摘　　要：本文研究了SiO2 和纤维增强剂对于聚氨酯硬泡塑料冲击性能的增强效应。试验结果表明 ,加入SiO2 并不能增强聚氨酯硬泡塑料冲击性能。然而以 2 .5 %KH5 5 0偶联剂四氢呋喃溶液处理的玻璃纤维作为增强剂 。The effect of the reinforcement of SiO 2 particles and fiber on Polyurethane foam plastics is studied. The experimental result shows that the impact properties of PU foam plastics with no intensifier are increased with density. However, when the density is fixed, the impact strength is decreased with the adding of SiO 2 particles. It means that the rigid particles cannot increase the impact strength of the PU foam plastics. While the glass fiber treated with 2 5% concentration of coupling agent KH550 is used as intensifier, the impact strength of PU foam plastics can be improved obviously.
