Abstract
A carbon material having a continuous porous structure oriented to the stretching axis is provided, which carbon material can be used as a structural material excellent in interfacial adhesion. The porous carbon material has a continuous porous structure in at least a portion thereof, in which the continuous porous structure has an orientation degree measured by a small-angle X-ray scattering method or an X-ray CT method of 1.10 or more.

9. A process for producing a porous-carbon-material precursor, the process comprising:
-
step 1;
a step in which a carbonizable resin and an eliminable resin are brought into a compatibly mixed state to obtain a resin mixture;step 2;
a step in which the resin mixture obtained in the step 1 is molded and caused to undergo phase separation, thereby obtaining a precursor material having a co-continuous phase separation structure; andstep 3;
a step in which the precursor material obtained in the step 2 is subjected to stretching. - View Dependent Claims (10, 11, 12)
