Carbon multiaxial fabric

Carbon multiaxial reinforcements are fabrics that consist of two or more plies or layers of parallel oriented carbon yarns or rovings, showing a perfect reinforcement configuration. Each individual layer can be oriented in a different axis and for this reason the fabric construction is called ‘multi-axial’. Depending on the number of layers and varying orientation and axis, a unidirectional (UD), bi-axial (Biax), tri-axial and quadri-axial assembly can be made into a Non-Crimp Fabric (NCF) 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. This ensures the highest values for strength and stiffness.

The stitching also enables easier handling as the fabric remains intact even when cut. The straight, non-crimped carbon 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 (in Z direction).

Carbon multiaxial reinforcements are used where the highest tensile, flexural and compression strength and minimal print-through is needed.

The multiaxial fabric is suitable for all normal processes like hand lay-up, RTM, Pultrusion, Infusion and Vacuum.

Typical end-uses: aerospace, military, constructional parts, medical applications, Marine, sports goods and automotive.

carbon bi-axial fabric

Bi-axial carbon fabrics (Non Crimp Fabrics) have two plies of parallel fibers that are stitchbonded in an angle of + 45 and - 45 degrees. They are available in a weight range of 100 to 600 g/m2, all in a width of 127 cm. Due to the non-crimped fiber orientation these kind of reinforcements show optimum tensile and flexural properties in the finished laminate.

Biax fabrics are suitable for typical processes like hand lay-up, RTM and Infusion. The fabrics have excellent conformability and quick wet-out to help you build up thickness which saves time. Thanks to the stitching yarn that prevents unraveling you can easily cut the fabric into tapes.

Typical end-uses: vehicle panels, seats, Marine structures, carbon fibre molds, inner layers for flat sheets.
