CARBOWEAVE® UMS – ultra-lightweight biaxial carbon non-crimp fabric made from high-modulus Tenax® UMS40 fibre for exceptionally thin, high-stiffness CFRP laminates.
Available in STANDARD (+/−45°) and MIRRORED (−/+45°) versions for controlled, symmetrical laminate lay-ups.
The two unidirectional carbon fibre plies are held together by an epoxy-compatible binder. Uniform fibre distribution and nearly crimp-free alignment allow efficient use of the high fibre stiffness. Compared with conventional non-crimp fabrics featuring a supporting scrim, CARBOWEAVE® offers improved drapability and surface quality.

Benefits and laminate lay-up
The ±45° fibre orientation is particularly suitable for torsionally loaded components. Torsional reinforcement plies can be laid up without diagonal cutting and the associated material waste.
In very thin laminates, unsuitable stacking sequences may cause distortion. The fabric is therefore available in two mirrored configurations:
- STANDARD (+/−45°), item no. 192029060-CBA-3
- MIRRORED (−/+45°), item no. 192029060-ABC-3
The mirrored version reverses the sequence of the two fibre plies. Combining both versions allows symmetrical stacking sequences to be achieved as required. This can help reduce unwanted distortion and improve dimensional stability, particularly in very thin components.
Typical applications
- Model aircraft wings, tailplanes and trailing edges
- Thin-walled CFRP shells and lightweight structures
- Torsional reinforcement of wings and fuselages
- Lightweight motorsport and sports equipment components
- Weight-optimised components in boatbuilding and marine applications
Comparison of Tenax® carbon fibres
UMS40 offers the highest tensile modulus of the three fibre types compared. IMS65 provides the highest tensile strength and elongation at break, while HTS40 is suitable for robust general-purpose applications.
