20g Carbon Fiber Surface Mat

The 20g Carbon Fiber Surface Mat is a nonwoven reinforcement material made from chopped carbon fiber. With an areal weight of 20 g/m², it is designed primarily as a thin surface layer for composite laminates. The random fiber structure can conform to curved and irregular mold surfaces and helps reduce the visible texture of woven reinforcement beneath the surface.

Unlike woven carbon fiber fabric, the fibers in the mat are not arranged in a fixed warp-and-weft pattern. This makes the material suitable for applications where surface coverage, conformability and a thin carbon fiber layer are required.

Product Specifications

Material and Production Process

The material is produced from chopped carbon fiber through a wet forming process. The fibers are dispersed before forming to achieve a relatively even distribution, after which the fiber web is formed into a nonwoven mat.

The resulting mat has no woven yarn structure, allowing the fibers to orient in multiple directions within the surface layer. Final composite performance depends on factors including resin type, fiber content, laminate construction and molding conditions.

Surface Layer Characteristics

The 20g Carbon Fiber Surface Mat provides a thin carbon fiber layer for composite laminates. Its nonwoven structure can conform to curved surfaces and helps cover the texture of woven or other reinforcement layers underneath after resin impregnation.

This makes it relevant to CFRP parts where the appearance and uniformity of the molded surface need to be considered together with the underlying reinforcement structure. The actual surface result depends on resin impregnation, mold condition, curing and any subsequent finishing process.

Functional Composite Applications

Beyond surface applications, carbon fiber can contribute electrical and thermal conductivity to a composite system. For this reason, carbon fiber surface mats may be incorporated into selected conductive composite components, electronic housings, electrostatic-control structures and electromagnetic shielding designs.

The material can also be considered for selected industrial composite products such as pipes, tanks, containers and filtration components. For functional applications, electrical, thermal or shielding performance should be evaluated on the finished laminate rather than based on the surface mat alone.

Available Sizes and Customization

The standard width is 1 m or 1.25 m, with a standard areal weight of 20 g/m².

Yuruis can discuss customized specifications for different composite production requirements. Customers can provide the required weight, width, roll size and application when requesting a quotation.

For new applications, sample testing can be arranged before bulk production so that the material can be evaluated with the customer's resin system and processing method.
