  • Method and apparatus for impregnating a continuous fiber reinforcement
    Patent number: 10183309
    Abstract: A continuous ceramic matrix composite strip is produced by passing a dry ceramic fiber strip through a ceramic slurry bath. Impregnation wheels within the bath guide the fiber strip through the bath and force the ceramic slurry into the fiber strip, thereby impregnating the strip. The impregnation wheels stir the ceramic slurry to maintain a homogeneous mixture. Air knives remove excess slurry from the strip. Thickness and width controls squeeze the impregnated strip to desired thickness and width dimensions.
