摘要： A composite laminate heating tool broadly comprising a substructure, a facesheet, and number of expansion joints. The substructure supports the facesheet but does not need to have the same or a similar CTE as the facesheet because the facesheet is free to expand relative to the substructure. The expansion joints provide an interface between the facesheet and the substructure so that the facesheet can thermally expand relative to the substructure while being fully supported by the substructure. Each expansion joint includes a guide attached to the substructure and a support member translatable relative to the guide and aligned radially from a centroid or center of expansion of the facesheet so as to have a single degree of freedom.

摘要： A temperature control apparatus includes a temperature control branch connected to a feed line for a temperature control medium, a pump system including a pump for conveying the medium, a pump open-loop or closed-loop control device for controlling the output of the pump system, a throttle device having a variable degree of opening for throttling a quantitative through-flow of the medium in the temperature control branch, and an open-loop or closed-loop control device with the degree of opening of the throttle device as a setting value and with a control variable from the group: degree of opening of the throttle device, temperature, temperature difference, through-flow, pressure or a physical value to be derived from that group. The pump open-loop or closed-loop control device is configured to control an operation of the pump to adjust the delivery output of the pump system depending on the degree of opening of the throttle device.

摘要： A heat blanket system including a blanket including a first sub-area and a second sub-area. The heat blanket system also includes heating elements printed on the blanket. First spacings between first ones of the heating elements in the first sub-area varies relative to second spacings between second ones of the heating elements in the second sub-area. The first spacings and the second spacings vary according to a design. The design is configured for use on a uniquely defined rework area on a uniquely defined composite material object including a third area including a heat sink region and a fourth area including a non-heat sink region. The first sub-area is sized and dimensioned to be placed over the third area. The second sub-area is sized and dimensioned to be placed over the fourth area.

摘要： An optical forming device includes a resin tank that is to retain a photocurable resin containing dichroic polymerization initiator and a light emitter to emit light for causing the photocurable resin to undergo curing. An alignment film for causing the dichroic polymerization initiator to align in a predetermined direction is provided on a bottom portion of the resin tank. The light emitter irradiates the photocurable resin with the light by passing the light through the bottom portion of the resin tank as linearly polarized light having a polarization direction in a direction perpendicular to a direction in which the dichroic polymerization initiator is aligned by the alignment film.

摘要： A system for fusing thermoplastic composite structures includes a skin and a substructure on an inner surface of the skin. The system also includes a shaping surface of a tool, with the skin laid up on the shaping surface. The shaping surface is configured to maintain the shape of an outer mold line. The system further includes at least one insulation layer applied over a flange of the substructure and over exposed portions of the inner surface of the skin not in contact with the substructure, and a vacuum bag at least partly enclosing the skin and the substructure. Heat can be applied to the shaping surface to fuse the substructure to the skin such that the skin exceeds its melting point and at least a portion of a raised segment of the substructure does not exceed its melting point.

摘要： [Abstract] A polymerization apparatus according to an embodiment of the present invention includes: a light irradiator; and a polymerization vessel. The light irradiator includes a first casing and a light source assembly. The first casing includes a light source chamber defined by cylindrical side walls, a ceiling, and a floor including a light-transmissive window member. The light source assembly includes a base having a light-emitting surface on which a plurality of light-emitting diodes is disposed in a predetermined pattern and a heat-dissipating surface to which a heat sink is joined, and the light source assembly is disposed within the light source chamber so that the light-emitting surface faces the light-transmissive window member. The polymerization vessel includes a polymerization cup and a second casing. The polymerization cup has a frustoconical or substantially frustoconical shape that opens upward and increases in diameter upward, and is capable of housing an object therein. The second casing is a bottomed cylindrical or box-shaped casing having an opening at the apex thereof, the polymerization cup being attachably/detachably housed in the second casing via the opening. In this polymerization apparatus, light that has been emitted by the plurality of light-emitting diodes of the light irradiator and has passed through the light-transmissive window member is applied to the inside of the polymerization cup of the polymerization vessel.

摘要： Embodiments relate generally to a traction surface and methods for forming the traction surface. The traction surface may comprise a compound material comprising glass fibers oriented orthogonal to the surface of the compound material extending from the compound material, wherein when the traction surface contacts an icy surface, the glass fibers are operable to penetrate a liquid-like top layer of the icy surface to provide grip with an ice layer below the liquid-like top layer. The method for forming the traction surface may comprise integrating glass fibers into a compound material; orienting the glass fibers within the compound material such that the glass fibers are oriented approximately orthogonal to the surface of the compound material; splitting the compound material to expose the glass fibers, wherein the glass fibers extend from the surface of the compound material; and forming the split compound material into a traction surface.
