Abstract
The present invention relates to a carbon fiber insulator and a producing method thereof. More specifically, the present invention relates to a carbon fiber insulator which is produced from a heterogeneous laminated felt comprising a carbon fiber mat laminate having at least one carbon fiber mat laminated therein and a low carbonization rate fiber mat provided at least one of upper and lower portions of the carbon fiber mat laminate.
Claims17
A carbon fiber insulator which is produced by heat-treating a heterogeneous laminated felt comprising:
- a carbon fiber mat laminate having at least one carbon fiber mat laminated therein;
- and a low carbonization rate fiber mat provided at least one of upper and lower portions of the carbon fiber mat laminate, wherein the carbon fiber mat laminate and the low carbonization rate fiber mat are in a bound state by a needle punching in a thickness direction of the carbon fiber mat laminate.
A method of producing a carbon fiber insulator comprising:
- (a) preparing a homogeneous felt comprising a carbon fiber mat laminate having at least one carbon fiber mat laminated therein and a low carbonization rate fiber mat provided at least one of upper and lower portions of the carbon fiber mat laminate, wherein the carbon fiber mat laminate and the low carbonization rate fiber mat are in a bound state by a needle punching in a thickness direction of the carbon fiber mat laminate;
- (b) impregnating the heterogeneous laminated felt into a binder resin and curing the heterogeneous laminated felt;
- and
- (c) heat-treating the cured heterogeneous laminated felt to remove the low carbonization rate fiber mat from the heterogeneous laminated felt.
