MANUFACTURE OF CARBON FIBER REINFORCED CARBON ROD |
摘要 |
PURPOSE:To manufacture the titled rod suitable for use as a reinforcing member for the connected part of optical fibers, by forming a bundle of carbon fibers impregnated with a carbonizable resin and by carbonizing the bundle in 2 steps. CONSTITUTION:A bundle of carbon fibers such as a bundle of fibers having 3- 30mum is diameter obtd. by calcining pitch or acrylonitrile fibers is impregnated with a carbonizable resin such as phenol resin or epoxy resin to form a rod having about 0.5-2mm. diameter. The rod is optionally heat-treated at about 200- 300 deg.C for about 0.5-5hr, and it is carbonized at about 700-1,000 deg.C in an inert atmosphere and carbonized again at a higher temp. such as >=about 1,600 deg.C to manufacture a carbon fiber reinforced carbon rod having >=99% carbon content. |
