摘要: 本文以自制酚醛树脂发泡制备的酚醛泡沫为基体,Nomex纸蜂窝为增强体,采用特定的发泡制备工艺制得了Nomex纸蜂窝增强酚醛泡沫。通过对该材料微观形貌、力学性能和热性能的表征,初步探讨了材料基体和界面效应对其力学性能和隔热性能的影响。研究结果发现,填充了酚醛泡沫后,Nomex纸蜂窝增强酚醛泡沫的力学性能显著提高,导热系数显著降低。分析认为,良好的强结合界面保障了酚醛泡沫对Nomex纸蜂窝增强酚醛泡沫力学性能和隔热性能的贡献,该材料是一种综合性能较好的隔热、阻燃材料。

Abstract: Nomex honeycomb reinforced phenolic foam was produced through special foaming craft,from the matrix phenolic foam and the reinforcement Nomex honeycomb. The effect of matrix and that of the interface on mechanic and thermal conductivity were analyzed through the performance characterization of micro-structure, machanics and thermal conductivity. It was obviously found that the mechanics was enhanced and thermal conductivity was reduced after phenolic foam was filled in Nomex honeycomb. It was concluded that the form of the hard interface made the phenolic foam benefited to the increase of machanics and the decrease of thermal conductivity and it was still a good fire retarding and heat insulating material.

Key words: phenolic foam, Nomex honeycomb, mechanics, thermal insulation
