A reinforced tapered edge cementitious skin for use in a SIP panel provides a recessed edge having an underlying reinforcing web. When panels having the reinforced tapered edges are to be joined together and fastened to underlying shims, the resulting joint has both structural integrity and a recess for receiving joint compound that can be made flush with the skins.

A ceramic die for a hot press is provided, along with a method of constructing a ceramic die. The ceramic die includes a ceramic die body defining a mold surface configured to shape a part during a superplastic forming process. The mold surface defines at least one curved surface and at least one non-curved surface, spaced apart from the at least one curved surface. The ceramic die also includes a plurality of fibers disposed within the ceramic die body. The plurality of fibers may be preferentially located proximate the at least one curved surface such that a first portion of the ceramic die body proximate the at least one curved surface has a greater percentage of fibers than a second portion of the ceramic die body proximate the at least one non-curved surface.

A method for densifying a fibrous texture made of ceramic material with a ceramic matrix used in injection equipment including a mold cavity defined between a mold and a counter-mold, the mold cavity defining an internal space, and a membrane comprising a stiffened zone, the membrane being intended to be placed between a fibrous texture present in the mold cavity and the counter-mold, and the stiffened zone of the membrane having a Young's modulus greater than 200 GPa, the method including placing a predensified fibrous texture in the mold cavity, the predensified fibrous texture having corrugations on the surface and placing the membrane on the predensified fibrous texture in such a way that the stiffened zone of the membrane is in contact with the peaks of the corrugations of the predensified fibrous texture; closing the injection equipment, and densifying.

A radiant heating panel, for typical use as cover for interior walls and ceilings, is provided, that is manufactured in a continuous process involving at least one sheet material, a settable material and a heating element. A method of installing such a heating panel is also provided, along with an apparatus and method required to terminate the heating panel.

A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out. In addition, the packing of the settable material and maximum space between the faces are such that only a predetermined amount of liquid can be accommodated within the space and that amount is matched to the water required to set the cement.

A method for densifying a fibrous texture made of ceramic material with a ceramic matrix used in injection equipment including a mold cavity defined between a mold and a counter-mold, the mold cavity defining an internal space, and a membrane comprising a stiffened zone, the membrane being intended to be placed between a fibrous texture present in the mold cavity and the counter-mold, and the stiffened zone of the membrane having a Young's modulus greater than 200 GPa, the method including placing a predensified fibrous texture in the mold cavity, the predensified fibrous texture having corrugations on the surface and placing the membrane on the predensified fibrous texture in such a way that the stiffened zone of the membrane is in contact with the peaks of the corrugations of the predensified fibrous texture; closing the injection equipment, and densifying.

A method for manufacturing cladding elements for use in construction, including a composite cement-based structure, including an elastically deformable support element having a first surface, a second surface and a plurality of spacer elements having an elongated shape positioned between the first and second surface to realize a plurality of interconnected cavities. The method further provides preparing a substantially fluid and water-based cementitious composition and introducing the substantially fluid cementitious composition into the support element to obtain a composite structure in a deformable state. After this, part of the fluid cementitious composition is removed from the support element, to eliminate the excess fluid cementitious composition and position the deformable composite structure in a forming device. The method provides for maintaining the deformable composite structure in association with the forming device, until the consolidation thereof and that said support element is constituted by a three-dimensional elastically deformable fabric.

A method of forming a lightweight concrete comprising lightweight aggregates (LWA) made from recycled materials and the resulting composition. The lightweight concrete may be formed by adding calcium sulfoaluminate (CSA) cement and a specialized grout to an amount of water in a mixer, wherein a ratio of the water to the CSA cement is 1 quart to every 10 lbs of CSA cement. The CSA cement, specialized grout, and water may be blended to a smooth consistency. LWA may be added to the blended CSA cement, specialized grout, and water, wherein a ratio of the CSA cement to LWA is 60/40 by weight. The mixture of LWA, CSA cement, specialized grout, and water may be poured over a fiberglass rebar. The mixture may be allowed to cure and before being densified with a lithium densifier.

A ceramic matrix composite (CMC) vane includes a first platform, a second platform, at least one airfoil extending between and connected to the first platform and the second platform, and at least one integral transition region between the at least one airfoil and the first platform. The airfoil includes a shear tube layer positioned to abut the second platform. A first continuous single-folded fiber sheet forms the first platform, the at least one airfoil, and the at least one integral transition region and an additional fiber sheet overwraps the shear tube layer and the second platform to form a shear tube transition region.

A lightweight concrete including calcium sulfoaluminate (CSA) cement, the CSA cement comprising lithium silicate formed from a reaction with a concrete lithium densifier, a grout comprising one or more types of Portland cement, and lightweight aggregates (LWA) suspended by a fiberglass rebar, wherein a ratio of the CSA cement to the LWA is 60/40 by weight.
