Investigation on Status and Prospective Application of Composite Multifunctional Structures Technology

Spacecraft reduces flight system mass is one of the stratagem target of developing spaceflight technology in 21 century.Developing Multifunctional Structure(MFS) is a vital technical measure of decreasing the mass and procedure cost.MFS is a new system for spacecraft design that chassis,cables and connectors were replaced by flexible-circuit.Multi-chip module replaced Printing Wiring Board and other aviation electronics.Concurrent engineering will be essential to integrate the electronic,structure,and thermal design into the walls of the spacecraft.The main objective of this article is to provide a comprehensive overview of the foreign MFS models of advanced composites and presents the concept,basic compose of MFS and the characteristic and applicable field of variety MFS.Finally some opinions of the authors about the future development and the prospective application are presented.
