Abstract: The invention relates to a method for manufacturing a fiber-reinforced bioactive ceramic implant, wherein a base form is made from fibrous material and interspaces between the different fibers are filled using chemical vapor phase infiltration. The fibrous material is coated with a composition which optimizes the bonding with the infiltrant. Preferably, a calcium-phosphate compound is brought between the fibers, which are preferably of the continuous-fiber type.
