Multiaxials: Non-Crimp Fabrics
Innovative and tailor-made: SAERTEX composite reinforcements made of glass, carbon and aramid fibers. Those materials are also known as NCFs (non-crimp fabrics). We deliver non-crimp fabrics with more than 3,000 article designs. Depending on the fiber type, surface weight and angle combination, various mechanical characteristics can be achieved. SAERTEX multiaxials are individually configured for our customers and optimally adapted to a range of processes. Suitable methods are vacuum infusion, RTM, pultrusion, prepreg, compression, etc.
Benefits of SAERTEX multiaxial fabrics:
- Fiber, weight and orientation are ideally adjusted: The positions are specifically aligned to the ideal quantity and orientation in the loading direction // Angles of between -22.5° and +22.5° are possible // 0° position is also possible.
- Stretched fibers for optimum mechanical strength: Absorption of the highest possible loads through
stretched fibres // Reduced component weight while maintaining equal mechanical properties or even a higher component load with the same component weight.
- Individual drapability and outstanding permeability: The drapability of the SAERTEX multiaxials is tailored to customer requirements and exhibits outstanding permeability // Optimisation and enhancement of the SAERTEX fabrics for infusion processes.
- Cost savings due to fewer layers: Reduction of the manufacturing costs (fewer layers are required thanks to the higher area weight of the individual layers).
- Resin compatibility: SAERTEX non-crimp fabrics are optionally compatible with various resin systems: EP / UP / VE / PUR / PP / PA and caprolactam.
In comparison with crimped fibers, as found in woven textiles for instance, straight lay-up (non-crimp) fibers have the greatest possible load-bearing capacity. Composite components manufactured from non-crimp fabrics (NCFs) permit the ideal transmission to the component of the generated forces – in the direction of loading – by specifically adjusting the fibre orientation.
In comparison with standard reinforcement textiles this delivers either reduced component weight for identical mechanical characteristic values, or a higher component loading for the same component weight.
