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
