摘要:
Panneau léger et intégral de cellules solaires contenant une pluralité de cellules solaires interconnectées liées à un film de polyimide renforcé par des fibres fabriqué à partir d'un précurseur contenant des isoimides. Les cellules solaires peuvent être placées sur le film de polyimide renforcé lorsque le film est encore partiellement durci, et les cellules restent collées au film lorsque le durcissement est achevé. Un film polymère transparent, tel qu'un polyimide, peut être utilisé comme moyen de protection des surfaces antérieures des cellules.
摘要:
An embodiment of the present invention provides a method for manufacturing a composite preform from tape material, including feeding a tape section into a tape section guide that suspends the tape across a tooling surface, moving at least one of the tape section guide and the tooling surface relative to each other to position the tape section at a desired location and orientation relative to the tooling surface, moving the tape section toward a pre-existing tape section disposed on the tooling surface, and tacking the tape section to the pre-existing tape section. A corresponding apparatus for manufacturing composite preforms is also disclosed.
摘要:
The present invention relates to polyethylene material that has a plurality of unidirectionally oriented polyethylene monolayers cross-plied and compressed at an angle to one another, each polyethylene monolayer composed of ultra high molecular weight polyethylene and essentially devoid of resins. The present invention further relates to ballistic resistant articles that include or incorporate the inventive polyethylene material and to methods of preparing the material and articles incorporating same.

A method of manufacturing an implantable pump includes providing an upper layer comprising a dome structure for housing a drug chamber and a cannula in fluid communication with the drug chamber. A middle deflection layer is provided adjacent the drug chamber. A bottom layer is provided comprising either electrolysis electrodes or a permeable membrane. The upper layer and middle deflection layer are thermally bonded to form the drug chamber of the pump. The bottom layer is bonded to the drug chamber to form the pump.

A method of manufacturing a core stiffened structure includes orienting the plurality of core wafers (2401) in a non-uniform pattern onto a first face sheet (2805), the non-uniform pattern producing non-uniform spacing (2809) between adjacent core wafers; assembling a second face sheet (2803) onto the plurality of wafers (2401); and curing an adhesive to create a bond between the plurality of wafers (2401), the first face sheet (2805), and the second face sheet (2803).
摘要:
An apparatus comprising: a piezo-electric material structure having a first side and a second side, the piezoelectric material structure comprising a plurality of fibers (26) in juxtaposition, each fiber further having a first side and a second side, the first and second sides of the fibers defining the first and second sides, respectively, of the piezo-electric material structure; a first film (28) bonded to the first side of the structure, the first film having a first side and a second side, the first film further comprising first and second conductive patterns (30,32), each conductive pattern being in electrical contact with the piezo-electric material structure, the first conductive pattern being electrically isolated from the second conductive pattern, the first and second conductive patterns each having a plurality of electrodes (36,40) which form a pattern of interdigitated electrodes; and a second film (42) bonded to the second side of the structure, the second film preferably having a construction similar to the first film.
