| 摘 要： | 将硼酚醛树脂(BPR)与普通酚醛树脂(PF)熔融共混,再加入经过碱处理的剑麻纤维(SF),通过模压成型工艺制备BPR/SF/PF复合材料。利用定速式摩擦试验机和电子万能试验机研究了BPR含量对复合材料摩擦磨损性能及力学性能的影响,采用扫描电镜观察了复合材料磨损表面的形貌。结果表明:在BPR/PF=50/100时,与普通PF/SF复合材料相比,BPR/SF/PF复合材料在300℃下的磨损率降低了42%,冲击强度提高了14%,弯曲强度和弯曲模量分别提高了25%和36%;复合材料磨损面形貌显示,加入BPR后,复合材料由疲劳磨损转变为磨粒磨损。

| Abstract: | Boron phenolic resin (BPR) and ordinary phenolic resin (PF) were melt blended, and the sisal fiber treated by alkali was added to prepare BPR/SF/PF composite by compression molding technology. The friction and wear properties and mechanical properties of the composite were investigated by constant speed friction tester and electronic universal tester. The abrasion surface of the composite was observed by scanning electron microscope. The results show that compared with PF/SF composite, when BPR/PF=50/100, the wear rate of BPR/SF/PF composite at 300 ℃ decreases by 42%, the impact strength, flexural strength and flexural modulus increase by 14%, 25% and 36% respectively; SEM photos indicate that the wear mechanism of the composite changes from fatigue wear to abrasive wear after the addition of BPR. |
