Kevlar is most notable for providing high tensile strength and is used in which protective area?

• A. Body armour and PPE garments.
• B. Water filtration membranes.
• C. Electrical cables insulation.
• D. Concrete reinforcement.

Answer: (A)

Kevlar’s standout feature is its very high tensile strength and its ability to absorb a lot of energy without breaking, while still being lightweight. That combination is perfect for protective gear that must resist impacts and cuts without weighing people down. In body armour and PPE garments, Kevlar fibers are used to make fabric laminates or composites that stop bullets or protect against cuts and abrasions, giving reliable protection while allowing mobility. This is why you see Kevlar in bulletproof vests, helmets, and cut-resistant gloves, among other protective items.

Other areas don’t rely on those same protective properties in the same way. Filtration membranes need precise pore structures to separate substances, which isn’t what Kevlar is optimized for. Electrical cable insulation requires dielectric, electrical-insulation materials; Kevlar is strong but not an insulator in the way those polymers are. Concrete reinforcement typically uses steel or other fiber-reinforced polymers chosen for compatibility with cement and long-term durability in a harsh alkaline environment, where Kevlar isn’t the standard choice.
