PROCESS FOR IMPROVING CREEP AND STRESS RELAXATION OF FIBER REINFORCED POLYMER COMPOSITES
Disclosed herein are composite materials comprising a siliconized carbon fiber fabric and polymeric sizing. In one embodiment, the polymeric sizing can be bismaleimide, an epoxy resin, or both. In another embodiment, the composite materials possess mechanical strength and durability and acceptable performance after extended periods of time in storage. In another embodiment, disclosed herein is a method for making the composite materials, the method including at least the steps of (a) siliconizing the carbon fiber fabric to produce a siliconized carbon fiber fabric; and (b) applying a polymeric sizing material to the siliconized carbon fiber fabric to create the composite material. In yet another embodiment, disclosed herein are composite materials formed by the disclosed process and articles comprising the composite materials including, but not limited to, camping equipment, military equipment, clothing, sporting equipment, aerospace equipment, wrinkle-free fabric, or any combination thereof.
CARRIER WITH LOCALIZED FIBROUS INSERT AND METHODS
A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.
COMPOSITE CARBON FIBER LAMINATE FOR AN INFORMATION HANDLING SYSTEM
A composite carbon fiber laminate, including a first carbon fiber woven fabric layer, including one or more first voids defined between fabric strands of the first carbon fiber woven fabric layer; a second carbon fiber woven fabric layer, including one or more second voids defined between fabric strands of the second carbon fiber woven fabric layer; a core fabric layer; a first reflective layer positioned between the first carbon fiber woven fabric layer and the core fabric layer; and a second reflective fabric layer positioned between the second carbon fiber woven fabric layer and the core fabric layer, wherein the first reflective layer reflects light that is incident upon the first carbon fiber woven fabric layer at the one or more first voids.
WEARABLE ITEMS
Wearable item comprising a motion control system and a method of manufacturing thereof. The wearable item comprises a body-close wearable item which, when worn by a user, at least a part of the wearable item is positioned adjacent to the body of the user. The motion control system comprises at least one layer of strain-rate sensitive material configured to control motion of one or more body parts of the user.
Multi-Layer Insulator for Thermal Run-Away Containment in Lithium-Ion Batteries
A multi-layered composite insulation material includes a first and second outer layers having one or more of para-aramid, meta-aramid, flame-retarded modacrylic, or pre-oxidized polyacrylonitrile fibers; and an inner layer disposed between the first and second outer layers having one or more of polyacrylonitrile fibers or ceramic fibers. The inner and outer layers are bonded via needle punching, thermal bonding, or stitch bonding. The outer layers further include flame-retardant rayon fibers and a woven or knit fabric having continuous high-temperature glass, silica, or ceramic filaments.
NEW OR IMPROVED MICROPOROUS MEMBRANES, BUILDING MATERIALS COMPRISING THE SAME, AND METHODS FOR MAKING AND USING THE SAME
In at least one embodiment, a building material comprising a porous membrane having a moderate to high water vapor permeability and high liquid water penetration resistance is disclosed. The building material may be used in building applications, including as or as part of a building wrap, a rain screen, a roofing underlayment, a flashing, a sound proofing material, or an insulation material. The porous membrane may include at least one thermoplastic polymer, at least one filler, and at least one processing oil. The porous membrane may be flat or may have ribs. The porous membrane may include at least one scrim component.
ROOFING SYSTEMS UTILIZING CAP SHINGLES WITH SELF-SEALING ADHESIVES
A roofing system including a cap shingle and a method of producing a cap shingle are disclosed. In one embodiment, the cap shingle is formed with a continuous or discontinuous self-sealing adhesive that is applied along a ridgeline direction and can provide high wind resistance, without the use of hand-sealed adhesive application. In an embodiment of the method, one or more layers of a shingle material can be oriented in a machine direction with the self-sealing adhesive applied adjacent side edges of the shingle material to form the cap shingles having self-seal strips and configured to bend in the machine direction for installation of the cap shingles along a ridge of a roof.
Flexible carbon fiber decorative veneer
A flexible carbon fiber decorative veneer may include a veneer panel assembly with a face layer formed from a carbon fiber material, a backing layer formed from a flexible fleece, and an adhesive configured to attach the face layer to the backing layer through activation via at least one joining process. The backing layer may be configured to prevent light from passing through voids or interstitial spaces in the carbon fiber material of the face layer when the backing layer is attached to the face layer via the adhesive. The flexible carbon fiber decorative veneer may be configured for use on an aircraft interior structure, the base structure for which being fabricated from an aviation honeycomb layer and a back panel. The veneer panel assembly may be configured to conform to a radius of at least 0.25 inches on the aircraft interior structure.
ISOCYANATE-REACTIVE COMPOSITIONS, POLYURETHANE FOAMS FORMED THEREFROM, MULTI-LAYER COMPOSITE ARTICLES THAT INCLUDE SUCH FOAMS, AND METHODS FOR THEIR PREPARATION
Isocyanate-reactive composition that include a polyol blend, a blowing agent composition, and a catalyst. The polyol blend includes a polyether polyol having a functionality of 2 to 6 and an OH number of 20 to 50 mg KOH/g, which is present in an amount of at least 30% by weight, based on total weight of the isocyanate-reactive composition, and an aromatic polyester polyol having a functionality of 1.5 to 3 and an OH number of 150 to 450 mg KOH/g, which is present in an amount of at least 40% by weight, based on total weight of the isocyanate-reactive composition. The blowing agent composition includes water, the water being present in an amount of 1 to 20% by weight, based on total weight of the isocyanate-reactive composition and in an amount of at least 90% by weight, based on total weight of the blowing agent composition.
