摘要(Abstract)：

分别以杨木高得率浆(HYP)、杨木化学浆(CP)、废纸板浆(WPP)为原料,研究热压初始水分含量(IMC)对重载纤维模塑材料性能的影响。依照Herzberg染色法和造纸原料化学分析的标准比较了纤维原料纤维种类和化学成分的异同,采用XPS、XRD和SEM表征手段系统比较了IMC对重载纤维模塑材料的化学组分、聚集态结构以及微观形貌的影响,同时考察了IMC对重载纤维模塑材料物理力学性能的影响。实验结果表明,零压干燥时,IMC增加导致WPP模塑材料密度与力学强度降低。在热压条件下,IMC的提高,促进胶黏性聚合物的生成,有助于改善HYP和CP模塑材料的结晶指数,利于纤维细胞腔压实和纤维间的紧密交织;IMC的提高,能够显著提高HYP、CP和WPP纤维模塑材料的密度和力学强度,IMC由10%增加到60%时,HYP、CP和WPP模塑材料的密度提高18.6%、23.8%和8.0%,拉伸强度提高119.74%、173.2%和168.3%,弯曲强度提高134.9%、140.2%和125.0%。
