Process of debundling carbon fiber tow and molding compositions containing such fibers
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.
Fibre-reinforced components
A method for forming a composite component, comprising: locating a rigid composite element comprising a matrix interspersed with long fibre reinforcement in a mould that is shaped to define a cavity about the rigid element; loading a material comprising a matrix precursor interspersed with short fibre reinforcement into the cavity; and curing the matrix precursor.
Or relating to three dimensional mouldings
The invention relates to a blank for compression moulding a part in a compression mould comprising one or more moulding recesses, said blank comprising a body formed from a first moulding compound comprising a fibrous reinforcement material and a thermo-curable resin material, and a region located on the surface of the body formed from a second moulding compound; said second moulding compound comprising a fibrous reinforcement material and a thermo-curable resin material, and exhibiting increased flow at one or more temperatures between 20° C. and the cured Tg of the first moulding compound compared to the flow of the first moulding compound at the same temperature.

COMPOSITE COMPONENT AND METHOD FOR PRODUCTION THEREOF
The present disclosed subject matter relates to a method for producing a composite component, in particular for a gliding board, roller board or skateboard. The method comprises introducing a bottom mat made of reinforcing fibers, above this a flat core made of plastic, and above this a top mat made of reinforcing fibers into an opened mold, closing the mold, introducing an uncured plastics matrix into the closed mold, allowing the plastics matrix to cure in the closed mold, opening the mold, and demolding the composite component. The core is provided on its lower and upper sides with a plurality of spacer nubs, which keep the bottom and top mats in the closed mold at a distance from the lower and upper sides.
