| Abstract: | The relationship between the tightening torque and the stress distribution for a bolt was descried briefly in this paper. Then, the failure pattern and the strength performance of the C/C composite bolt with tightening torque were researched, and obtained the result that the mechanics performance of the composite bolt differs greatly from that of the metal bolt. These results are helpful for the design of composite joints. |
