Thickness specifications, main applications, and processing precautions for carbon fiber sheets
To meet the needs of different applications, carbon fiber sheets are often available in various thicknesses. The thinner the carbon fiber sheet, the easier it is to bend without fatigue; conversely, thicker carbon fiber sheets are practically impossible to bend, which is very useful if a strong, high-rigidity material is needed to meet design requirements.
Carbon fiber sheets come in various thicknesses, and these thicknesses can vary slightly depending on the manufacturer. While manufacturers sometimes offer customized products, in most cases, carbon fiber sheets are available in the following thicknesses and sizes:
1. 0.013 inches (0.33 mm) — This is an extremely thin carbon fiber sheet, roughly the thickness of two sheets of computer paper. It can be easily cut with a pair of household scissors and is also easily bent around a one-inch cylinder. This thickness of carbon fiber sheet is typically used for decorative purposes.

It can be easily cut with a pair of household scissors and is also easily bent around a one-inch cylinder. This thickness of carbon fiber sheet is typically used for decorative purposes.
2. 0.020 inches (0.50 millimeters)—about the thickness of five sheets of paper—can be cut with a heavy-duty pair of scissors. They can still be bent, but not as easily as 0.013-inch carbon fiber sheets. Sheets of this thickness can be bent around a cylinder of about four inches. When used to cover substrates with minor imperfections, the added thickness and stiffness also provide some camouflage.
3. 0.032 inches (0.80 mm) — This is a fairly rigid carbon fiber sheet, but it still retains some flexibility. It's almost as thick as an audio CD. Carbon fiber sheets of this thickness are typically flat, but they can be bent around cylinders with a diameter of 10-12 inches. It is primarily used as a semi-rigid veneer or lightweight structural material. It can be cut with tin snips, a saw, a razor, or a grinding wheel (such as a Dremel tool). If a smooth edge is required, the cut edges will need to be sanded with 220-grit sandpaper.
4. 0.125 inches (3.175 mm) — This ⅛-inch thick carbon fiber sheet is extremely durable and strong. It is also a perfect material for structural applications. When cutting, a saw, carbide, bimetallic, or diamond-coated tools must be used, and the edges must be sanded smooth.
5. 0.25 inches (6.35 mm) – At a thickness of 1/4 inch, these carbon fiber sheets are redundant for most applications. However, by cutting these sheets, they can be used to machine small carbon fiber parts. When cutting carbon fiber sheets this thick, specialized

As mentioned above, different cutting tools are used when cutting carbon fiber sheets of each thickness, but the use of jigsaws or circular saws for rapid cutting is not recommended as this generates a large amount of carbon fiber dust, which can irritate the eyes and lungs.

Even rapid cuts often leave very rough edges when cutting carbon fiber sheets. It's best to protect the surface from scratches with tape or similar material when cutting carbon fiber sheets. Wearing appropriate personal protective equipment is always a good idea for operators cutting carbon fiber sheets; key protective gear includes goggles, long sleeves, a face mask, and gloves.
