Braiding is a key pre-forming technology for producing low-cost, high-volume composites and is ideal for mixed-material systems and rapid, limited production runs. Braids are used extensively in applications like automotive, infrastructure, engineered materials, marine, fashion and textiles. Braiding machines interlace yarns through the use of bobbin spindles, ratcheting mechanisms, compression springs and eyelets. The geometry of the carriers and clearance between yarns is important to prevent entanglement during braiding. Braiding has been used for millennia and is well-suited for automated production and integrating features into composites without cutting fibers.

Braiding has been identified as one of the
key pre-forming technologies for
producing low cost high volume
composites. Braiding
is ideal for mixed material systems and
rapid and limited production runs. Braids
are used extensively in a multitude of
industrial applications, including
automotive, civil infrastructure,
engineered composite materials, marine,
fashion, and textiles.

5. The primary
components
include bobbin
spindle,
ratcheting
mechanism,
compression
springs, and
eyelets.

8. When the bobbin
carriers are parallel to
the machine axis, a
significant amount of
intra-yarn interaction
occurs, which can
prevent the formed
fabric from pulling up
tightly in the braid
formation region.

10. This machine
produces a
narrow fabric
similar to braids
produced by
plaiting of hair.
It employ two
horn gears and a
Figure-eight track
plate to interlace
the yarns

11. The repeating
pattern is
determined by
which carriers
are utilized
during the
braiding
operation.

12. During the braiding process,
the yarns must have
suitable clearance with
adjacent bobbin carriers’
eyelets to prevent
entanglement.
Clearance can be
accomplished naturally by
geometry, i.e. yarns form a
cone with the braid point,
or artificially with the use of
a forming ring.

13. Conclusion
Braiding has been practiced for millennia and
its use presently widespread. The interlacing
structure of the yarns can be described by a
braid pattern. The choice of the braid
pattern depends on requirements
Braiding is suited for automated series
production and integration of product
features such as holes and flanges without
fiber cutting
