Composite materials include a steel matrix with structural aramid formed of individual fibers penetrating into the matrix at substantial depth. The fibers typically have defined diameters and large ratios of penetration depth to fiber diameter. Specified methods for forming the composite materials have a unique ability to achieve the large ratios of penetration depth to fiber diameter.

One aspect of the present invention provides a composite sheet which comprises a nitride sintered body having a porous structure and a semi-cured product of a thermosetting resin composition impregnated into the nitride sintered body, the line roughness Rz specified by JIS B 0601:2013 of at least one main surface being 10 m or less.

The present disclosure describes thermally insulating glass laminates that mitigate or prevent heat loss from heated cavities. In some embodiments, the thermally insulating glass laminates comprise a non-uniform low or non-conductive coating layer that forms a chemical bond with at least one inner surface of the substrates, wherein the coating layer can have a thickness of about 0.010 inches or less and forms a pattern that contacts about 30% or less of at least one inner surface of a substrate and helps form a plurality of sealed cavities of gas molecules between the substrates. Since there is a small amount of gas molecules in each cavity, convective heat transfer between the substrates is minimized thereby minimizing heat loss through the laminates into the surrounding environment.

Ceramic matrix composite airfoils for gas turbine engines are provided. In an exemplary embodiment, an airfoil includes opposite pressure and suction sides extending radially along a span.

Provided is a joint manufacturing method including: a step A of preparing a laminate in which two objects to be joined are temporarily adhered with a heat-joining sheet including a pre-sintering layer interposed between the two objects to be joined; a step B of increasing a temperature of the laminate from a temperature equal to or lower than a first temperature defined below to a second temperature; and a step C of holding the temperature of the laminate in a predetermined range after the step B, in which the laminate is pressurized during at least a part of the step B and at least a part of the step C.
