Beschreibung
Zusammenfassung:	The invention discloses a cured carbon fiber felt and a preparation method thereof. The method is mainly based on a foaming principle to realize uniform distribution of carbon fibers in the cured carbon fiber felt and obtain the cured carbon fiber felt with very low density, the density of the cured carbon fiber felt is 0.18 g/cm < 3 >-0.22 g/cm < 3 >, the heat conductivity coefficient is 0.19 W/mk-0. 22, the ash content is less than or equal to 28ppm, and the specific heat is 0.35-0.65 J/g.k; and the cured carbon fiber felt is particularly suitable for being applied to thermal fields such asvacuum resistance furnaces, induction furnaces, sintering furnaces and heat treatment furnaces. 本发明公开了一种固化碳纤维毡及其制备方法。该方法主要基于发泡原理来实现碳纤维在固化碳纤维毡中的均匀分布以及获得密度非常低的固化碳纤维毡，固化碳纤维毡的密度为0.18g/cm3～0.22g/cm3，导热系数为0.19W/mk～0.22，灰分≤28ppm，比热量为0.35～0.65J/g·k；特别适合真空电阻炉、感应炉、烧结炉、热处理炉等热场中应用。
