| Abstract: | In order to solve the reason for the extremely poor wettability of carbon fiber and aluminum matrix,carbon fiber surface modification,sol-gel coating and preform extrusion are used to successfully prepare carbon fiber preform coated with smooth SiO2 coating.Carbon fiber preform is an important framework for preparing carbon fiber reinforced aluminum matrix composite material by extrusion casting.The optimum process conditions for preparing the coating are pH11,TEOS∶deionized water∶absolute ethanol=1∶5∶12,and the porosity of the SiO2 coated carbon fiber preform is higher than that of the uncoated carbon fiber perform,with an average porosity of 71.5%,which provides a good solution for preparing high porosity carbon fiber preform. |
