Many FGCI customers and subscribers have asked questions that were related to a better understanding of Carbon Fiber. So, we sat down with our technician, Pat Hery, and informed him of the common questions, and we must say, the responses were quite interesting!
Interview:
What are the common uses for carbon fiber?
There are many common uses for carbon fiber such as golf clubs, bicycles, aircrafts, automotive, iPhone cases. But, we usually see carbon fiber used as aesthetics, like car parts, hoods and speaker boxes. Unless used for race car or boats were speed is the demand.
What are the advantages of using carbon fiber?
The advantage is, it has the same thickness compared to steel. And as far as stiffness and strength the comparison will require more fiberglass to get the same yield.
What is the prep method before the application process?
The method depends solely on the mold or if they are overlaying a part. Using epoxy or Vinylester can also be a determining factor. Now let’s say they decide to use epoxy, then, they need to determine if the epoxy is high temp due to the fact that most epoxies will soften up in Florida or in an area that is hot. If they are overlaying a part or making a one-off, they will laminate the carbon, put an extra coat of resin, sand with a 320 and apply an automotive clear.
What are the different ways to apply?
The different methods to apply carbon fiber depend on the surface area one is trying to go over. Carbon Fiber doesn’t like anything but a general curve. When it comes to the application, most will spray super 3M 77 so once the carbon is put in place, it won’t move when doing a thorough wet out of the carbon.
Does the thickness of the carbon matter?
When it comes to thickness of the carbon, this will be important as it can dictate the maximum strength you are looking for. Lastly, the thickness of the layup will depend on what you are trying to achieve.
