About Dry Carbon Fiber

Dry Carbon Fiber vs Wet Carbon Fiber — What’s the Difference?

Not all carbon fiber parts are made the same. The biggest distinction comes down to how the carbon is processed — commonly known as dry carbon and wet carbon. Both use genuine carbon fiber weave, but the production method, finish, and performance are completely different.

Manufacturing Process

Dry carbon fiber parts are produced using a pre-preg (pre-impregnated) carbon cloth, where the exact amount of resin is pre-applied by the manufacturer. These sheets are then vacuum-sealed and cured under high pressure and temperature in an autoclave, removing excess air and resin.
The result is a light, extremely strong, and precisely formed component — the same process used in motorsport and aerospace applications.

Wet carbon fiber, on the other hand, uses a hand-lay or wet-lay method. The carbon cloth is laid into a mold and liquid resin is manually brushed or poured over it before curing. Because it’s not vacuum-bagged or autoclave-cured, there’s usually more trapped resin and air pockets, leading to a heavier part and a less uniform finish.

Weight & Strength

Dry carbon fiber is roughly 30–50% lighter than wet carbon. This is due to the controlled resin ratio — just enough to bind the fibers without unnecessary weight.
By comparison, wet carbon or carbon-over-fiberglass parts can be up to 70% heavier, since excess resin and fiberglass layers add mass without increasing stiffness.
For reference:

• Carbon Fiber Density: ~1.55 g/cm³
• Fiberglass Density: ~2.6 g/cm³

Dry carbon also offers a much higher modulus of elasticity (~125 GPa), giving it outstanding rigidity under stress — ideal for aerodynamic and high-load components.

Visual & Structural Differences

• Backside: A true dry carbon piece will look identical front and back — you can see the same woven pattern throughout.
  Wet carbon or fiberglass-backed parts often have a dull, uneven underside with visible fiberglass texture or color variation.
• Edges: Solid dry carbon has clean, uniform black edges.
  Wet carbon or overlay parts may show a white or grey line along the edge, revealing the fiberglass underneath — sometimes hidden with black paint trim.
• Finish: Dry carbon typically has a consistent matte or satin finish, while wet carbon can appear glossy but uneven due to hand-applied resin.
