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： An optical forming device includes a light source to emit light for causing liquid photocurable resin to undergo curing and an optical modulator to modulate the light for causing the liquid photocurable resin to undergo curing in a pattern based on a shape of a three-dimensional object, and irradiate the liquid photocurable resin with the modulated light. The optical modulator includes a liquid crystal device to modulate the light for causing the liquid photocurable resin to undergo curing in the pattern, and emit the modulated light as linearly polarized light and an optical retardation device to impart a phase difference to the linearly polarized light emitted from the liquid crystal device, and emit the light imparted with the phase difference.

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.

摘要： An example method for curing a composite part includes placing the composite part onto a topside of a cure tool, and a bottom surface of the composite part contacts the topside of the cure tool and a top surface of the composite part is opposite the bottom surface of the composite part. The method also includes placing the cure tool and the composite part into an autoclave, using the autoclave to apply external heat to the cure tool and the composite part so that air flows over the top surface of the composite part to heat the top surface, and applying additional heat to a backside of the cure tool via radiation provided by at least one heating source of the cure tool, so as to reduce a temperature difference between the backside of the cure tool and the top surface of the composite part being cured.
