Redefining Multiaxial Non-Crimp Fabric (NCF) Reinforcements

Multiaxial reinforcements are fabrics composed of two or

more plies, or layers of unidirectional fibers, the optimal

reinforcement configuration.

Each individual layer can be oriented in a different axis and for

this reason the fabric construction or assembly is referred to as

‘multi-axial’.

Depending on the number of layers and varying orientation and

axis, a unidirectional, bi-axial, tri-axial and quadri-axial architecture

can be assembled into one Non-Crimp Fabric system.

The various layers are held together with a stitched

thermoplastic (TP) yarn - typically polyester - which prevents

crimping or undulations that can lead to loss of performance in

the finished laminate. The stitching also enables easier handling as

the fabric remains intact even when cut.

Straight, non-crimped fibers within a multiaxial fabric system

allow very good resin impregnation and wet-out, perfect for

Infusion and all Closed Molding processes. The stitching helps the

diffusion of resin vertically through the layers (Z direction),

thereby optimizing infusion rates.

characteristics

Designed for applicationsrequiring a high concentrationof reinforcement in only onedirection by placing continuousfibers in either a 0° or 90° axis.

Fibers are held in place byeither interweaving alightweight hot melt yarn tolock the unidirectional fibers inplace, or by stitching the fibersin place using a stitch yarn.

The input fibers are designedto give controlled wet-out andexcellent laminate properties.

end-Use Application

Great for demandingapplications with a high aspectratio (length to width ratio)such as wind blades, poles, and stringers and are alsocommonly used in FRP pipeand fittings for increasedstrength.

Useful in applications where a discrete area requiresadditional strength or stiffness.

Wrapping of existing structuralcomponents, such as columnsand beams with UnidirectionalFabrics could also greatlyincrease the lifespan andperformance of these criticalload-bearing members.
