摘要：

Aspen chemithermomechanical pulp fiber-reinforced unsaturated polyester (UPE) composites were fabricated using premade paper handsheets. The effects of handsheet wet-pressing pressure, grammage, and subsequent fabrication methods on the composite properties were evaluated. The composites obtained using the optimum process parameters had tensile moduli and tensile strengths comparable with those of traditional glass fiber-reinforced UPE composites. The pressed composites had very consistent tensile moduli that were well fitted by the HalpinTsai and TsaiPagano models. The classical Kelly-Tyson and Bowyer-Bader models significantly underestimated the composite tensile strengths and the potential reasons for this discrepancy are discussed. POLYM. COMPOS., 2012.
