a cavity of the mold and the unidirectional prepreg. The manufacturing device and molding method are adaptable to mass production, exhibit an excellent mass productivity with inexpensive facilities, enable a low manufacturing cost because of the unnecessity of a disposable secondary material and the repetitive reuse of a member to be used, and are capable of evenly applying a molding pressure in a central direction of the rotary component.

Abstract: A molding apparatus reduces waviness or deformation of fibers. The molding apparatus includes a fiber feeder (7) that feeds fibers (5) to a lamination area (32) long in a first direction, a resin composition feeder (11) that feeds a resin composition (9) to the lamination area (32), an impregnator (17) that impregnates the fibers (5) fed to the lamination area (32) with the resin composition (9), a curing accelerator (13) that accelerates curing of the resin composition (9) fed to the lamination area (32) while the fibers (5) fed in the lamination area (32) are being tensioned, and a transporter (15) that relatively moves the devices (7, 11, 17, and 13) in the first direction with respect to the lamination area (32). The resin composition (9) contains an epoxy resin (A), a cyanate resin (B), and an aromatic amine curing agent (C) that is liquid at 25° C.

Abstract: The pipe structure according to the present invention includes: a fiber-reinforced plastic pipe 5; moisture-proof foils 11, 12 which individually cover an outer circumferential surface of the pipe 5 and an inner circumferential surface thereof; and an intermediate part 4 which is made of metal and fitted to an end of the pipe 5, wherein end portions of the moisture-proof foils 11, 12 are tightly sandwiched between the pipe 5 and the intermediate part 4. This configuration reliably prevents an FRP pipe from absorbing moisture, and thus, prevents the FRP pipe from shrinking due to moisture exhaustion in outer space, whereby it is possible to obtain the pipe structure having excellent dimensional stability.

Abstract: A method of manufacturing a skate boot shell, and more particularly a non-lasted skate boot shell, including shaping tridimensional outer and inner sub-shells, and bonding the shaped sub-shells together through lamination. The lamination is performed after the sub-shells are shaped and includes applying heat to the sub-shells and/or pressure on one of the sub-shells toward the other against a mold surface. A skate boot shell with multiple sub-shells is also discussed, including an outer sub-shell, and inner sub-shell and a reinforcement sub-shell.

Abstract: There is disclosed a method of manufacturing a composite component. A preform for the component is laid-up on a lay-up tool so that a first surface of the preform conforms to a lay-up profile of the tool. The preform is transferred to a forming tool comprising opposing first and second forming surfaces, each having a near net shape profile corresponding to a respective side of the component. The preform is formed in the forming tool to a near net shape of the component. The preform has a preform bulk in excess of the near net shape of the component prior to forming, and the lay-up profile is offset relative to the near net shape profile of the first forming surface to accommodate a proportion of the preform bulk. Accordingly, both the first surface and an opposing second surface of the preform displace during forming to conform to the respective near net shape profiles of the forming surfaces.
