Abstract

The invention discloses a device for continuously fabricating carbon fiber felt production line and a technique thereof, which is implemented by a production line support device, a dynamical system, an electric heating and temperature controlling system and a felt material dipping system. The invention is characterized in that one end which is rolled into a felt blank roll is put into a felt material dipping pool along a felt containing machine; then the end sequentially enters a low-temperature oxidation furnace, an intermediate-temperature oxidation furnace and a high-temperature oxidation furnace; the end enters a lower-temperature carbide furnace, a middle-temperature carbide furnace and a high-temperature carbide furnace after passing through an oxidation felt dipping pool; at last, the end extends out and enters a felt receiving machine and a felt shelf disk shelf to be rolled to obtain finished products; the width of the product is 900-1200mm, the thickness is 3-12mm, tensile strength (N / 25mm) longitude / latitude is 14 / 16, surface density (g / m) is 1500-1800, carbon content is 86-94%, square resistance (omega / 25mm) (11) is 0.1, and thermal conductivity (J / cm.s DEG C) is 4.6*10 52 DEG C. The invention can achieve the aim of continuously fabricating carbon fiber felts.

Description

technical field [0001] The invention relates to the field of carbon fiber composite material manufacturing, in particular to equipment and technology for a continuous carbon fiber felt production line. Background technique [0002] The production of traditional carbon fiber felt is as follows: polyacrylonitrile fiber is pre-oxidized to make pre-oxidized felt or carbon fiber is cut and carded into a web, and then needle-punched into an extra-thick carbon fiber felt slab, and then treated at high temperature to form a carbon fiber felt. ; Then carry out high temperature treatment to make carbon fiber felt. Compared with other thermal insulation materials, carbon fiber felt has the following characteristics: high temperature resistance (up to 3000°C in vacuum or protective gas), can effectively block radiant heat, and has a very small amount of outgassing, especially suitable for use in vacuum high temperature furnaces . Resistant to various chemical corrosion, light weight c...
