碳纤维增强复合材料(CFRP)在大型承载结构上的应用是一项非常新的技术。阿里安双星发射外支架(SPELDA)结构被设计成能在150℃的高温下承受高载荷的恶劣环境中满足严格的质量、刚度和强度要求。这种对采用CFRP制作的结构进行具体设计的技术,与采用常规材料的情况相比,还停留在开始阶段。材料的破坏机理还不十分清楚,对这种材料的性能,至今还没有得到广泛承认的分析评定方法,或者确实的试验测定方法。在空间工业的商业环境中,即在计划时间相对较短的情况下,这种发射支架的研制有其特殊的工程方法。本文叙述了SPELDA結构的设计和改进方法。
The application of carbon fiber reinforced plastics (CFRP) to large load-bearing structures is a very new technology. The Arian BELT SPELDA structure is designed to meet stringent quality, stiffness and strength requirements in the harsh environment of high loads at 150 ° C. This technique of designing concretely using CFRP-made structures is still in its infancy as compared with the case of using conventional materials. The failure mechanism of the material is not yet clear enough. To date, the performance of this material has not been widely recognized as an analytical method or a validated test method. In the space industry’s commercial environment, where the planning time is relatively short, the development of such launching stents has its own engineering approach. This article describes the SPELDA structure design and improvement methods.
