Xinbo Composites is a professional manufacturer of premium carbon fiber sheets. Our carbon fiber sheets and plates in top-quality gloss and matte are available in various sizes and thicknesses.
Our carbon fiber sheets are 100% carbon fiber using top-quality 3k Toray prepreg. Our mold pressing technology ensures stiffness is improved by approximately 30% compared to manually produced carbon fiber sheets, we produce carbon fiber sheets manufactured with perfect surfaces. We also custom carbon fiber panels fit your specs, including custom dimensions, custom thickness (+/- 0.05 mm tolerances), and CNC carbon fiber sheets machining.
We customize carbon fiber sheets with mold press technology, improve the strength and also offer a perfect surface.
Xinbo Composites customizes carbon fiber sheets to fit customers’ projects. We manufacture and supply carbon fiber sheets including cutting of carbon fiber sheets. All required operations are delivered with a high-precision 4-axis CNC milling machine. We also provide milling services at your desired thickness (e.g. drilling holes, slots for counter-sunk screws) and threading of finished details. In addition, we also supply coating services.

Carbon Fiber Sheets FAQ
- What is the maximum size of carbon fiber sheets? Do you supply big size carbon fiber sheets? Is export delivery of big size carbon possible?
We supply big size / large carbon fiber sheets sized 100×200 cm, and upon request, we also supply big size carbon fiber sheets that are shipped by freight forwarding, which in practice is economical for large quantities only – contact us
- What kind of finish is available for carbon fiber sheets? Are carbon fiber sheets with a matt finish available?
We supply carbon fiber sheets with gloss and matte finishes.
- Do you provide services related to carbon fiber sheet cutting with a CNC milling machine?
Yes we do. We offer carbon fiber sheet cutting with a 4-axis CNC milling machine. For a quotation please send the drawing in .dxf or step format, along with information regarding sheet thickness and quantity required.
- Do you supply carbon fiber sheets of various thicknesses customized to individual needs? What accuracy can your company guarantee?
Our standard carbon fiber sheets are manufactured with accuracy up to ~ + 0.1mm. Upon request, we will cut carbon fiber sheets to the required thickness with an accuracy of +/- 0.05mm.
- Do you supply unidirectional carbon fiber sheets or biaxial and triaxial carbon fiber sheets?
We supply carbon fiber sheets with 2/2 (twill) or 1/1 (plain) weave but we also supply unidirectional carbon fiber (UD) or biaxial and triaxial carbon fiber sheets.
- Are carbon fiber sheets of quasi-isotropic type available?
We supply carbon fiber sheets with layers oriented at 0/90 degrees, but upon request, we also supply carbon fiber sheets with layers oriented at 0/90/-45/+45 degrees namely quasi-isotropic carbon fiber sheets.
- What is the thermal resistance of carbon fiber sheets?
Carbon fiber sheets offer thermal resistance up to 140~150oC.
- How can I cut carbon fiber sheets in my workshop?
The carbon fiber plates we make are easy to process. They do not flatten when milling on a CNC machine, and the edges are sharp and nice. The carbon plates we make can also be easily machined with household tools such as an angle grinder, drill, file, sandpaper, etc.
- Can carbon fiber sheets be painted?
Actually, any further treatment depends on the intended use. All supplied carbon fiber sheets (and ones made from epoxy resin) offer resistance to UV. However in the case of long duration or repeated exposure to sunshine (UV radiation) it is recommended to apply a layer of clear top coat (e.g. Polyurethane and Acrylic based) on the outer side of the carbon fiber sheet to ensure total protection against UV radiation.
