ABSTRACT:
A light-weight fiber brick is formed from a water-fiber suspension including ceramic fibers. A molding device is introduced into the suspension and has plurality walls including at least three walls each of which extends perpendicular to the other two of the three walls. Water is withdrawn simultaneously from the interior of the molding device through at least the three walls, thus causing the fibers of the suspension to tend to align longitudinally within the interior of the molding device in three spatial coordinate directions (X, Y, Z). Thereby there is formed a brick having fibers thereof aligned with longitudinal directions thereof having directional components in three spatial coordinate directions.
