摘要：Methods are disclod for producing architectural preforms and high-
temperature composite structures containing high-strength ceramic fibers with reduced preforming stress within each fiber, with an in-situ grown coating on each fiber surface,
电子商务推广方案with reduced boron within the bulk of each fiber, and with improved tensile creep and rupture resistance properties for each fiber. The methods include the steps of preparing an original sample of a preform formed from a pre-lected high-strength silicon carbide ceramic fiber type, placing the original sample in a processing furnace under a pre-lected preforming stress state and thermally treating the sample in the processing furnace at a pre-lected processing temperature and hold time in a processing gas having a pre-lected composition, pressure, and flow rate. For the high-temperature composite structures, the method includes additional steps of depositing a thin interpha coating on the surface of each fiber and forming a ceramic or carbon-bad matrix within the sample.美国间谍
