In this study, PAN-based carbon fiber was selected to undertaking bulk modification through ultralow temperature also called cryogenic treatment. The interfacial properties of un-treated and cryo-treated carbon fiber were studied in a comparative manner. The interfacial shear strength (IFSS) of modified carbon fibers with epoxy resin was characterized by means of the micro-bond test and the result showed an increase of 29.5%. The atomic force microscope (AFM) showed rougher surface after cryogenic treatment which in agreement with the result of IFSS. The structure of carbon fiber was characterized by X-ray Diffraction (XRD), which indicated some physical changes in fiber structure.
文章採用深冷處理也稱為超低溫處理對聚丙烯腈基碳纖維進行介面改性。將處理前和處理後碳纖維的介面性能進行對比研究。通過對碳纖維與環氧樹脂進行微滴實驗表明,深冷處理後碳纖維的介面剪切強度(IFSS)提高了29.5%。原子力顯微鏡(AFM)顯示處理後纖維表面變粗糙,這與IFSS的結果一致。採用和X射線衍射(XRD)對碳纖維的結構進行表徵,結果表明處理後纖維結構存在一些物理變化。
