10g Carbon Fiber Surface Mat

10g Carbon Fiber Surface Mat is a lightweight non-woven material made from chopped carbon fibers. With an areal weight of 10g/m², it is primarily used as a surface or functional layer in composite laminates rather than as the main structural reinforcement.

The material is formed through a wet forming process, which distributes the chopped fibers across the sheet without the fixed warp and weft structure of woven carbon fiber fabric. After resin impregnation, it can provide a more consistent carbon fiber surface while adding very little material thickness and weight.

This makes the 10g specification suitable for CFRP parts where surface appearance, thin-layer coverage, electrical functionality, or material efficiency needs to be considered together.

Surface Layer in Composite Manufacturing

Unlike woven carbon fiber fabric, which is generally selected for directional reinforcement, this surface mat is designed for the outer or near-surface part of a composite laminate. It can cover the underlying reinforcement and help create a more uniform resin-rich surface after molding.

The 10g/m² weight is particularly suited to thin surface coverage. It adds only a small amount of material while helping to reduce the visual influence of the woven pattern underneath.

Typical functions include:

· Improving surface uniformity
· Reducing visible weave texture
· Providing a consistent carbon fiber surface layer
· Adding limited conductive functionality

The actual surface result depends on resin type, fiber distribution, laminate construction, mold condition, and the finishing process used on the finished part.

Material Structure and Processing

The production sequence is based on chopped fiber dispersion rather than yarn weaving:

Fiber Dispersion and Uniform Distribution

Non-Woven Carbon Fiber Mat Formation

Resin Impregnation During Composite Processing

This structure gives the sheet no fixed fiber direction. During molding, resin can penetrate the dispersed fiber network and bond the mat to the surrounding laminate.

For CFRP production, the mat can be placed over woven fabric, between selected reinforcement layers, or at another defined position in the laminate. The placement should match the intended surface and functional requirements rather than treating the mat as a replacement for the main structural reinforcement.

Surface Finish and Functional Properties

Smoother Composite Surface

The dispersed carbon fibers can help cover the texture of the reinforcement underneath. This is useful when a molded CFRP part needs a more consistent visual surface before painting, coating, or other finishing operations.

Low Material Weight

At 10g/m², the mat is intended for applications where surface coverage is more important than adding a substantial reinforcement layer. It can therefore be incorporated into lightweight composite designs without significantly increasing the material load of the laminate.

Electrical Functionality

Carbon fiber is electrically conductive, so the mat can contribute to conductive composite structures. Depending on the laminate design, potential functions include static dissipation, electrical continuity, and electromagnetic interference control.

For a defined electrical or EMI requirement, the performance should be evaluated on the finished composite. Resin content, fiber contact, laminate thickness, grounding, joints, and component geometry all influence the final result.

Reduced Need for Surface Correction

A more uniform surface layer can reduce the amount of texture correction required after molding. The actual finishing requirement still depends on the mold surface, resin system, curing process, and appearance specification of the final component.

Applications

CFRP Components

The mat can be used as a surface layer in carbon fiber reinforced plastic components where appearance and lightweight construction are important.

Examples include:

· Automotive composite components
· Lightweight vehicle parts
· Sports equipment
· Carbon fiber housings and panels

Electronic and EMI Components

The conductive nature of carbon fiber allows the material to be considered for selected electronic composite structures. It may form part of housings, panels, or enclosures where surface conductivity or EMI control is required.

The shielding performance comes from the complete composite construction, not from the mat in isolation.

Industrial FRP Products

For industrial composite equipment, the mat can serve as a lightweight carbon fiber surface layer. Its suitability for chemical or corrosion-related applications depends on the complete laminate, particularly the resin and any dedicated corrosion barrier.

Potential applications include selected FRP pipes, tanks, containers, filtration equipment, and industrial panels where the composite design calls for a carbon fiber surface layer.

Conductive Composite Structures

The material can also be considered for lightweight conductive composite components used in electrical, energy, and other functional-material applications. Final suitability depends on the required electrical properties and operating environment.

Technical Specifications

Production and Supply

Taizhou Yuruis New Materials Co., Ltd. was founded in 2017 and focuses on fiber composite materials, including carbon fiber products, fiberglass materials, and FRP-related products.

The production process for this mat involves fiber preparation, dispersion, wet forming, sheet formation, cutting, and inspection. Production capacity is listed at 2 million square meters per year, supporting standard orders as well as larger composite material requirements.

For technical inquiries, information about the intended laminate, resin system, processing method, required width, and order quantity helps determine whether the 10g specification matches the application.

Customization

The standard product is supplied at 10g/m² with widths of 1 meter and 1.25 meters. Depending on the production requirement, packaging and other specification details can be discussed before order confirmation.

For a quotation, it is useful to provide the required width, quantity, application, resin system, molding process, and any specific surface or electrical requirements. These details allow the material specification to be reviewed against the actual composite process.

Frequently Asked Questions

Is 10g Carbon Fiber Surface Mat a structural reinforcement?

It is mainly used as a surface or functional layer rather than as the primary structural reinforcement. Woven or unidirectional carbon fiber materials are generally used where defined directional load-bearing properties are required.

What does the 10g/m² specification mean?

It refers to the nominal areal weight of the mat. At 10g/m², the material is intended for lightweight surface coverage where adding a thick reinforcement layer is unnecessary.

Can the mat be used with resin systems?

Yes. The non-woven chopped-fiber structure is designed to be impregnated with resin during composite processing. Wet-out and final surface quality depend on the resin, processing method, pressure, curing conditions, and laminate construction.

Can it improve the surface of woven carbon fiber laminates?

Yes. When placed over woven reinforcement, the mat can help reduce the visibility of the underlying weave pattern and create a more consistent surface. The final appearance also depends on mold and resin conditions.

Does carbon fiber surface mat provide EMI shielding?

It can contribute to conductive and EMI-related composite structures. However, shielding effectiveness must be evaluated on the finished laminate because fiber distribution, resin content, thickness, grounding, joints, and component geometry all influence the result.

Can Yuruis supply different specifications?

The standard specification is 10g/m² with widths of 1 meter and 1.25 meters. Project-specific requirements can be discussed based on the intended application, processing conditions, and order quantity.
