Method for producing a multilayer fiber composite preform for a fiber composite component

A method produces a fiber composite preform for a fiber composite component. The fiber composite preform has a plurality of layers of a fiber roving. The method includes: providing a support core for arranging the fiber roving s on a braiding device, the support core having a support core longitudinal axis, producing a first braided fabric layer from fiber rovings on the support core in a first braiding direction parallel to the support core longitudinal axis of the support core by the braiding device, and producing a second braided fabric layer from fiber rovings on the first braided fabric layer by the braiding device. The second braided fabric layer is produced in a second braiding direction parallel to the support core longitudinal axis, the second braiding direction being opposite the first braiding direction.

Braiding apparatus capable of generating a two-point interweaving operation
11566355 · 2023-01-31 ·

A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes. The strand carriers shuttle on both braiding routes respectively and incessantly. Two intersection points are defined when the two braiding routes intersect. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the two intersection points during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has two crossing points, which increases the practicability of the rope.
