摘要： A method for making highly finished surface parts of an advanced composite material comprises the step of coupling a fibrous base material layer with a further layer impregnated by a resin system identical to or compatible with that used for making the part, and directly crosslinking the part made of the advanced composite material. The method is used for making motor vehicle body parts starting from a composite material, but can also be used in the nautical, sports and aeronautical fields. The method according to the present invention reduces or completely eliminates a visibility of reinforcement fibers on the surface of the article of manufacture thus made.

摘要： The present invention relates to a method and a device for producing a fibre composite component and to a fibre composite component. The method has the steps of: a) preparing a long-fibre layer (2); b) applying short fibres (9) to the long-fibre layer (2); and c) applying a further long-fibre layer (2) to the long-fibre layer (2) provided with the short fibres (9). The device is configured to carry out the method. The fibre composite component according to the invention has a layer arrangement (15) composed of at least two long-fibre layers (2), wherein the layer arrangement (15) has an addition (16) of short fibres (9). Preferably, the short fibres (9) are configured and dimensioned and are applied in such a way or are in such an arrangement that propagation of tears in one of the long-fibre layers (2) into in each case the other or an adjacent one of the long-fibre layers (2) and/or delamination between the long-fibre layers (2) is rendered more difficult.

摘要： 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.
