1.前言炭纤维的工业化生产,是通过将PAN.石油沥青或煤焦油沥青原料进行热处理制得。其热处理过程可分为两步: 〈a〉在300-500℃下前驱体纤维的表面予氧化处理; 〈b〉在1000-2500℃下纤维的热解炭化。复合材料关键性质是层间剪切强度,它主要取决于纤维与高聚物树脂两者间的粘合程度。所以,为了提高炭纤维与树脂基体间
1. Preface The industrial production of carbon fiber is made by heat treatment of PAN. Petroleum pitch or coal tar pitch material. The heat treatment process can be divided into two steps: Pre-oxidation of precursor fibers at 300-500 ° C; Pyrolysis charring at 1000-2500 ° C. The key property of composites is the interlaminar shear strength, which depends mainly on the degree of adhesion between the fiber and the polymer resin. Therefore, in order to improve the carbon fiber and resin matrix
