Abstract: Aluminum-boron nitride nanotube composites and methods of making thereof are disclosed herein. In at least one specific embodiment, the method can include: at least partially coating boron nitride nanotubes with aluminum to make an aluminum-boron nitride nanotube layered structure, where the at least partially coating is performed by sputter deposition, and where the boron nitride nanotubes have a length of about 100 ?m to about 300 ?m; sintering the aluminum-boron nitride nanotube layered structure to make an aluminum-boron nitride nanotube pellet, where the sintering is performed by spark plasma sintering; and rolling the aluminum-boron nitride nanotube pellet to make the aluminum-boron nitride nanotube composite.

Abstract: Boron nitride nanotube (BNNT)-magnesium (Mg) alloy composites and methods of fabricating the same are provided. The BNNT-Mg alloy composites can have a sandwich structure and can be fabricated by high-pressure spark plasma sintering. A mat of BNNTs can be sputter-coated with Mg, and then sandwiched between Mg alloy particles, followed by a sintering step. The BNNTs can include a hexagonal boron nitride phase.

Abstract: A shape-memory epoxy polymer graphene foam composite (SMEP-GrF) is formed from an open cell graphene foam (GrF) surrounded by and infiltrated with a shape-memory epoxy polymer (SMEP) matrix, with the GrF being an intra-connected framework within the SMEP matrix. The SMEP-GrF provides self-healing properties to a device fabricated from the SMEP-GrF. The SMEP-GrF is formed by infusion of an epoxy resin and hardener in an open cell GrF and curing the infused GrF.

Abstract: A graphene foam ceramic composite (GrF-CC) comprises an open cell graphene foam (GrF) surrounded by and infiltrated with a sintered low temperature co-fired ceramic (LTCC) matrix. The GrF-CC can be prepared by infiltrating an open cell GrF with an LTCC slurry, removing the solvent from the slurry with solidification to a ceramic-GrF green body, and sintering the ceramic-GrF green body to form the GrF-CC. Sintering by spark plasma sintering (SPS) allows an LTCC GrF-CC that has a density of at least 90%.

Abstract: Metal-nanoparticle composites, such as metal-boron nitride nanoparticle composites, and methods of manufacturing the same are provided. Ultrasonic casting techniques can be used to achieve uniform dispersion of nanoparticles, such as boron nitride nanotubes (BNNTs) in a metal matrix, such as aluminum. The BNNTs can be incorporated into the melt of the metal, and ultrasonic treatment can then be applied.
