中文摘要：

将不同含量碱处理的剑麻纤维（SF）与酚醛树脂（PF）粉末、填料等在塑炼机上熔融混炼，通过模压成型工艺制备SF／PF复合材料，研究了SF含量对SF／PF复合材料力学性能、动态力学性能、摩擦磨损性能的影响，并借助SEM观察SF／PF复合材料磨损面的微观形貌。结果表明，SF含量（质量分数，下同）为15％时，SF／PF复合材料的冲击强度、弯曲强度分别为5．58kJ／m2和67．69MPa，玻璃化转变温度（tg）达到204℃，与未加SF复合材料的相比tg提高13℃；SF含量为10％时，SF／PF复合材料的磨损体积为4．6×10^-4cm3。SEM观察表明，SF含量10％时，SF与PF间的界面粘结性良好。

英文摘要：

Sisal fiber （SF） was pretreated by alkali firstly. SF/phenol formaldehyde （PF） composites were prepared through compression molding. Effects of different mass fraction of SF on mechanical properties, dynamic mechanical behavior and wear resistance of SF/ PF composites were investigated. Worn morphologies of the composites were observed by SEM. The results show that the impact strength, bending strength come up to 5.58 kJ/m2 and 67.69 MPa when the mass fraction of SF is 15%, and the glass transition temperature of the composite is improved by 13℃. When SF is 10% , the composite has low wear volume 4.6 × 10^-4 cm3. SEM of SF/PF bonding clearly demonstrates better when SF content is 10%.
