ABSTRACT:
An apparatus and a method of producing a high density fiber reinforced composite material operate for lowering the porosity of a porous fiber reinforced composite material. A large number of particles arranged in a reaction tube are pushed up by the pressure of gases flowing from a gas inlet port toward a gas outlet port to enter floating states and to collide with the porous fiber reinforced composite material which is fixed in the reaction tube. In this state, matricies are formed in pores of the porous fiber reinforced composite material through chemical vapor infiltration. The large number of floating particles prevent an adhesion between the surface of the porous fiber reinforced composite material and blocking with soot, while preventing the pores from blocking with soot.
