Which material is given as an example of a new material with innovative properties?

• A. Steel
• B. Kevlar
• C. Glass
• D. Copper

Answer: (B)

New materials with innovative properties are designed to deliver performance beyond what traditional materials offer. Kevlar fits this idea because it is a high-performance aramid fiber with an exceptional strength-to-weight ratio and outstanding resistance to impact and abrasion. This combination is hard to achieve with common materials, making Kevlar particularly valuable for protective gear like body armor and helmets, as well as advanced composites. In contrast, metals like steel and copper, or glass, are well-established and known for more conventional properties such as heaviness, brittleness, or conductivity, without the same standout lightweight toughness. That distinctive performance is why Kevlar is highlighted as an example of a new material with innovative properties.
