作者报告了当添加高结晶多壁碳纳米管时，传统碳纤维/酚醛树脂复合体系的导热性显著增强。他们证明，7 wt %的碳纳米管均匀地分散在酚醛树脂中，作为相邻碳纤维之间的有效热桥，并导致导热系数的增强（例如，从250到393 W/m K）。这些结果表明，高结晶碳纳米管可以作为一种多功能填料，同时提高碳纤维/酚醛树脂复合材料的力学性能和热性能。(c) 2007年美国物理学会。
The authors report a significant enhancement in the thermal conductivity of a conventional carbon fiber/phenolic resin composite system when adding highly crystalline multiwalled carbon nanotubes. They demonstrate that 7 wt % of carbon nanotubes dispersed homogeneously in a phenolic resin acted as an effective thermal bridge between adjacent carbon fibers and resulted in an enhancement of the thermal conductivity (e.g., from 250 to 393 W/m K). These results indicate that highly crystalline carbon nanotubes can be used as a multifunctional filler to enhance simultaneously the mechanical and thermal properties of the carbon fiber/phenolic resin composites.
