A repairing or reinforcement method includes applying, to concrete, a pressure-sensitive or bonding adhesive sheet containing a first pressure-sensitive or bonding adhesive layer; and curing the first adhesive layer such that a first surface of the first adhesive layer is bonded to the concrete. The first adhesive layer contains an acrylic resin having a glass transition temperature of 15 C. or below, a liquid epoxy resin, a solid epoxy resin, and a curing agent.

For a flexible, optically clear display stack, an adhesive, a system, and a method are provided. The adhesive is formed of polymer chains, at least a portion of which are cross-linked, a non-volatile diluent having a volume % in the range of between about 40 and 95, and is characterized with a low shear modulus of less than 10 kPa. The system is formed by at least first and second optically clear thin films with the adhesive disposed between the first and second thin films. The method includes the steps to form the system.

Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.

A self-repairing inflatable article including an inflatable component that includes an interior surface and an exterior surface, a sealed flexible package adjacent to the inflatable component, and a sealant composition disposed in the sealed flexible package. The sealed flexible package is configured to release the sealant composition upon puncture, tearing or other breach of the inflatable component.

A seal-healing material that is used to form fuel tanks and other fuel containing items uses a pair of reagents disposed within multiple individual cells on either side of a polymer film with other polymer films forming the outer boundaries of each set of cells. The reagents, when mixed, chemically react to form a sealant. An elastomeric sheet is bound to each polymer film such that a fibrous material is disposed between each polymeric film and elastomeric film.

The self-supporting synthetic polymer waterproofing membrane with self-repairing properties relates to a self-repairing synthetic waterproof membrane, applicable in the construction sector. This membrane can be monolayer or multilayer. The composition of these membranes comprises thermoplastic polymers, smectite-type clays and super water-absorbent polymers.

Described are continuous fiber-reinforced composites that include a self-healing copolymer. The continuous fiber-reinforced composites are used to form self-healing products. Products include multi-layer hoses that include a self-healing layer. The self-healing layer can be sandwiched between an inner layer and an outer layer of a multi-layer hose, thus forming a self-healing multi-layer hose. Multi-layers hoses can be utilized as self-healing hydrogen dispensing hoses. Methods for forming the continuous fiber-reinforced composites and products are also described.

Provided are cementitious panel that include a swellable material within a core layer, a dense layer, and/or a sheet of facing material that make up a cementitious panel, as well as methods of manufacturing such cementitious panels that include a swellable material and methods of providing a moisture or water barrier in a cementitious panel.

A fuel cell containing fuel for an aircraft includes an innermost layer configured to contact the fuel, an outermost layer and a containment gel formed from isocyanate and polyol interposed between the innermost and outermost layers. The containment gel is configured to self-seal a ballistically formed hole therein, thereby reducing leakage of the fuel from the fuel cell.
