Epoxy-sized textile-grade polyacrylonitrile (PAN) carbon fiber (TCF) with 450 K filaments (CFTF, ORNL) was reinforced in the polycarbonate (PC) matrix using a compression molding technique. The epoxy sizing effect on the surface, thermal, and mechanical properties of TCF–PC was investigated. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy results of the TCF–PC composite show the absence of an oxirane group (epoxy-sized TCF), which suggests a covalent bond formation between the oxirane ring and carbonyl groups from TCF and PC. Dynamic mechanical analysis results confirm a strong immobilized interface (b > 1) present between TCF and PC. The tensile, flexure, compression, and interlaminar shear strength of TCF–PC composites were 323 ± 53, 371 ± 31, 397 ± 87, and 36 ± 3 MPa, correspondingly. The fracture analysis through scanning electron microscopy shows good wettability between TCF and the PC matrix which validates the results obtained from surface and thermal characterization.

纺织级碳纤维增强聚碳酸酯复合材料：环氧施胶的影响
使用压缩成型技术将具有450 K长丝（CFTF，ORNL）的环氧树脂级纺织级聚丙烯腈（PAN）碳纤维（TCF）增强到聚碳酸酯（PC）基体中。研究了环氧胶对TCF–PC的表面，热和机械性能的影响。TCF-PC复合材料的X射线光电子能谱和傅里叶变换红外光谱结果表明，不存在环氧乙烷基（环氧大小的TCF），这表明环氧乙烷环与TCF和PC的羰基之间形成共价键。动态力学分析结果证实了牢固的固定界面（b> 1）存在于TCF和PC之间。TCF-PC复合材料的拉伸，弯曲，压缩和层间剪切强度分别为323±53、371±31、397±87和36±3 MPa。通过扫描电子显微镜进行的断裂分析表明，TCF和PC基质之间具有良好的润湿性，这验证了从表面和热表征获得的结果。
