Q & A

What is carbon fiber?

Carbon fiber is a material made from pure carbon filaments that are incredibly strong when pulled under tension, yet flexible. It is known for being extremely strong and lightweight.

How does carbon fiber compare to steel in terms of strength?

Carbon fiber is five times stronger than steel and two times stiffer, but it is much lighter than steel, making it ideal for applications where strength and lightness are important.

What are the main components of carbon fiber?

Carbon fiber is made from a mixture of materials such as polyacrylonitrile, rayon, and pitch, which form the carbon fiber after undergoing certain processes.

Why is epoxy resin used in carbon fiber production?

Epoxy resin is used in carbon fiber production because it has a very high hardness level, which helps the carbon fiber sheets become strong and rigid after curing.
