A: What are DRY and WET Carbon Fiber?
Q: Of the many different terms associated with carbon fiber, the terms "dry" and "wet" carbon fiber may cause the most confusion. Each type has its own set of advantages and disadvantages, but understanding the differences will help lead you toward making a better-informed decision about which to choose for your needs.
The terms “dry” and “wet” in carbon fiber refer to how the product is produced or manufactured. Each has its own unique approach, but the result is actually quite different in terms of weight, strength, and other factors.
A:What is Dry Carbon Fiber?
Q:Dry carbon fiber is formed by 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 to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The vacuuming process of making dry carbon means that there are fewer pinholes and almost no air pockets that form in the carbon. Dry carbon is the highest quality version of carbon fiber products that are produced.
However, it is 3 to 4 times more expensive to produce than its counterpart.
Advantages of Dry Carbon Fiber
40% of steel weight
2 times harder than steel
Superior manufacturing process
Uses a dry finish for enhancing its cosmetic appearance
Disadvantages of Dry Carbon Fiber
.Almost four times as expensive to produce
.Will fade if not adequately maintained
Q:What is Wet Carbon Fiber?
A:Wet carbon fiber uses a different method of manufacturing. In this process, the carbon fiber is laid out by hand into a mold using a dry cloth. Then, a mixture of two parts resin, and one part carbon is put together and applied to the cloth before being placed inside a bag and heated in a vacuum. Due to this method, carbon fiber weaves are far more affordable.
However, wet carbon fiber is subject to having more air bubbles which can create weaknesses, and wavy fiber weaves which are less consistent that the dry counterpart. Because it is far less expensive to create carbon fiber using the wet method, most carbon fiber parts are created “wet”.
Advantages of Wet Carbon Fiber
.Far cheaper to produce, meaning a less expensive product
.Has a very shiny, wet appearance which can be attractive
Disadvantages of Wet Carbon Fiber
.Weaker and heavier than its dry counterpart
.Will fade unless properly maintained
