Multiaxial Carbon Fabric

What are carbon non-crimp fabrics and how can discounted variants be used?

Carbon fabrics are non-woven reinforcement textiles in which carbon fibers are arranged in specific orientations – such as unidirectional, bidiagonal, or bidirectional – and lie parallel without interlacing. This fiber alignment allows for targeted adaptation to load-bearing structures, such as in lightweight composite components. The discounted items offered here consist of B-grade stock, overruns, or surplus batches that may deviate from standard quality – for example, due to visual imperfections. In many cases, the technical properties remain usable, but their suitability for high-stress or safety-critical applications should be assessed carefully. For prototyping, development work, or model construction, these fabrics can offer an economical and practical alternative.

What are the characteristics of b-grade carbon non-crimp fabrics?

The mechanical performance of carbon fabrics is based on the oriented fiber layout, which – when defect-free – enables high strength and stiffness. In the case of B-grade materials, variations from standard values may occur and should be taken into account, especially in certified applications. The key advantage lies in the significantly reduced cost, sometimes up to 70% less than comparable new stock. For applications with lower demands on optical appearance or dimensional accuracy, these fabrics remain technically viable. Available configurations include unidirectional, bidiagonal, and bidirectional variants. In addition to carbon fabrics, our portfolio includes hybrid fabrics, aramid fabrics, E-glass rovings, and carbon fabric specials at reduced prices.

What are the differences between unidirectional, bidiagonal, and bidirectional layouts?

The fiber orientation plays a crucial role in defining the mechanical properties of composite parts. Unidirectional carbon fabrics offer reinforcement in a single load direction and are ideal where linear loads dominate. Bidiagonal fabrics, with fibers oriented at angled directions, are suited for shear-stressed components. Bidirectional variants, with 0° and 90° fiber orientations, provide balanced in-plane performance. These fabric types are also available as discounted stock, though the fiber volume or layer structure may vary from standardized materials. It is therefore essential to evaluate use case requirements and check each product description carefully.

In which areas are carbon fabric specials suitable?

Even though B-grade items or surplus stock may not deliver the full performance of certified new materials, they present an opportunity for cost-effective applications with moderate requirements. In research, development, model building, and non-critical structural components in mechanical engineering or marine construction, these materials are often well suited. They also contribute to resource efficiency and reduce industrial surplus. The carbon fabric specials offered in our shop include a variety of non-crimp fabric types, from unidirectional carbon fiber composites to bidiagonal and bidirectional structures, frequently with a significant price advantage over regular warehouse stock. A technical assessment by experienced users is recommended during processing.
