Overbraiding
At Eurocarbon, we provide expert overbraiding consultancy and custom solutions for composite performances. By combining our expertise with state-of-the-art overbraiding machine equipment, we enable efficient, repeatable, and cost-effective production of structural preforms. Whether you are looking for in-house preform development, equipment design or a turnkey manufacturing setup, our team is ready to support your project from concept to completion.
Preforms Made By the Overbraiding Technique
Overbraiding is a technique used to produce net-shape, cost-effective structural preforms. In overbraiding, fibers are braided directly onto a core, which defines the internal geometry of the desired shape. By reciprocating the core through the braiding point, multiple layers can be applied to achieve the desired wall thickness or areal weight. The lightweight core may either remain inside the final product or be removed using a lost-core technique to create a hollow structure.
Benefits of Overbraiding
- Cost-effective method with low waste rates (typically 5–10%)
- Reproducible results thanks to CNC control and automated processes
- Timesaving compared to manual preform construction
- Braiding angles are programmable between 15° and 80°
- 0° (UD) yarns can be integrated to form a triaxial braid, ideal for handling bending and torsion
- The ratio between bias and UD yarns can range from 100/0 to 15/85
- Hybrid configurations possible in both bias and UD directions
- Excellent energy absorption in crash structures—braided designs function as natural crack stoppers
- Good resin permeability for efficient infusion
- Eccentric geometries possible, including banana-shaped preforms
- Preforms can be used with RTM processes to achieve fiber volume fractions up to 55%
What We Offer
For each project, we carefully select the ideal combination of overbraiding machine equipment and yarn configuration to create the optimal performance for your application. Since 1994, our experience in overbraiding consultancy has enabled us to conduct complete in-house preform development in collaboration with our dedicated R&D team. When required, we also design and build custom braiding machines or auxiliary equipment tailored to your specific needs. As part of our turnkey approach, we offer full technology transfer, allowing you to implement your own overbraiding machine equipment and begin in-house production with confidence. From concept to final production, all stages of perform design, testing, and manufacturing can be managed seamlessly under one roof at Eurocarbon and our sister company, Eurobraider.
