DuPont's Aramid Kevlar is described as which of the following?

• A. A synthetic polymer, has poor compression properties
• B. A natural fiber with strong compression
• C. A ceramic fiber for high temperatures
• D. A metal fiber with high density

Answer: (A)

Kevlar is a synthetic polymer fiber known as an aramid, made from aromatic polyamide chemistry. Its standout feature is very high tensile strength and toughness, which is why it’s used in protective gear and in reinforced composites. However, its compressive properties are relatively poor—the fiber tends to buckle and doesn’t resist compression as well as it does tension. That combination—synthetic polymer origin with excellent tension/toughness but weaker compression performance—fits Kevlar's profile best, unlike natural fibers, ceramic fibers, or metal fibers.
