    • A method of fabricating complex hollow composite structures from laminates of fiber reinforced synthetic resins. The structures are fully monocoque tubes with no seams. The tubes are manufactured by wrapping a hollow semi-rigid inner mandrel made of thermoplastic material such as polystyrene or ABS (acrylonitrile-butadiene-styrene co-polymer) with layers of composite sheets. The sheets are made from high-strength fibers impregnated with thermosetting or thermoplastic resins. The laminated mandrel is placed in a mold, heated and inflated to a predetermined pressure. The pressure can range from 20-200 psig and even higher, while the curing temperature can range from 200.degree.-600.degree. F. The pressure generated by the expanding core produces a highly consolidated composite structure that has fewer voids, a more uniform thickness, and an increased fiber content compared to hollow composites made by other fabrication methods.
    • 一种从纤维增强合成树脂层压板制造复杂中空复合结构的方法。 结构是完全没有接缝的单体管。 这些管通过包裹由诸如聚苯乙烯或ABS(丙烯腈 - 丁二烯 - 苯乙烯共聚物)的热塑性材料制成的空心半刚性内心轴与复合片材层一起制成。 片材由浸渍有热固性或热塑性树脂的高强度纤维制成。 将层压心轴放置在模具中,加热并膨胀至预定压力。 压力可以在20-200psig甚至更高的范围内,而固化温度可以在200-600°F范围内。膨胀芯产生的压力产生高度固结的复合结构,其具有较少的空隙,更均匀的厚度, 并且与通过其它制造方法制成的中空复合材料相比,纤维含量增加。

    • A carbon-carbon mirror for high thermal input space applications is comprised of a plurality of thermally conductive, metallic layers formed as a laminate structure atop a carbon-carbon substrate. Within the laminate structure, a first thin adhesion layer of chromium is formed directly on the surface of a carbon-carbon substrate. Atop the adhesion layer, a plating base layer of gold or copper is deposited, followed by a thick working/smnoothing layer of nickel, which serves as the optically reflective surface of the mirror. The nickel layer is polished to a precision flatness or smoothness. Because the underlying gold and chromium layers possess high thermal conductivity, they enhance the transmission of heat from the cladding layer to the underlying carbon-carbon substrate, thereby preventing the laminate from absorbing heat, which would lead to delamination of the structure. In order to minimize thermally induced distortion of the mirror structure, the metal laminate build-up is preferably formed on opposite sides of the carbon-carbon substrate, thereby affording a thermal balancing of the substrate. However, the nickel layer on the non-reflective side of the mirror is not polished.
    • 用于高热输入空间应用的碳 - 碳反射镜由多个导热的金属层组成,其形成为碳 - 碳基板顶部的层压结构。 在层压结构内,直接在碳 - 碳基板的表面上形成第一薄铬层。 在粘合层的顶部,沉积金或铜的电镀底层,然后沉积作为反射镜的光学反射表面的厚的加工/疏松层的镍。 将镍层抛光至精确的平坦度或平滑度。 因为底层的金和铬层具有高导热性,所以它们增强了从包覆层到下面的碳 - 碳基底的热传递,从而防止层压体吸收热量,这将导致结构的分层。 为了最小化反射镜结构的热诱导畸变,金属叠层叠层优选形成在碳 - 碳基板的相对侧上,从而提供基板的热平衡。 然而,反射镜的非反射侧的镍层未被抛光。
