A sliding member has pore-dense portions in which pores are densely packed on a sliding surface of a main body made of a ceramic.

A thermally-insulating composite material with co-shrinkage in the form of an insulating material formed by the inclusion of microballoons in a matrix material such that the microballoons and the matrix material exhibit co-shrinkage upon processing. The thermally-insulating composite material can be formed by a variety of microballoon-matrix material combinations such as polymer microballoons in a preceramic matrix material. The matrix materials generally contain fine rigid fillers.

A thermal formation sintering compound containing a binder, a sinterable powder material and a pore formation material, for formation into a predetermined shape in a thermal formation step, removal of the binder in a degreasing step, and sintering of the powder material in a sintering step is provided. The binder contains a low-temperature draining component which melts in the thermal formation step, begins draining at a temperature lower than a draining temperature of the pore formation material, and drains at a temperature lower than a temperature at which the pore formation material drains; and a high-temperature draining component which melts in the thermal formation step, begins draining after the pore formation material begins draining, and drains at a temperature higher than does the pore formation material.

A method of forming a composite component is provided. The method includes locating a fibrous preform, providing a slurry, mixing the slurry with sacrificial fibers, injecting the slurry into the fibrous preform, heating the fibrous preform, forming channels in the fibrous preform, and densifying the fibrous preform. The sacrificial fibers are suspended in the fibrous preform along an injection pathway such that heating the sacrificial fibers forms the channels along the injection pathway as the sacrificial fibers are burned away.

The present disclosure relates to a method of fabricating a ceramic composite components. The method may include providing at least a first layer of reinforcing fiber material which may be a pre-impregnated fiber. An additively manufactured component may be provided on or near the first layer. A second layer of reinforcing fiber, which may be a pre-impregnated fiber may be formed on top the additively manufactured component. A precursor is densified to consolidates at least the first and second layer into a densified composite, wherein the additively manufactured material defines at least one cooling passage in the densified composite component.

A manufacturing method of a heat shield component includes a mixing step of mixing sol including a ceramic precursor with heat-expandable microspheres having an outer shell formed of thermoplastic resin and encapsulating a foaming agent so as to obtain a mixed solution, a coating step of applying the mixed solution to a substrate to obtain a coated product, and a heating step of heating the coated product to form a base body including a ceramic from the ceramic precursor, and leading the heat-expandable microspheres to foam so as to form a ceramic porous layer including closed pores in the base body. The ceramic porous layer has a porosity in a range of 40% to 70%.

The invention generally relates to foam ceramics (3) and to filters comprising such a foam ceramic, and to a method for producing foam ceramics and filters comprising or made of such a foam ceramic. Another aspect relates to the use of the foam ceramic (3) and of a filter comprising or made of such a foam ceramic.
