    Abstract: Methods and apparatuses for continuous, large scale, commercially viable production of nanoforests. A roll-to-roll process passes a flexible substrate, including fibers and fabrics, through a furnace. Precursors are introduced in a growth zone in which a vertical or horizontal nanoforest of nanotubes or nanowires is grown on the substrate. Sensors and actuators with feedback control are provided for parameters such as substrate speed, substrate tension, furnace temperature, precursor flow rate, nanoforest thickness, and nanoforest. The furnace is preferably enclosed for environmental and safety purposes. The feed roll and take-up roll are disposed in housings can be attached to the furnace via airlocks, which enables rapid loading and unloading of the rolls using techniques well known in the industry while maintaining furnace conditions. The furnace can encompass flattening rollers and a second growth zone to enable manufacture of orthogonal nanoforests comprising a vertical nanoforest grown on a horizontal nanoforest.

    Abstract: A reinforcement for increasing the strength and toughness and other properties in both transverse and in-piano directions for a composite material, and methods of manufacture therefor. The reinforcement has a layer of a nanoforost of vertical nanotubes or nanowires and a layer of horizontal nanotubes or nanowires. The reinforcement can be made by rolling a vertical nanoforest to produce a collapsed layer of horizontal nanofubes or nanowires, then growing a vertical nanoforest on the collapsed layer. The reinforcement can be grown directly on fibers which are used to reinforce the composite material, or alternatively Interleaved with layers of those fibers before the composite part is cured. The reinforcement and manufacturing method are compatible with almost any composite material in any shape, including epoxy, polymer, or ceramic matrix composites, or any manufacturing method, including prepreg, wet-layup and matrix film stacking. The present invention reduces scrap, rework, and repair hours for composites manufacturing.
