摘　　要：对棕榈纤维进行脱胶处理,测试分析了处理前后的纤维化学组分、表面形态、力学性能和红外光谱。分别以未处理和处理后的棕片为增强相,以沙林热塑性树脂为基体,通过热压制备复合材料,探讨了热压温度对复合材料外观形貌以及拉伸、弯曲性能的影响。结果表明:脱胶处理后棕榈纤维表面变得相对光滑,大部分胶质、木质素被去除,纤维素含量提高,力学性能增强;棕片/沙林复合材料的最佳成型工艺为热压温度100℃、压力25 MPa、时间1 h,其拉伸强度为(32.31±8.05)MPa,拉伸模量为(469.97±86.96)MPa。The chemical composition,surface morphology,mechanical properties and infrared spectra of the palm fibres are analyzed before and after the degumming process.And the composites are prepared by hot pressing using untreated and treated palm chips as the reinforcing phase and surlyn thermoplastic resin as the matrix,respectively,and the effects of hot pressing temperature on the forming appearance,tensile and bending properties of the composites are investigated.The results show that the surface of palm fibers become relatively smooth after degumming,most of the gum and lignin are removed,the cellulose content is increased and the mechanical properties are enhanced;the optimum moulding process for the palm chips/surlyn composite is hot pressing at 100 ℃,25 MPa and 1 h.The tensile strength is(32.31±8.05)MPa and the tensile modulus is(469.97±86.96)MPa.
