OVERBRAIDING

Preforms made by the Overbraiding technique:
Overbraiding is the technique used to produce net shape cost-effective structural preforms, during the overbraiding, the braid is placed directly onto a core, which have the inner geometry of the desired preform. By reciprocating the core through the braiding point, a pre-selected number of layers can be braided to obtain the desired wall thickness / aerial weight. The lightweight core can remain in the product or a lost core technique can be used for the production of a hollow product.

Benefits of Overbraiding:

Cost effective method and low waste rates (5-10%)
Reproducible due to computer control and automated processes
Time saving compared to building your own preforms manually
Braiding angles are programmable from 150 to 800
0° (UD) yarns can be integrated to form a tri-axial braid
The ratio between bias and UD can vary from 100/0 up to 15/85
Hybrids are possible in the bias and in the UD direction
Excellent energy absorption in crash structures. Braided structures act as crackstoppers
Braided structures have a good resin permeability
Eccentric products are possible, even banana shaped preforms
Preforms injected with the RTM process can have a fibre volume fraction of 55%

What we offer:
For each product an overbraiding machine and yarn configuration can be selected to produce your optimum preform. We have 11 years of experience in overbraiding and we are able,with our R & D team, do the total preform development at Eurocarbon. When a special braiding machine or extra equipment is needed, we can build it and we can offer a turn-key solution and transfer of know-how, so you can produce your own preforms. Preform developments and preform production can be done entirely in house
