摘　　要：在氧化处理后的碳纤维 (CF)表面涂敷不同的偶联剂 ,石英粉用KH -5 5 0和脱模剂处理 ,然后在双辊混炼机上与双马来酰亚胺 (BMI)树脂熔融混炼 ,采用模压工艺制备CF/SiO2 /BMI复合材料试样 ,对其弯曲强度和吸水率进行了测试。并且用电子光谱化学分析 (ESCA)分析了氧化前后碳纤维表面的成分和官能团 ,讨论了碳纤维表面处理对复合材料弯曲强度的影响。结果表明 。Carbon fiber was desized in air at 600 ℃,and then was treated by coupling agents.SiO 2 powder was treated by KH-550 and demolding agent.BMI,the treated carbon fiber and SiO 2 were mixed at 90～100 ℃ and then molded into composite sample.Surfaces of carbon fiber were analyzed by ESCA,the bending strength and water absorption of the composites were tested.
