Ceramic Matrix Composites Move Into Turbine Hot Sections
Silicon carbide fibre reinforced composites solve the brittleness that kept monolithic ceramics out of rotating and load-bearing turbine hardware, and they operate several hundred degrees above the superalloys they replace while weighing roughly a third as much. Around 340 engine programmes now specify composite components in shrouds, liners and nozzles. Manufacturing remains slow and expensive, since fibre production, preform layup and melt infiltration each take a considerable amount of time. Cost falls steadily with volume, and qualification rather than demand is what currently limits how quickly this segment can scale.
