Variable areal density cross-plied fiber-reinforced composite ballistic material
This technology relates materials that are stab, spike and ballistic resistant and to stab, spike and ballistic resistant composite articles incorporating uniaxially oriented, non-woven fabrics. A fabric layer having a non-uniform areal density is formed having thick areas and thin areas, the thick areas having a greater filament/tape concentration compared to the thin areas. In said thick areas, agglomerated tapes/filaments will protrude from the fabric layer surface. Additional layers are then adjoined with the non-uniform layer to form a panel that has stab, spike and ballistic resistance, with protrusions at least partially spacing the additional layers from full, direct contact with the surface of the non-uniform fabric layer to thereby enhance flexibility and stab, spike and ballistic resistance of the whole.
INSTALLATION AND METHOD FOR PRODUCING A SINGLE- OR MULTI-LAYER NONWOVEN
An installation and a method for selectively producing a single-ply or alternatively a multi-ply nonwoven includes an inclined wire former configured to deposit a sheet of wet-laid fibre material on a first circulating belt, a further belt configured to receive the sheet of wet-laid fibre material from the first circulating belt, a roller card arranged downstream in the material transport direction and configured to introduce a roller card web into the installation, a hydroentanglement arranged downstream in the material transport direction and including at least one water beam configured to entangle, bond and/or structure a single sheet of fibres or a plurality of sheets of fibres, and a dryer arranged downstream in the material transport direction
A STITCHED MULTI-AXIAL REINFORCEMENT
A stitched multi-axial reinforcement and a method of producing a stitched multi-axial reinforcement. The stitched multi-axial reinforcement may be used in all such applications that reinforcements are generally needed and especially in such applications where either Vacuum Infusion technology or Resin Transfer Molding (RTM) technology for distributing the resin in the mold is used. The stitched multi-axial reinforcement is especially applicable in the manufacture of wind turbine blades, boats, sporting equipment, storage tanks, bus, trailer, train and truck panels, etc., and generally in all such structures that are subjected to stress in more than one direction
COMPOSITE COOLING FILM COMPRISING A REFLECTIVE MICROPOROUS LAYER AND A UV-ABSORBING LAYER
A composite cooling film includes a reflective microporous layer that comprises a continous phase comprising an organic polymer, an ultraviolet-absorbing layer of organic polymeric material that is disposed outwardly of the reflective microporous layer, and an anti soiling layer being disposed outwardly of the reflective microporous layer.
Sound absorption panel
In a sound absorption panel formed by stacking a plate perforated with a hole having a hole size smaller than a fiber length such as expanded metal, a honeycomb material, and felt-like fiber between the perforated plate and the honeycomb material, and joining the perforated plate, the felt-like fiber, and the honeycomb material to each other with an adhesive, the adhesive applied to the perforated plate is permeated into a surface of the felt-like fiber exposed from the hole to fix the fiber on the surface.
Aramid fabric having excellent adhesion to polyurethane matrix resin and excellent tensile strength, method for producing same, aramid fabric prepreg comprising same and aramid fabric/thermoplastic polyurethane matrix resin composite comprising same
An aramid fabric having excellent adhesion to a polyurethane matrix resin and excellent tensile strength is produced by the method including the steps of: (i) weaving a basket-structured aramid fabric by using aramid yarns as warp and weft yarns; and then (ii) dipping the woven aramid fabric in a sizing agent solution consisting of an aqueous polyurethane resin as a sizing agent and water, followed by squeezing and drying. In the present disclosure, the sizing agent is applied to the woven aramid fabric, thereby effectively preventing the deterioration in weaving efficiency. Further, the aramid fabric is woven in a basket weave, and thus the compactness of the aramid fabric is lowered and the wetting property of the aramid fabric with the polyurethane matrix resin is improved.
Non-woven backing for press felt, method for producing non-woven backing, and press felt
A press felt is provided including a non-woven base fabric material formed of a first fabric structure, with the first fabric structure including an array of MD yarns connected with at least one layer of a hot melt adhesive web material and at least one layer of a non-woven backing. The non-woven backing includes a layer of a first yarn system and a layer of a second yarn system oriented transverse to the first yarn system. At least one of the first and second yarn systems includes a low melt temperature adhesive that is heat activated and binds the first and second yarn systems together. The nonwoven base fabric material has an MD length and CD width and is arranged in two superimposed layers joined by the MD oriented yarns at CD oriented fold regions at each of two opposing ends thereof.
Multi-layer woven fabric article
A multi-layer article of woven fabric includes a woven base layer; a woven mesh layer, disposed above the base layer, the mesh layer utilizing a first common warp for each one of a plurality of stacked wefts; and a woven binding layer, disposed above the mesh layer. The base layer and the binding layer share a second common warp.
