Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.

An airfoil for a gas turbine engine is provided that includes a first portion formed from a first plurality of plies of a ceramic matrix composite material and defining an inner surface of the airfoil, as well as a second portion formed from a second plurality of plies of a ceramic matrix composite material and defining an outer surface of the airfoil. The first portion and the second portion define a non-line of sight cooling aperture extending from the inner surface to the outer surface of the airfoil. In one embodiment, a surface angle that is less than 45 is defined between a second aperture and the outer surface. A method for forming an airfoil for a gas turbine engine also is provided.

The present invention involves a multiplayer artificial stone and its preparation method. The decorative layer comprises the following components in percentage by weight: 80%-90% of a decorative stone, 5%-15% of an unsaturated polyester resin, 0.6%-2% of a coupling agent, 0.7%-1.2% of a curing agent, and 1%-5% of a pigment filler. The bottom layer comprises the following components in percentage by weight: 65%-78% of a calcium carbonate stone, 10%-18% of an unsaturated polyester resin, 0.6%-2% of a coupling agent, 0.7%-1.2% of a curing agent, and 1-15% of a pigment filler. The preparation method involves preparing the decorative layer and the bottom layer separately and then binding the two layers together by pressing. This arrangement allows the multilayer artificial stone to have good decorative effect and product quality; in addition, each layer contains only one type of stone, therefore its preparation is easier and can be more precisely controlled, lowering production cost.
