Abstract
The fatigue characteristics of the carbon fiber reinforced carbon composites (CFRC) material are necessary for the advanced industries requiring the thermal resistance. The research and development of CFRC have been in progress in the field of aerospace and defense industry. In this paper, we investigated the fatigue characteristics of CFRC by using an aircraft brake disk system. As the results of a series of tensile tests, the tensile strengths of CFRC were appeared 102.8 MPa ($0^{\circ}$), 98.6 MPa ($60^{\circ}$), and 95.5 MPa ($90^{\circ}$), respectively. It was showed that CFRC had better tensile property than the usual composite materials. As the results of fatigue tests, the fatigue limit was ~ 77 MPa, which is under the 75% of the maximum tensile load. CFRC is recommended as a strong potential composite materials because the carbon fibers are closely packed and strongly bonded between the carbon fibers.
