短切碳纤维增强氟橡胶复合材料的制备及表征
采用短切碳纤维（CF）增强氟橡胶（FR）,制备了短切CF/FR复合材料,考察了短切CF的用量、偶联剂的种类以及硫化条件对复合材料力学性能的影响,并采用傅里叶变换红外光谱和扫描电子显微镜对复合材料的微观结构和形貌进行了表征。结果表明,短切CF的用量为12份时,制备的短切CF/FR复合材料的综合性能最佳;用硅烷偶联剂KH 550对短切CF进行表面处理,制备的短切CF/FR复合材料的力学性能优于以Si 69处理的材料;制备短切CF/FR复合材料的最佳硫化条件为10 MPa×170℃×15 min;短切CF与FR之间存在化学键的结合,提高了短切CF与FR的相容性;用偶联剂KH 550处理短切CF,短切...

The effects of the amount of CF,the variety of silane coupling agent and the curing conditions on mechanical properties of the composites were investigated,and the microstructure and micromorphology were analyzed by Fourier transform infrared spectroscopy and scanning electron microscope. The results showed that the amount of CF was 12 phr and the curing conditions were 10 MPa × 170 ℃ × 15 min,the mechanical properties of CF / fluorine rubber composites were the best. The mechanical properties of the composites,in which CF surface was treated with silane coupling agent KH 550,were better than those with Si 69. The compatibility of chopped CF and fluorine rubber were enhanced by chemical bonding of chopped CF and fluorine rubber. Treated with KH 550,CF had the better compatibility with fluorine rubber th |
