Aqueous polyurethane dispersion adhesive compositions

An aqueous polyurethane dispersion compositions are disclosed. The compositions include a polyurethane prepolymer dispersed in an aqueous medium, the polyurethane prepolymer comprising an isocyanate and a crystalline polyester polyol having a hydroxyl content of 20 to 150 mg KOH/g and a melt temperature of less than or equal to 90° C. Methods of forming a laminate are also disclosed. The methods include providing an aqueous polyurethane dispersion, applying the polyurethane dispersion to a surface of the first substrate, bringing the side of the first substrate into contract with a surface of the second substrate, and curing the aqueous dispersion, thereby laminating the first substrate to the second substrate. Laminates formed by the methods and including the compositions are also disclosed.

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.

20230052973 · 2023-02-16 ·

A thermally adaptive material configured to assume a lofted configuration and flat configuration in response to different temperatures. The thermally adaptive material includes an adaptive first textile layer with one or more sections of a first material that has a first thermal expansion coefficient and one or more sections of a second material disposed adjacent to the one or more sections of the first material, the one or more sections of the second material having a second thermal expansion coefficient that is different from the first thermal expansion coefficient. The thermally adaptive material also includes a second textile layer disposed opposing the adaptive first textile layer; a plurality of engaging portions between the first textile layer and second textile layer; and one or more cavities defined by the first and second layers that are generated while the adaptive textile is at least in a lofted configuration.

Surface features for locating net substrate buttons to enable self-piercing riveting (SPR) on brittle and low toughness materials

A dimpled substrate for use in an assembly having joined substrates is provided that defines at least one preformed interior cavity, at least one preformed exterior profile adjacent the interior cavity and defining a wall therebetween, and at least one locating feature configured to identify a location of the at least one preformed exterior profile. In one form, the locating feature is disposed in the preformed exterior profile or adjacent to the preformed exterior profile. Alternatively, the locating feature is a notch formed into the dimpled substrate away from the preformed exterior profile.
