It seemed that the fiber and the matrix did not creep themselves in the range of the testing stress and temperature, so the matrix microcracking and interfacial sliding will be the main contributer to the macroscopic deformation of the three-dimensional c / sic composite 由于在所測定的溫度區(qū)間和應(yīng)力范圍內(nèi),碳纖維和基體本身都不大可能發(fā)生蠕變。因此,基體開裂和界面的滑動是3d-csic復(fù)合材料宏觀變形的主要貢獻(xiàn)者。
