摘要
本文综合介绍了近年来国外迅速发展的具有光纤神经系统的新颖复合材料结构的研究成果及发展趋势。提出了埋设于复合材料内部的光纤系统将成为未来飞行器结构的“神经网络系统”而使结构成为“智能结构”等新概念。文章较详细地阐述了这种新颖结构在制造和使用过程中在应变、变形、固化、损伤、疲劳等检测方面的具体应用及发展趋势。
The achievements on smart composite structures with embedded optical fibers which are going rapidly ahead in developed countries are described in this paper. The optical fiber system embedded in composite materials will become a 'Neutral Network System' of the future aircraft structures,leading to new concepts of the 'Intelligent Structures'. This paper puts emphasis on measurement and monitoring of strain,deformation,curing,damage and fatigue,which are quite suitable for smart composite structures in fabrication,installation and in service. The future prospect about this new field is mentioned in brief.
