With the silane-treated clay production method, a functional silane is predispersed or emulsified in water by means of a surfactant in order to mix the functional silane with kaolin clay and thereby uniformly surface-treat the kaolin clay with the functional silane.

Abstract: The present invention is of a cementitious composition containing OPC, calcined gypsum, a source of amorphous silica and a source of amorphous alumina. The ratio of calcium sulfate hemihydrate to OPC is 0.7:1.0 to 1.4:1.0, the ratio of amorphous silica and amorphous alumina to OPC is 0.26:1.0 to 0.4:1.0, and the ratio of amorphous alumina to amorphous silica is 0.3:1.0 to 1.5:1.0.

Abstract: An assemblage for bonding the skin of an airfoil to the core of the airfoil includes a hybrid caul plate assembly for covering the surface of the airfoil assembly which is exposed to bonding pressure. The hybrid caul plate includes a central elastomeric component and peripheral semi-rigid metal components. The semi-rigid metal components are formed from a steel sinusoidal mesh and are axially elongated. The mesh is flexible in the direction of elongation, but are rigid in the transverse direction. The peripheral semi-rigid caul componnents will thus closely conform to the contours of the core in the axial direction, and will, at the same time, provide support for the edges of the core so that the core edges will not be crushed or deformed by bonding pressure applied to the assemblage during the skin-to-core bonding process. The result of using the hybrid caul plate assembly is an improved skin-to-core bond wherein bridging or voids in the bond line at the periphery of the airfoil are avoided.
