What is dry carbon fiber

Carbon fibers are thin strands of fiber made up of carbon atoms, these fibers are then combined with other materials to form a composite. Most carbon fiber products are made by combining carbon fibers with epoxy resin to form a carbon fiber reinforced polymer (often referred to as carbon fiber).

There are two categories of carbon fiber reinforced polymers which differ on the ratio of carbon to epoxy resin: wet and dry carbon fiber. More than 90% of all carbon fiber products are made with wet carbon fiber which contains more epoxy than carbon in the polymer. This type of carbon fiber is cheap and easy to produce however it is heavier and weaker than dry carbon fiber.

Dry carbon fibers contain more carbon than epoxy but is significantly more difficult to produce than wet carbon fiber as the fibers need to be specially treated into “pre-preg” fibers and undergo an autoclave (heat and vacuum treatment) in order to make a finished product. The resulting product is much stronger and lighter compared to wet carbon fiber. All aerospace grade carbon fiber components are made with dry carbon fibers.
