What is Dry Carbon?
Dry carbon, also known as pre-preg carbon, is a high-performance carbon fiber material used extensively in aerospace and automotive industries for its lightweight and strength properties. The production process involves pre-impregnating the carbon fiber with resin, followed by baking it in an autoclave to remove any trapped air and excess resin.
