Dry carbon is the highest-quality version of carbon fiber products that are produced. Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed vacuum (autoclave) to properly cure. This method creates the least amount of waste and forms a lighter version of carbon than the "wet" method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. Satisfy your carbon urge with this dry carbon trunk spoiler!
