Research On The Capabilities Of New-Style LCOF

Liquid Core of Optic Fiber (LCOF) is a new-style optic fiber, it is adopted transparent liquid as its core. Different liquid systems can be used in different wavebands. So the choice of liquid core is greatly abroad. In recently, there are many researches reported, but these researches mostly focus on its optic spectrum and easy application.In the thesis, the research of LCOF is put forward, and the LCOF is used to inspect the state of the composite materials. In this paper, the LCOF is developed by self. The mainly researches of the LCOF are following(1) Experiment on capability of bear the weight of the LCOF, and compared with usually optic fiber.(2) Research on the solidification of liquid core to seek after the rule of the changing light intensity.(3) Study on the damage and repair of the LCOF.(4) Investigation of the capabilities of sensitivity of temperature and microbend.(5) Research on the compatibility of the LCOF between composite materials.All of the researches are shown that, the LCOF has good capabilities of temperature, bearing and microbend, and it is can be belt in composite materials. When the LCOF is damaged, it can be repaired by its liquid core which is radiated by special illumination, and the repaired LCOF can be still used to inspect the structure of composite materials. So the LCOF has great application value.
