Method of manufacturing carbon-fiber/carbon composite material.

摘要

Disclosed is a method of manufacturing a carbon-fiber/carbon composite material which can improve economical efficiency while maintaining a certain degree of strength. According to the present invention, a matrix material and carbon fiber are mechanically mixed by deciding the composition from the carbonization ratio of the matrix material and the desired ratio of fiber to be contained in a resultant product. After pressure-molding the mixture, the mixture is cured, and carbonized while being further pressurized. Thus, another matrix material fills open pores left behind by the evaporated matrix material at the time of molding, curing, etc., thereby increasing the density. A carbon-fiber/carbon composite material of good quality can be provided without requiring repetition of steps. Therefore, time required for manufacturing can be reduced, and economical efficiency can be improved while maintaining a certain degree of strength. <IMAGE>
