Abstract: A method of forming a pre-form ceramic matrix composite mold for a ceramic matrix composite (CMC) component including providing pieces of CMC remnant scrap material and randomly arranging the pieces of CMC remnant scrap material relative to one another. The method further includes debulking the pieces of CMC remnant scrap material into a rigidized shape, the rigidized shape having gaps between adjacent pieces of CMC remnant scrap material of about 10 microns and about 10 mm and a gap spacing between about 50 microns and about 50 mm, and forming the rigidized shape into a mold.

Abstract: A turbine apparatus is disclosed including a first article and a second article disposed between the first article and a hot gas path of a turbine. The first article includes at least one first article cooling channel in fluid communication with and downstream from a cooling fluid source, and the second article includes at least one second article cooling channel in fluid communication with and downstream from the at least one first article cooling channel. A method for redundant cooling of the turbine apparatus is disclosed including flowing a cooling fluid from the cooling fluid source through at least one first article cooling channel, exhausting the cooling fluid from the at least one first article cooling channel into at least one second article cooling channel, and flowing the cooling fluid through the at least one second article cooling channel.
