黄麻纤维增强不饱和聚酯树脂初步研究

以油酸为偶联剂,将氢氧化钠-油酸处理后的黄麻纤维布作为填充材料制备了不饱和聚酯复合材料,并对氢氧化钠处理黄麻纤维的适宜浓度、复合材料的拉伸强度、冲击强度、吸水率进行了研究测试。结果表明:氢氧化钠的适宜浓度为20%,黄麻纤维增强不饱和聚酯树脂的冲击强度及拉伸强度最大值分别为12.75 kJ/m2和33.05 MPa,复合材料的最大吸水率为4.07%。经油酸处理的黄麻纤维可有效提高不饱和聚酯复合材料的性能。

Preliminary research on jute fiber reinforcing unsaturated polyester resin

The unsaturated polyester composites were prepared using sodium hydroxide-oleic acid treated jute fiber cloth as the filler material and the oleic acid was using as the coupling agent.The appropriate concentration of sodium hydroxide treated the the jute fibers,tensile strength,impact strength and water absorption of the composites were investigated and tested.The results showed that the appropriate concentration of sodium hydroxide was 20%.The maximum impact strength and tensile strength of jute fiber reinforced unsaturated polyester resin were 12.75 kJ/m2 and 33.05 MPa,respetively.The maximum water absorption of the composite was 4.07 %.Oleic acid-treated jute fiber could effectively improve the performance of the unsaturated polyester composites.
