摘要/Abstract

摘要： 利用FBG传感器对采用真空导入模塑工艺制作的CF/GF(Carbon Fiber/Glass Fiber)混杂复合材料在固化成型过程中以及成型后的界面性能进行了检测,此外,为了对比研究混杂复合材料的性能,还检测了CF/CF层和GF/GF层在成型和成型后的应变变化。结果显示:GF/GF、GF/CF和CF/CF复合材料的应变与温度之间存在良好的线性关系,且热膨胀系数的大小顺序为GF/GF层>GF/CF层>CF/CF层;FBG传感器监测CF/GF混杂复合材料热膨胀系数的转折温度与基体树脂的T_g值(79.09 ℃)相吻合;CF/GF混杂复合材料在20~120 ℃范围内升温、降温过程中未发生界面破坏。

Abstract: In this paper, the FBG sensor was used to study the interfacial properties of CF/GF hybrid composites during and after the curing process. In order to investigate the properties of hybrid composites, the strain changes in CF/CF layer and GF/GF layer are also monitored. The results show that when no external force, good linear relationship between strain and temperature existed in GF/FG, GF/CF and CF/CF layers, and the order of thermal expansion coefficient is: GF/GF layer>GF/CF layer>CF/CF layer. FBG sensor for the monitoring of CF/GF hybrid composite heat swelling values for the coefficient of the transition temperature and the matrix resin (79.09 ℃) coincide. CF/GF hybrid composites in 20~120 ℃ heating and cooling process do not show destruction of the interface.

Key words: CF/GF hybrid fiber reinforced plastic, fiber bragg grating sensor, real time monitoring, thermal expansion property
