摘　　要：分别采用偶联剂、氧化剂和胶粘剂作为表面处理剂,以非石棉纤维增强橡胶基密封复合材料(NAFC)高温时效处理后的残余横向抗拉强度为指标,研究了不同的纤维表面方法对增强纤维与橡胶的结合度以及对NAFC材料高温性能的影响。试验结果和试样拉伸断面扫描电镜照片分析表明,采用RFL乳液作为芳纶-预氧化丝混杂纤维增强NAFC材料的纤维表面处理剂,对提高材料的高温性能具有较好的效果。By using coupling agent,oxidizing agent and adhesion agent as surface treatment agent respectively, some aramid and pre-oxidized hybrid fiber reinforced sealing composite materials （NAFC） were developed. The effect of different surface treatment method both on heat resistance of NAFC material and on the interface combining power between reinforced fiber and rubber was investigated ,according to the transverse tensile strength of the NAFC material after aging treatment at 250℃. The experimental and the SEM analysis results indicate that the RFL adhesion agent is the best surface treatment agent to the aramid and pre-oxidized hybrid fiber to improve the heat resistance of the NAFC material.
