| Abstract: | The short-beam shear test was conducted on the CCF300 and T300 carbon fiber composite laminate under the condition of 23℃ dry,23℃ wet,130℃ dry and 130℃ wet.The macroshape conjunctions with the SEM image were employed for the analysis and comparison on the shear failure mode and damage mechanism of these two kinds of carbon fiber composite.The results show that the interface strength is the most important property affecting the shear strength and failure mode of carbon fiber composite.However,CCF300 carbon fiber composite shows lower property on the interface strength.Therefore,if the CCF300 carbon fiber composite want to get more widely application on the structures,it need to improve its interface strength,especially the strength that under the condition of high temperature and wet. |
