纤维复合材料广泛用于空间应用，如太阳能电池阵列、天线、光学平台和低温储罐的支撑。最新成功发射的卫星之一是红外空间天文台（ISO）。低温储罐支撑结构的导热性限制了ISO的使用寿命。最近的研究表明，优化负载适应支撑结构可以从根本上降低热导率，从而增加这类卫星的寿命。超高模量碳复合材料可以降低光学平台和天线的水分变形。新的测试样品和程序允许改进的选择复合材料的专门应用。本文介绍了最近发射的卫星的复合结构。在材料评估方法，结构分析和设计的改进，为未来的发展展示。1998爱思唯尔科学有限公司版权所有。
Fibre composites are widely used for space applications, such as solar arrays, antennas, optical platforms and supports for cryogenic tanks. One of the latest successfully launched satellites is the Infrared Space Observatory (ISO). The lifetime of ISO is mainly limited due to the thermal conductivity of the cryogenic tank support structure. Recent efforts show that optimized load adapted support structures can essentially decrease the thermal conductivity and thus increase the lifetime of such satellites. Ultra high modulus carbon composites can decrease the moisture induced deformations of optical platforms and antennas. New test specimens and procedures allow an improved selection of composites for specialized applications. In this paper composite structures of recently launched satellites are described. Improvements in material evaluation methods, structural analysis and design for future developments are demonstrated. (C) 1998 Elsevier Science Ltd. All rights reserved.
