本研究旨在通过导电方法揭示CF/PPS层状复合材料熔融氧化现象的机理。使用的材料是单向CF/PPS和编织CF/PPS层压板。研究了外加电压、导电时间和纤维增强结构对CFRTP复合材料熔化行为的影响。通过显微镜观察和图像分析评价熔融状态。实验结果表明，CFRTP层压板的电阻率和增强结构对熔化和氧化行为有影响。两种CFRTP层板的熔化面积都随着外加电压和导通时间的增加而增加。结果表明，为了防止熔融区的边缘效应和不均匀的轮廓形状，需要在熔融界面处插入PPS薄膜。研究还证实了编织CF/PPS层合板在低电压下可以熔化。
This study aims to reveal the mechanism of melting and oxidation phenomenon of CF/PPS laminated composites by electrically-conducting. The materials used are unidirectional CF/PPS and woven CF/PPS laminates. The effects of applied voltage, conducting time and fiber reinforcing configuration on melting behavior of CFRTP composites were investigated. The melting state was evaluated by microscopic observation and its image analysis. The experimental results revealed that the melting and oxidation behavior were influenced by reinforcing configuration and electric resistivity of CFRTP laminates. The melting area of both CFRTP laminates tends to increase with increasing the applied voltage and conducting time. It was found that the insertion of PPS films in melting interface was required in order to prevent the edge effect and non-uniform profile shapes of the melting area. It was also confirmed that woven CF/PPS laminates could be melted at low applied voltage.
