Abstract: A process for debundling a carbon fiber tow into dispersed chopped carbon fibers suitable for usage in molding composition formulations is provided. A carbon fiber tow is fed into a die having fluid flow openings, through which a fluid impinges upon the side of the tow to expand the tow cross sectional area. The expanded cross sectional area tow extends from the die into the path of a conventional fiber chopping apparatus to form chopped carbon fibers, or through contacting tines of a mechanical debundler. Through adjustment of the relative position of fluid flow openings relative to a die bore through which fiber tow passes, the nature of the fluid impinging on the tow, the shape of the bore, in combinations thereof, an improved chopped carbon fiber dispersion is achieved. The chopped carbon fiber obtained is then available to be dispersed in molding composition formulations prior to formulation cure.

Abstract: A system for spreading a multi-filament bundle of fibers such that most of the individual fibers are exposed for various treatment and coating processes is described. The system is particularly suited to, but not limited to, carbon fiber applications. In such applications it is desired to spread carbon fiber tows consisting of anywhere from less than 1,000 to in excess of 144,000 individual filaments such that a significant portion of the filaments are exposed for processing. A spreading system can consist of one or more individual spreaders placed in series to achieve a desired spread. Each spreader consists of expandable bands, an expandable tube, or a compressible and expandable piece of foam placed between two angled support discs. The discs are angled away from each other such that the bands, tube, or foam between the closest points of the angled discs will stretch or expand as the support discs rotate about their respective axes. The fiber bundle enters the spreader at the point where the discs are closest together and exits at the point where the discs are furthest apart. The bands, tube, or foam therefore support the incoming fiber bundle and stretch or expand to an established width, thereby separating a portion of the individual filaments. Changing the angle of the support discs can control the amount of stretch. As the angle is increased, the overall stretch or expansion that the bands, tube, or foam are subjected to will increase, thereby increasing the filament separation of the fiber bundle. One or more spreaders can be placed in series to obtain a desired spread beyond the capabilities of a single spreader. The spreaders can be free spinning or motor driven depending upon the application.

Abstract: A fiber spreading apparatus prevents a fiber bundle from being split apart. Position restriction rollers 43g and 43h are arranged in a fiber bundle streaming and feeding section 43 so as to restrict a streaming and feeding position of the fiber bundle 1. A spread width of the fiber bundle 1 is thereby restricted and the fiber bundle is prevented from being split apart. A squeezing roller mechanism 52, which is arranged outside of a liquid stored in a fiber spreading tank 40, guides the fiber bundle 1 from within the liquid in the fiber spreading tank 40 to the squeezing roller mechanism 52 while bringing the fiber bundle into constant contact with a first guide 51. By so configuring, a surface tension of the liquid acts to prevent the fiber bundle 1 from being split apart.

Abstract: A method for the production of a multifilament carbon fibre-based longitudinal reinforcing element, designed to be incorporated in a rubber-based item. Said method comprises the following steps, whereby untwisted carbon fibres are plunged into an impregnating bath contained a solution of resorcinol-formaldehyde resin and rubber latex, the impregnated fibres are then dried and the dried fibres are subsequently twisted. The inventive method is characterised by the fact that it also comprises a step, during the impregnation step, consisting in opening out the carbon fibres by spreading out the constituent filaments thereof in such a way that each fibre has an increased surface area on which the impregnation can be performed.
