  • Publication number: 20250010557
    Abstract: Examples provide computer-implemented methods for forming a fiber-reinforced composite device comprising fiber-comprising tows. Methods include forming a first preform model having one or more anisotropic tow layup portions comprising fiber-comprising tows; receiving one or more mold geometrical components; receiving one or more molding force vector parameters; forming a n intermediate device model by deforming the first preform model against the mold geometrical components using the molding force vector parameters; and forming a second preform model. Forming the second preform model includes adjusting the first preform model by forming a tow layup adjustment vector comprising one or more vectors extending from one or more tow of the fist preform model to one of more tow of the second preform model as a function of one or more position transformation vectors extending from one or more tow of the first preform model to one or more tow of the intermediate device model.

  • Publication number: 20240001634
    Abstract: One example provides a process unit including a conveying device to convey a hybrid yarn comprising a plurality of fibers and a matrix through a channel bounded by a base body, and a cutting unit having a component configured as a sleeve mounted about the base body, the sleeve rotatable about the base body and including a circular recess at an axial end region which is eccentrically aligned with an axis of rotation of the sleeve, and a cutting element on a slide slidably mounted to the base body and disposed within the circular recess, wherein the slide rests on a support surface of the sleeve bounding the circular recess so that, due to the circular recess being eccentrically aligned with the axis of rotation, a rotational movement of the sleeve causes translational movement of the slide and the cutting element across the channel to cut the hybrid yarn.

  • Publication number: 20190224710
    Abstract: The invention relates to a glue gun (1), comprising: a housing (2), at least one storage means (5) for storing plastic, a heating device (11, 12), an outlet nozzle (10) for discharging the heated plastic from the glue gun (1), an extrusion unit (9) for shaping the strand (36) having plastic, which strand is to be extruded, a conveying device (17) for conveying the thermoplastic plastic from the storage means (6) to the heating device (11, 12) and through the outlet nozzle (10). The problem addressed by the invention is that it should be possible to store glue in the glue gun (1) even in large amounts and to join the parts to each other with a strand of fiber-reinforced plastic by means of adhesive bonds in such a way that the adhesive bonds withstand even large forces. This problem is solved in that the glue gun (1) comprises a pultrusion unit (8) for consolidating fibers and plastic.
