FABRICATION OF ARTIFACTS OUT OF GLASSY-CARBON AND CARBON-FIBER-REINFORCED CARBON FOR BIOMEDICAL APPLICATIONS

Polymeric carbons1 are produced by the carbonization of a wide range of organic polymeric systems. We have concentrated on the fabrication of two types of polymeric carbons, glassy carbon and carbon‐fiber‐reinforced carbon (CFRC), both involving phenolic resin precursors. We describe herein the technology which enables us to make dental implants and heart valves out of glassy carbon. We also show how carbon‐fiber‐reinforced carbon can be made in the form of rods and plates for orthopedic use and molded before firing to produce complex, rigid, individually sculptured shapes suitable for maxillofacial bone replacement. The mechanical properties will be discussed in relation to the structure of these various forms of polymeric carbon. The main purpose of the work is to show that the technology of polymeric‐carbon manufacture is essentially simple and the manufacturing process is readily carried out in laboratories which have already been equipped to fabricate standard dental prostheses.
