A method of forming a ceramic matrix composite component according to an exemplary embodiment of this disclosure, among other possible things includes laying up plies of ceramic reinforcement material with sacrificial plies to form a preform, infiltrating the preform with a ceramic matrix material, and machining away the sacrificial plies to reveal a surface profile of the ceramic matrix composite component. A preform for a ceramic matrix composite component is also disclosed.

Disclosed is a machinable dental bulk block that is a glass ceramic block including an amorphous glass matrix and crystalline phases introduced into the matrix. A major crystalline phase is lithium disilicate and minor crystalline phases are lithium phosphate and at least one of spodumene and virgilite. The dental block is made of a functionally gradient material in which the major crystalline phase exhibits a gradient of particle sizes in a depth direction of the dental block and which has no interface at a point where the gradient of particle sizes of the major crystalline phase changes. The dental bulk block is useful for production of a dental prosthesis (artificial tooth) similar to a natural tooth. The dental bulk block can reduce time and the number of processing steps to manufacture a dental prosthesis and provides improved structural stability through good force distribution obtained by functionally graded mechanical properties.

A method for patterning layers of 2D material by inducing self-assembly on a support substrate, the method comprising the steps of depositing a layer of 2D material on the support substrate; applying a force at a region consisting of a point, a line, or an a real region of the 2D material such that the 2D material forms a folded, self-contacting structure at that region.

A medical use honeycomb structure having a plurality of through-holes extending in one direction, wherein an outer peripheral section of the medical use honeycomb structure has a through-hole groove formed by incomplete side walls of the through-hole, and a through-hole inlet adjacent to the through-hole groove.

A molded article having a small difference in thermal conductivities between a central section and a section located at an outer peripheral surface side; and a method for producing the same; wherein, a plate-shaped molded article includes an aluminum-silicon carbide composited section in which a metal including aluminum was impregnated into a silicon carbide porous body, wherein a difference in the densities, by Archimedes’ principle, of a central section of the aluminum-silicon carbide composited section and of at least a portion of an outer side section located further toward the outside peripheral surface side than the central section is 3% or less.

Embodiments of a system and a method for manufacturing a gypsum board can be used to produce a gypsum board having at least one perforated cover sheet via a cover sheet perforator system. The cover sheet perforator system can include a perforator roller is disposed downstream of a forming station along a machine direction, a roller support frame for rotatably supporting the perforator roller such that its rotational axis extends along the cross-machine direction, and a motor arranged with the perforator roller to rotate the perforator roller about the rotational axis. The drive motor can be adapted to rotate the perforator roller with a tangential speed substantially equal to the line speed to produce a series of perforation holes in an upwardly-facing cover sheet as the gypsum board moves past the perforator roller.
