Triaxial weave spread tow carbon fiber / Kevlar fabric, 170g/m2
Product code: TXD-20-T700-120-K29-50
This carbon/Kevlar fabric has been designed to produce lightweight quasi-isotropic laminates in a single layer.
- It is woven from Toray T700 high strength carbon fibers and KevlarTM 29 aramid fibers which are extensively used in body/vehicle armor applications. One side of this fabric has a wasp/hornet style with both carbon and Kevlar fibers visible, the other side is dark.
- Its dense triaxial weave has a high resistance to tensile, compressive and shear stresses in every in-plane direction as well as a high impact strength. As fibers run along three directions intersecting at 60 degree angles, a laminate produced with this fabric has a triangular structure that is very stable. The triaxial weave can also provide a composite part with both longitudinal and torsional resistance. Combined with the use of spread tows, this triaxial weave provides the fabric with the mechanical qualities of a [0/+60/-60] quasi-isotropic laminate: its stiffness is independant of the angle of rotation.

- Spread tows provide the fabric with greater stiffness and strength in compression. Carbon and aramid fibers are spread into 20 mm/0.79 in. wide, 60 µm/2.36E-3 in. thick tapes. The resulting fabric has practically straight fibers which are better suited to resist buckling. This makes the laminate more resistant to compressive stress. Moreover, due to their low crimp rate, spread tow fabrics also enable a higher fiber-to-resin volume ratio compared with traditional reinforcement fabrics.
- No additional tape binder is present. Although the fabric can be delicate to manipulate, this ensures excellent impregnation properties and high fiber-to-matrix adhesion.
Possible processing methods:
Applications for this triaxial fabric include carbon/Kevlar sheets and panels, surfboard/snowboard outer layers, kayak hulls, airplane model wings etc.
This fabric is supplied on a kraft paper for ease of manipulation, wraped around a cardboard tube, protected by a polyethylene film against humidity and by a bubble wrap. For optimal conservation, storing should take place in dry conditions and below 30°C.
