摘要： An article includes a hybrid nanocomposite product, which includes a nanostructure array and a resin matrix contained among and/or around the nanostructure array. The array/matrix is placed in between layers of dry or resin-infused fiber composite to permit formation of a composite structure. The nanostructure array and/or the resin matrix may be disposed in an abutting relationship with other layers of a composite. The array/matrix can provide reinforcement of the composite in the z-direction. Transfer of resin into dry fiber forms may be provided when the array/matrix acts as a resin transfer medium. Nanostructure arrays with a resin matrix can be prepared to form a resin film product. Methods are presented for infusing composites via resin-transfer molding (RTM), vacuum-assisted resin transfer molding (VARTM), resin film infusion (RFI), or injection molding wherein a resin matrix film substantially maintains alignment and position of the nanostructure array during the infusion process.

摘要： Methods for fabricating a ceramic matrix composite are disclosed. A fiber preform may be placed in a mold. An aqueous solution may be added to the fiber preform. The aqueous solution may include water, carbon nanotubes, and a binder. The preform may be frozen. Freezing the preform may cause the water to expand and separate fibers in the fiber preform. The carbon nanotubes may bond to the fibers. The preform may be freeze dried to remove the water. The preform may then be processed according to standard CMC process.

摘要： Methods of forming solid carbon products include disposing a plurality of nanotubes in a press, and applying heat to the plurality of carbon nanotubes to form the solid carbon product. Further processing may include sintering the solid carbon product to form a plurality of covalently bonded carbon nanotubes. The solid carbon product includes a plurality of voids between the carbon nanotubes having a median minimum dimension of less than about 100 nm. Some methods include compressing a material comprising carbon nanotubes, heating the compressed material in a non-reactive environment to form covalent bonds between adjacent carbon nanotubes to form a sintered solid carbon product, and cooling the sintered solid carbon product to a temperature at which carbon of the carbon nanotubes do not oxidize prior to removing the resulting solid carbon product for further processing, shipping, or use.

摘要： Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of novel ceramic composites. Additive manufacture or 3D printing of bulk ceramic and ceramic composite components occurs at considerably lower temperatures and shorter manufacturing intervals than the current state of the art. The methods, processes, systems, devices and apparatus and selection of precursor resins produce ceramic and ceramic composite material systems which have not been produced before by 3D printing.
