This invention related to a method of forming a polymer component and comprises blending polymer particles with antioxidant to form a mixture in which the antioxidant coats the polymer particles, irradiating the polymer particles to cross-link the polymer particles therein and forming the irradiated mixture into a consolidated component. The invention also relates to a method of forming an articular surface for a prosthesis and a prosthesis having a polymer articular bearing surface wherein at least one predetermined portion of the bearing surface is provided with cross-linked polymer bonds.

A mold for molding a reinforced preform having at least two apertures therein includes first and second mold halves arranged with their respective first and second molding surfaces facing each other. A first emitter is disposed in the first mold half and is configured to emit light therefrom. A first receiver is disposed in the second mold half and is configured to receive light from the first emitter and produce a first signal indicative of the light received from the first emitter. A second emitter is disposed in one of the first and second mold halves and is configured to emit light therefrom. A second receiver is disposed in the other of the first and second mold halves and is configured to receive light from the second emitter and produce a second signal indicative of the light received from the second emitter.

To provide an device capable of producing a resin block of any rosin material. Resin pellets (7) supplied to a resin block forming space (150) are heated and melted by a heater unit (300) and the melted resin pellets (7) are cooled and solidified to form a resin layer. Since a lifting mechanism (230) of a lifting unit (200) lowers a bottom surface plate (215) whenever forming each of the resin layers, the resin layers formed by the resin block forming space (150) are sequentially laminated to form a large resin block.

A method of producing a sealed structure, the method including: preparing a substrate and a curable resin composition in a liquid form; and sealing the substrate with the curable resin composition, to form a sealed body including the substrate and a cured product of the curable resin composition. The sealing step includes: printing the curable resin composition onto the substrate, to cover the substrate with a first coating film of the curable resin composition; and compression-molding the first coating film and the substrate together using a mold, with a pressing surface of the mold abut against the first coating film, to convert the first coating film into a second coating film. A ratio of a projected area S1 of the first coating film onto the substrate to a projected area S2 of the second coating film onto the substrate: S1/S2 is 0.9 or more.

A waveguide includes an input area, a multi-layered substrate, and an output area. The multi-layered substrate includes a plurality of layers of at least a substrate and at least one partially reflective layers. The input area in-couples light in a first band into the waveguide. The one or more partially reflective layers are partially reflective to light in the first band. Each of the one or more partially reflective layers are located between respective layers of the plurality of layers of the substrate. The output area out-couples light from the waveguide. The pupil replication density of the out-coupled light is based in part on a number of the one or more partially reflective layers and respective locations of the one or more partially reflective layers in the waveguide.

A method for fabricating a stiffened panel. Layers of composite material are placed on a surface of an inner-mold-line tool having protrusions that extend from the surface of the inner-mold-line tool. The layers of composite material laid-up on the surface of the inner-mold-line tool are compacted to form compacted layers of composite material. The compacted layers of composite material are cured to form an inner-mold-line layer having corresponding protrusions. The inner-mold-line layer is joined to an outer-mold-line layer.

The invention proposes a method for manufacturing a grille for a cascade type thrust reverser, of a jet engine, said method including the following steps: a) manufacturing a first component comprising continuous or long fibres, pre-impregnated by a thermoplastic or thermosetting resin; b) manufacturing, subsequently or together with step a), a series of second components each including discontinuous fibres, pre-impregnated by a thermoplastic or thermosetting resin, step b) being carried out such that the second components are, on the one hand, arranged transversally with respect to a longitudinal direction of the first component on at least one side of the first component and, on the other hand, spaced from one another according to this longitudinal direction, so as to form a comb-shaped structure, wherein the second components are consolidated to the first component.

A system for fabricating composite parts efficiently. Pre-impregnated (prepreg) composite material is drawn as a sheet from a roll and fed by advancement rollers into a stamping and molding station in which a piece of the prepreg material is cut, on a mold, from the sheet. Pressure is applied to cause the prepreg material to conform to a surface of the mold, and the prepreg is cured with ultraviolet light. Additional layers of prepreg may be cut and cured on any layers that have already been cured on the mold. The complete part may be removed from the mold with ejector pins. Scrap prepreg may be recycled in a recycling station that separates reinforcing fiber from uncured resin.
