The ultra-lightweight carbon fibre veil (8 g/m²) improves the surface quality of high-performance composite components. It reduces print-through and pinholes, promotes uniform resin distribution and can significantly reduce finishing work. Suitable for epoxy, polyester and vinyl ester resin systems.
Description
The 8 g/m² carbon fibre veil has been developed specifically for high-quality composite surfaces. As an ultra-light surface layer, it creates a smooth, resin-rich finish and enhances the appearance of composite laminates.
The uniform distribution of the short carbon fibres helps reduce print-through of the underlying reinforcement, minimises pinholes and other surface imperfections, and can significantly reduce sanding, filling and polishing operations.
With an areal weight of only 8 g/m², the veil adds virtually no weight to the laminate and is therefore ideal for lightweight composite applications. Thanks to the conductive properties of carbon fibres, it can also be used to produce electrically conductive or electrostatic dissipative surface layers.
Benefits
The carbon fibre veil improves laminate surface quality, promotes uniform resin distribution and reduces common surface defects such as print-through and pinholes. As a result, finishing work can often be significantly reduced without noticeably increasing laminate weight.
Typical Applications
Typical applications include automotive engineering, motorsport, aerospace, tool and mould making, mechanical engineering and model making. It is also suitable for exposed carbon fibre components and for electrically conductive or electrostatic dissipative surface layers.
Processing
The veil is applied as the surface layer and fully impregnated with the selected resin system. The structural reinforcement layers are then applied.
Suitable for the following composite manufacturing processes:
- Hand lay-up
- Vacuum infusion
- RTM (Resin Transfer Moulding)
- Filament winding
- Pultrusion
- Compression moulding (subject to material and process compatibility)
Uniform and complete resin impregnation is essential for optimum surface quality. Preliminary trials are recommended.

Technical Notes
The carbon fibre veil is designed as a surface and functional layer and is not intended to provide structural reinforcement. It should always be used together with suitable reinforcement fabrics or unidirectional materials.
The specified surface resistance was measured under defined test conditions. The electrical properties of the finished laminate depend on the resin system, laminate design and electrical contacting.
