摘要： Methods for enhancing the strength and stiffness of fibers, including nanoreinforced fibers and fiber tows, composite materials including the nanoreinforced fibers and tows, and articles of manufacture including the composite materials, are disclosed. The methods involve adhering random or aligned nanoreinforcement materials, such as carbon nanotubes, nanofibers, graphene plates, nanowires, nanoparticles, into or onto a spread carbon tow or yarn to form modified fibers wherein nanoreinforcement is adhered or trapped within the carbon tow. The carbon nanotubes or nanofibers can be aligned. Carbon fiber tows including the modified carbon fibers can be processed or woven for impregnation with a thermoset resin or thermoplastic to form a composite structure. The performance increase of the modified fibers relative to the unmodified fibers can be greater than the weight increase caused by the modification. Increased fiber stiffness and strength can result in a significant weight saving.

摘要： Surface films, paints, or primers can be used in preparing aircraft structural composites that may be exposed to lightning strikes. Methods for making and using these films, paints or primers are also disclosed. The surface film. can include a thermoset resin or polymer, e.g., an epoxy resin and/or a thermoplastic polymer, which can be cured, bonded, or painted on the composite structure. Low- density electrically conductive nanoparticles are disclosed, such as carbon nanofiber, copper powder, metal coated microspheres, metal -coated carbon nanotubes, single wall carbon nanotubes, graphite nanoplatelets and the like, that are uniformly dispersed throughout or on the film. Low density conductive materials can include metal screens, optionally in combination with carbon nanofibers.

摘要： Systems and methods for lightning strike materials are disclosed. The material may include a carbon fiber tow (110). Carbon nanotubes may be grown on carbon fibers (112;122) within the carbon fiber tow (110). The carbon nanotubes may cause the carbon fibers (112;122) to separate, decreasing a carbon tow fiber volume fraction of the tow (110). The growth of the carbon nanotubes may be controlled to select a tow fiber volume fraction of the tow (110). The lightning strike material may transmit electricity to decrease damage to the composite structure in case of a lightning strike.
