400g Carbon Fiber Composite Mat

The 400g Carbon Fiber Composite Mat combines 380 g/m² chopped roving with a 20 g/m² carbon fiber mat in a single material structure. The chopped roving forms the main reinforcement layer, while the carbon fiber mat provides the surface layer. Both components are supplied together for composite lay-up.

This construction is intended for composite manufacturers that require a defined reinforcement weight and an integrated carbon fiber surface layer. Compared with handling the two materials separately, the combined format provides a fixed layer arrangement for the corresponding laminate section.

Technical Specifications

The 400 g/m² total basis weight consists of two components. The 380 g/m² chopped roving accounts for the main reinforcement portion, while the 20 g/m² carbon fiber mat forms the surface layer.

Material Structure and Surface Layer

The carbon fiber mat is a nonwoven layer made from chopped carbon fiber. In a composite laminate, it is positioned on the surface side of the reinforcement and becomes integrated with the resin during molding.

The surface layer can cover part of the texture of the reinforcement underneath, which is relevant to CFRP components where surface appearance is part of the material selection. Its nonwoven construction can also conform to curved and irregular molded surfaces.

Lay-Up and Material Handling

The reinforcement and carbon fiber surface layer are supplied as one combined material. This establishes the layer arrangement before lay-up and eliminates the need to separately measure and position the two corresponding materials for each laminate section.

For repeated production, a fixed material configuration can make cutting and layer preparation more consistent. Actual processing requirements depend on the resin system, mold design, curing conditions and production equipment used for the finished component.

Applications

Width and Custom Supply

The listed width range for EMKC400 is 150–3200 mm. Width selection can be based on mold dimensions, cutting requirements, material utilization and the customer's lay-up process.

For a project quotation, customers can provide the required width, estimated quantity, roll requirements and application. Yuruis can then confirm the available production specification and packaging arrangement.

FAQ

What is the total weight of the 400g Carbon Fiber Composite Mat?

The total basis weight is 400 g/m², consisting of 380 g/m² chopped roving and 20 g/m² carbon fiber mat.

Can EMKC400 replace separate chopped roving and carbon fiber mat?

EMKC400 is supplied as a combined structure of chopped roving and carbon fiber mat. Whether it can replace separately applied materials depends on the laminate design, resin system and molding process.

Is the 20 g/m² carbon fiber layer the main structural reinforcement?

The 20 g/m² carbon fiber mat primarily functions as the surface layer. The main reinforcement portion is the 380 g/m² chopped roving. The structural properties of the finished laminate depend on the complete material system and laminate design.

What widths are available for EMKC400?

The listed width range is 150–3200 mm. The final width and roll requirements should be confirmed according to the mold, cutting method and production process.

Can the material be used for curved composite parts?

The nonwoven carbon fiber surface layer can conform to curved and irregular surfaces. Final suitability depends on the resin, mold geometry and processing conditions.

What information is needed for a quotation?

Customers can provide the required width, estimated quantity, application, roll requirements and delivery destination. Details of the molding process can also be provided when a specific production application is involved.

Can Yuruis supply EMKC400 for regular production?

Yes. Supply for regular production can be discussed based on the required specification, quantity and production schedule.
