The atomic structure of Carbon fiber (CF) is :
similar to that of graphite, consisting of sheets of Carbon atoms arranged in a regular hexagonal pattern
different from that of graphite, consisting of sheets of Carbon atoms arranged in a regular hexagonal pattern
similar to that of graphite, consisting of sheets of Carbon atoms arranged in a regular circle pattern
True or false: Steel is Strongger than Carbon Fiber.
True
False
Which one is false about the properties of carbon?
High stiffness
Low tensile strength
Fire resistance
Nonpoisonous, Biologically inert
Fill in the blank: (Benefits of CF)
Due to the way carbon fiber absorbs sound waves, it can be an excellent material for (a) reduction
True or False: Stabilizing process is performed by heating the fibers in air for 30-120 minutes at 200-300° C
True
False
The fibers are coated after the surface treatment to prevent them from (a) during winding or weaving.
In the spining process, the polyacrylonitrile plastic is turned into fiber, the plastic is mixed with certain chemicals and pumped through tiny jets into a chemical baths or (a) where the plastic coagulates and solidifies into fibers. The fiber then washed and stretched into desired fibers diameter.

What messages about the future of CFs could you infer from Volume 01?
People will no longer use carbon fibers in large scale industries due to its high cost and environmental issues
People think that using carbon fibers should be banned all over the world
People hope that carbon fibers could help them live on other planet
People could use carbon fibers as alternative materials in many industries
