Question

Carbon fiber is made up of extraordinarily thin filaments - about one hundredth the

thickness of a human hair.
1) True
2) False

Answer 1

The correct option is;

2) False

Step-by-step explanation:

Carbon fiber are also known as graphite fiber is a very thin stiff and light fiber with diameter of about 5 - 10 micrometres. Carbon fibers have high tensile strength, high chemical resistance, and high temperature tolerance with a low thermal resistance

The diameter of the human hair is 17 to 181 μm

Dividing the minimum diameter of carbon fiber by the maximum diameter of the human hair, we have;

5/181 = 0.0276 ≈ 0.03 which is more than a one hundredth or 0.01 hence the correct option is False.
