空心光纤网络埋入复合材料中性能影响的研究

The Performance Research on Hollow Center Optical Fiber Network Embedded in Composite Materials

空心光纤网络可用来进行复合材料力学性能的监测 ,同时又可对材料的损伤进行自修复。空心光纤网络与复合材料性能的影响主要有三方面 :1 )复合材料对空心光纤的影响 ;2 )空心光纤对复合材料的影响 ;3 )空心光纤与复合材料力学性能的匹配。本文测试了三种规格的空心光纤埋入复合材料中受到的影响 ,依据国家有关的复合材料测试标准 ,对树脂基复合材料埋与不埋大直径空心光纤进行了对比实验 ,并论证了光纤与材料力学性能匹配点存在的必然性。从而为空心光纤网络用于复合材料的自诊断与自修复提供了研究的依据。

Hollow center optical fiber network can be used to inspect the mechanics performance, and embedded to repair the damage and crack in composite materials. There are three main factors: 1) the influence of composite materials; 2) the influence of hollow center optical fiber; 3) the mechanical performance matching each other. Three hollow center optical fibers are used to test the influence of composite materials. The test of composite materials embedded optical fiber or not is done according to the Chinese standard. Finally, the mechanical performance matching is demonstrated to provide a proof for self diagnose and self repair with hollow center optical fiber network in composite materials.
