摘　　要：　研究纤维与颗粒混杂增强聚氨酯复合硬泡塑料的物理及力学性能,着重分析增强剂SiO2颗粒和玻璃纤维含量以及纤维长度对其性能的影响。结果表明,SiO2含量为20wt%,玻璃纤维含量为7.8wt%时,试样的拉伸强度达到最佳值。此外,还比较了玻璃纤维、尼龙66纤维和PAN基碳纤维的增强效果。结果表明,3wt%～5wt%含量碳纤维增强的聚氨酯复合硬泡塑料拉伸强度最佳。The physical and mechanical properties of hybrid reinforced rigid polyurethane (PU) composite foam were investigated with reinforcing agents of SiO2 particle and fibre. The effect of the content of SiO2 and fibre on the properties of the PU composite foam was emphatically analysed, and the effect of the length of fibre on its properties was also studied. The experiment results show that the tensile strength of the PU composite foam is optimal when the content of SiO2 is 20 wt% and the content of glass fibre is 7.8 wt%. The reinforcing effects of glass fibre, Nylon66 fibre and PAN-based carbon fibre were compared. The result shows that the tensile strength of the PU composite foam reinforced with 3 wt%-5 wt% carbon fibre is optimal.
