Disclosed herein is a composite piston pin including a pipe-shaped outer layer made of reinforced fibers; an inner layer coupled to the outer layer along an inner surface of the outer layer, and made of reinforced fibers having lower elasticity than the outer layer; and a resin material including an epoxy resin composition and cyanate ester, and impregnated into the reinforced fibers of the outer layer and the inner layer.

A fiber reinforced resin hollow molded body 30 in which a resin-integrated fiber sheet is used. The resin-integrated fiber sheet includes unidirectional continuous fibers that are spread fibers of a continuous fiber group and arrayed unidirectionally in parallel, and thermoplastic resin that is present at least on a surface of the unidirectional continuous fibers. In the hollow molded body, in a state where the resin-integrated fiber sheet or a plurality of the resin-integrated fiber sheets 30 are stacked, the resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are wound to produce a wound body having an overlapping portion. The thermoplastic resin is impregnated in the unidirectional continuous fibers. The resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are consolidated.

In a method for manufacturing a high-pressure tank, a fiber bundle impregnated with a thermosetting resin base material is wound around an outer surface of a liner in a state where tension is applied to the fiber bundle in a filament winding step. The filament winding step includes a pressure-bonding step and a cutting step. In the pressure-bonding step, a terminal end portion which is a winding end of the fiber bundle is thermocompression-bonded to an outer peripheral portion of the fiber bundle wound around the liner. In the cutting step, a surplus portion of the fiber bundle is cut by a cutting tool.

Structures for use in forming products having a wood grain appearance include, for example, a plurality of extruded layers having different colors/shades spirally wound about a longitudinal axis to an outer surface to define the structure. The plurality of extruded layers include varying thicknesses along a spiral length of the plurality of layers and/or portions of the plurality of extruded layers encircling the longitudinal axis include portions disposed at different distances from the longitudinal axis. In some embodiments, the spirally winding includes forming a cylindrical structure, and pressing the cylindrical structure into a cuboid structure having a square or rectangular cross-section across the longitudinal axis and at least a portion of the plurality of extruded layers defining a square or rectangle pattern across the longitudinal axis. Longitudinal portions may be cut from the structures to form the products having a wood grain appearance.

A method of manufacturing a medical component includes molding a first member of the medical component from an elastomeric material. The first member includes a first end defined by a closed base wall, an opposing second end which is an open end, a sidewall extending between the first and second ends, and an internal recess to receive at least one electronic device. The method further includes positioning the electronic device within the recess of the first member to form an assembly, such that the electronic device is received in an inverted open cavity defined by the sidewall. The method further includes applying a protective film on the second end of the first member, such that the protective film covers an exposed surface of the electronic device. In addition, the method includes overmolding the assembly with the elastomeric material to form the medical component having the electronic device embedded therein.

Sheet comprising a flexible support and a coating at least partially covering at least one face of the support, the support being made of a support material exhibiting dielectric properties, the coating being made of a coating material different from the support material and exhibiting magneto-dielectric properties or dielectric properties.

A method of manufacturing a medical component includes preparing a first sheet of an elastomeric material, arranging at least one electronic device in the first sheet of elastomeric material to obtain an elastomeric preform, and arranging the elastomeric preform in a mold and molding the elastomeric preform therein to cure the elastomeric material and form the medical component having the at least one electronic device embedded therein.

A winding apparatus for the production of power storage devices comprising: a frame, a first actuator device supported by the frame and comprising a rotor and a first drive element, a support which is driven in rotation by the first actuator device through the first drive element, a second actuator device comprising a second drive element and a non-circular core on which to wind a material; said core being arranged on the support in a rotary manner and being driven in rotation by the second actuator device through the second drive element. The second drive element passes at least partially through the rotor.

Provided is a method for manufacturing a tank and a manufacturing device thereof that can achieve resin impregnation within a short time. The method wraps fibers in an overlapping manner in a radial direction around an outer surface of a liner such that a first fiber layer (braiding layer) on an outer surface of a dome portion is less dense than a second fiber layer (helical layer) on an outer surface of a straight body portion and such that a portion of a lamina of the first fiber layer, which is less dense, is interposed continuously from the first fiber layer partially between laminae of the second fiber layer, and then impregnates the fiber layer including the first fiber layer and the second fiber layer with a resin.

A method for protecting a surface portion is disclosed. The method includes providing an adhesive layer on a surface of a protective layer, the adhesive layer having a first surface that is adhered to the surface of the protective layer, providing an uneven second surface to the adhesive layer, the uneven second surface disposed on an opposite side of the adhesive layer as the first surface, and attaching the protective layer to the surface portion by attaching the uneven second surface of the adhesive layer to an uneven surface of the surface portion.
