A method is provided to fabricate a carbon-carbon (C/C) composite valve (15) comprising machining a carbon-carbon composite valve stem having a flared end (13) and a non-flared end (11) from a cured and densified carbon-carbon plate having a sufficient thickness. Applying a plurality of circular fabric plies coaxially onto the non-flared end of the carbon-carbon valve stem and advancing the plies to contact the flared end of the valve stem. Placing the carbon-carbon valve stem contacted with the plurality of circular fabric plies into a die, closing the die, and cure pressing the plies onto the flared end of the carbon-carbon valve stem to form a valve head. Carbonizing the press cured carbon-carbon composite valve, densifying the carbon-carbon composite valve structure, and coating at least one of the carbon-carbon valve stem and valve head with a high temperature resistant coating comprising an inner and an outer layer.
