THE FRACTURE TOUGHNESS OF SEVERAL ROCKET NOZZLE THROAT MATERIALS
Source abstract
Abstract
The fracture toughness of several rocket nozzle throat materials was investigated at room temperature. Their fracture microstructure and fracture mechanism were also qualitatively analyzed. The results indicate that, the fracture toughness of copper impregnated graphite is not much greater than that of graphite at room temperature, because the liquid copper does not wet the graphite. The two kinds of integral C/C felt have almost the same fracture toughness though they have a different matrix carbon. The content and distribution of the carbon fiber in the multi directional woven C/C are related to the mechanical properties of the materials.
