摘要： A dual mode radar transparency allowing passage of both RF radiation and IR radiation comprises an aerogel base and ceramic skin overlaying the aerogel base. The aerogel base comprises a low density ceramic material. A method of fabricating a dual mode radar transparency allowing passage of both RF radiation and IR radiation comprises the steps of preparing a colloidal dispersion of a ceramic material in a medium, increasing a concentration of the colloidal dispersion by evaporation to create a suspension, and placing the suspension in a mold. The suspension is solidified to form an aerogel and the aerogel is joined to a ceramic skin.

摘要： A ceramic matrix composite wall structure (20A) constructed of interlocking layers (22A, 24A) of woven material with integral cooling channels (28A, 32A). The CMC layer closest to the hot gas path (41) contains internal cooling tubes (26A, 30A) protruding into a ceramic insulating layer (40A). This construction provides a cooled CMC lamellate wall structure with an interlocking truss core.

摘要： A ceramic matrix composite (CMC) material (10) with increased interlaminar strength is obtained without a corresponding debit in other mechanical properties. This is achieved by infusing a diffusion barrier layer (20) into an existing porous matrix CMC to coat the exposed first matrix phase (19) and fibers (12), and then densifying the matrix with repeated infiltration cycles of a second matrix phase (22). The diffusion barrier prevents undesirable sintering between the matrix phases and between the second matrix phase and the fibers during subsequent final firing and use of the resulting component (30) in a high temperature environment.

摘要： A method of forming a ceramic matrix composite (CMC) article (30) or a composite article (60) that minimizes the risk of delaminations while simultaneously maintaining a desired degree of porosity in the material. A pressure P applied against a surface of the article during a sintering process is controlled to be high enough to resist a separation force between the plies (66) of the CMC material (62) caused by anisotropic shrinkage of the material and/or to resist a separation force caused by differential shrinkage between the CMC material and an adjoined monolithic ceramic material (64). The pressure is also controlled to be low enough to avoid undue consolidation of the materials and to provide a desired degree of porosity in the sintered article. The pressure may be applied by delta-alpha tooling, and it may be varied verses the time of the sintering heating and/or across the article surface.
摘要翻译：一种形成陶瓷基质复合材料（CMC）制品（30）或复合制品（60）的方法，其最小化分层的风险，同时保持材料中期望的孔隙度。在烧结过程中施加到制品表面的压力P被控制到足够高以抵抗由材料的各向异性收缩和/或抵抗引起的CMC材料（62）的层（66）之间的分离力由CMC材料和邻接的整体陶瓷材料（64）之间的不均匀收缩引起的分离力。压力也被控制到足够低以避免材料的不适当的固结并且在烧结制品中提供期望的孔隙度。压力可以通过Δ-α加工来施加，并且可以随烧结加热时间和/或穿过制品表面而变化。

摘要： A mold system for producing components of a turbine engine. The mold system may enable a configuration of a turbine engine component to be changed in less time than conventional systems. The mold system may include a mold formed from mold plates wherein at least one of the mold plates has at least one mold cavity configured to receive a ceramic insert and a ceramic insert positioned in the at least one mold cavity and including a core making cavity. The ceramic insert may be formed from a material having high compressive strength, good wear resistance, good corrosion resistance, good thermal conductivity, and high toughness, such as but not limited to, graphite partially or fully converted to silicon carbide, silicon carbide, graphite coated with silicon carbide, and other appropriate materials. The ceramic insert may also be formed with other near net shape processes, such as, reaction bonded metal oxides.
