A wrappable sleeve for routing and protecting an elongate member, against exposure to high temperature, abrasion, fluid ingress, and contamination, has a multilayered wall extending widthwise between opposite edges and extending lengthwise along a longitudinal axis between opposite ends. The wall includes a textile outer layer, a textile inner layer, and an intermediate layer sandwiched between the outer layer and the inner layer. The intermediate layer includes a textile intermediate layer facing the textile inner layer and a silicone-based layer facing the textile outer layer.

Loose-fill insulating products may include mineral wool, in particular glass wool or rock wool, in the form of down, nodules, or flakes, which are obtainable by an aeration that allows the mineral wool to be expanded. The mass distribution of the agglomerates may be obtained by screening 2 to 5 g of insulating product using a vibrating sieve shaker with a stack of screens and a maximum amplitude of oscillation of 3 mm set to 1.5 to 2.5 mm, 1.8 to 2.2 mm, or 2 mm, for 5 minutes, satisfies a relationship

(% agglomerates 6-13)−(% agglomerates<6)≥5%,

where (% agglomerates 6-13) is mass percentage of agglomerates passing through 6 mm and 13 mm screens, and (% agglomerates<6) is mass percentage of agglomerates passing through a 6 mm screen.

Provided are an article having inorganic fibers and needle marks extending in the thickness direction and including vertical bundles composed of the inorganic fibers extending in the thickness direction.

Methods of making ceramic matrix prepregs are described. The methods include exposing a coated tow of ceramic fibers to a ceramic matrix slurry comprising a solvent and ceramic precursor. The coating is at least partially removed and the slurry infuses into the ceramic fibers to form prepreg. Steps to form ceramic matrix composites are also described, including forming the prepreg into a green body, and sintering the ceramic precursor.

A multi-bar warp knit fabric structure includes a body yarn and a multi-wrapped hybrid yarn. The hybrid yarn incorporates a specialty core unit, an inside textile cover, and an outside textile cover. The inside textile cover is a static-dissipative yarn helically wrapped around the core unit, and the outside textile cover is a surface-conductive yarn helically wrapped around the inside textile cover and the core unit. The hybrid yarn is integrally knit with the body yarn in a repeating stitch pattern alternately zigzaging lengthwise up selected wales of the fabric structure and floating across the fabric structure in a widthwise course direction. The hybrid yarn cooperates with like knitted multi-wrapped hybrid yarns to form a continuous conductive matrix of static dissipative boxes in the fabric structure.

Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection.

An erosion, sediment and pollution control product comprises a geotextile which includes at least 10% non-plastic non-biomass based inert threads, in particular basalt or glass threads, and cellulose based filler within the tubular geotextile. The geotextile may be knitted. A method of making a tubular knitted geotextile comprises the steps of: supplying non-plastic, non-biomass based inert threads, such as basalt or glass threads, to a circular knitting machine and knitting a tubular substrate which includes at least 10% non-plastic non-biomass based inert threads.

Systems and methods are provided for braiding Metal Matrix composite (MMC) tape. One method includes drawing multiple lanes of MMC tape, comprising a matrix of metal reinforced by fibers, from bobbins arranged around a mandrel. The method also includes braiding the multiple lanes to form a preform at the mandrel for an MMC part and consolidating the preform via application of heat and pressure.

The present application discloses and claims a method to make a flexible ceramic fibers (Flexiramics™) and polymer composites. The resulting composite has an improved mechanical strength (tensile) when compared with the Flexiramics™ respective the nanofibers alone. Additionally a composite has better properties than the polymer alone such as lower fire retardancy, higher thermal conductivity and lower thermal expansion. Several different polymers can be used, both thermosets and thermoplastics. Flexiramics™ has unique physical characteristic and the composite materials can be used for numerous industrial and laboratory applications.
