Provided is an electrically activated shape memory polymer composite capable of thermal shape reformation using electric power to heat the composite through its matrix glass transition temperature. The composite includes an adaptable polymer matrix component using a diglycidyl ether resin, at least one substantially well-dispersed conductive or magnetic nano-filler component, and at least one elastic, laminated layer. Also provided are methods of preparing the composite and methods of activating the composite. A shape reformation of the composite is triggered by applying an electric field at DC and/or at a frequency above about 1 μHz for a sufficient time.

A metallized film capacitor includes: a metallized film columnar body including two metallized films that are laminated and wound, the two metalized films each including a vapor-deposited metal film with a plurality of vapor-deposition-free slits and fuse portions each interposed between the vapor-deposition-free slits, and a polyvinylidene fluoride dielectric film, the metallized film columnar body having two electrode extraction surfaces; metal-sprayed parts disposed respectively on the two electrode extraction surfaces: and outgoing terminals joined respectively to the metal-sprayed parts. Each of the two metallized films has a shape with successive sloped ridges and valleys in a cross-section orthogonal to a winding direction, and the two metallized films are laminated such that the ridges and valleys of one of the metallized films are aligned with the ridges and valleys of the other one of the metallized films.

Fabrics made for apparel, tents, sleeping bags and the like, in various composites, constructed such that a combination of substrate layers and insulation layers is configured to provide improved thermal insulation. The fabric composites are constructed to form a radiant barrier against heat loss via radiation and via conduction from a body.

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.

A composite ballistic panel provides cost-effective ballistic protection against projectiles. The composite ballistic panel comprises a composite ballistic assembly with an impact/strip layer that alters the projectile during striking contact with the projectile by flattening the projectile, distorting the shape of the projectile, reducing rotation of the projectile, reducing the velocity of the projectile, and inducing yaw to the projectile; a non-ballistic deflection layer that forms a cavity to inhibit propagation of the projectile's shock wave; and a containment layer that stops and captures the projectile within the composite ballistic assembly. Additionally, the composite ballistic panel may have a protection layer and a boundary edge to enhance capture of the projectile and ballistic characteristics, and an intermediate layer that acts as spacer between layers.

Various embodiments provide multi-layered self-healing materials, capable of repairing puncture damage. The multi-layered self-healing materials, capable of repairing puncture damage of the various embodiments may be constructed by sandwiching a reactive (e.g., oxygen sensitive) liquid monomer formulation between two solid polymer panels, such as a polymer panel of Barex 210 IN (PBG) serving as the front layer panel and a polymer panel of Surlyn® 8940 serving as the back layer panel. The various embodiments may provide methods to produce multi-layered healing polymer systems. The various embodiments may provide a two-tier, self-healing material system that provides a non-intrusive capability to mitigate mid to high velocity impact damage in structures.

A method for the design and development of new ballistic resistant articles is provided. Improved ballistic articles are formed of polyethylene-based composite laminated structures having unique material properties including material density, Poisson's ratio, and modulus of elasticity (Young's modulus). Cycle time for completing design and development is less than 30 calendar days.

A thermoplastic multilayer article comprises: a polycarbonate substrate comprising a polycarbonate composition comprising at least one of a polycarbonate homopolymer, a copolycarbonate, or a polycarbonate copolymer, the polycarbonate substrate having a first surface and an opposing second surface; and a first polyurethane layer laminated or coextruded on at least a portion of the first surface of the polycarbonate substrate, the first polyurethane layer comprising a first aliphatic thermoplastic polyurethane and a polyurethane UV stabilizer, wherein the first aliphatic thermoplastic polyurethane comprises first segments formed via a reaction of caprolactone and an aliphatic isocyanate, and second segments formed via a reaction of a chain extender and the aliphatic isocyanate.

The present disclosure relates to a color wrapping film for a vehicle, which has an excellent impact resistance and excellent scratch restorability due to a base layer and a coating layer formed of a polyurethane-based material, and suppresses discoloration caused by an external environment by adding a color pigment to a separate layer.

A method is disclosed for producing a polyurethane film including the steps of depositing a prepolymer composition, drying the prepolymer composition, and crosslinking the propolymer composition.
