Abstract: A method for manufacturing at least one of fibers and yarn from natural fibers includes providing at least one of technical fibers, elementary fibers, meso fibrils, and micro fibrils. Greater than or equal to 80% of the at least one of the technical fibers, the elementary fibers, the meso fibrils, and the micro fibrils are short natural fibers having a length that is less than or equal to 12.7 mm. The method includes creating at least one of a dispersion, a gel, a solution, a paste, and a dough including the at least one of the technical fibers, the elementary fibers, the meso fibrils and the micro fibrils; and spinning filaments of the at least one of fibers and yarn using the at least one of the dispersion, the gel, the solution, the paste, and the dough.

Abstract: A battery pack for a vehicle includes a housing including at least one pack vent between an interior and an exterior of the housing. A plurality of battery cells are contained within the housing. A channel tray includes channel arrays having a plurality of vent openings each positioned in connection with a vent on each of the plurality of battery cells. The channel arrays are in connection with the at least one vent of the housing, wherein the channel system is enclosed from the rest of the volume of the pack and the plurality of vent openings are each provided with a vent cover.

Abstract: A method for creating a fiber includes obtaining constituent natural fiber components by breaking down at least one of fresh natural fibers, fibers extracted after post-industrial use, fibers extracted after post-consumer use, and combinations thereof. The constituent natural fiber components comprise at least one material selected from a group consisting of cellulose, pectin, hemicellulose, lignin, and wax. The method includes separating the constituent natural fiber components into N natural fiber precursors, where N is an integer greater than one; creating a mixture of the N natural fiber precursors using a predetermined ratio of the N natural fiber precursors; and creating at least one of fiber and yarn using the mixture.
