采用动态力学分析(dynamic mechanical analysis)方法研究了纳米羟基磷灰石(nano-hydroxyapatite, n-HA)增强聚酰胺66(polyamide 66, PA66)生物复合材料的动态力学性能.结果表明,复合材料中纳米羟基磷灰石组分的含量、生理盐水和振动频率对n-HA/PA66复合材料的动态力学性能和玻璃化转变过程都有一定程度的影响.随着纳米羟基磷灰石含量的增加,其复合材料的力学损耗峰温度移向高温区,峰值降低;复合材料吸水后其储能模量和损耗模量都有所降低,且玻璃化温度向低温区移动;振动频率对复合材料的动态力学性能也有一定的影响, 随着振动频率的增加,复合材料的储能模量也有所提高.
