Abstract

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.

摘要

文章採用深冷處理也稱為超低溫處理對聚丙烯?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。
