Which of the following is NOT an advantage of composites?

The assertion that lower environmental impact is not an advantage of composites focuses on the current challenges associated with the lifecycle of composite materials. While composites do offer many benefits, such as durability, the ability to form complex shapes, and higher specific strength, their environmental impact often raises concerns, particularly during the production process and at the end of their lifecycle.

Composites can be made from materials that require significant energy to produce and may involve toxic substances that can contribute to pollution. Moreover, they often do not decompose easily, leading to disposal issues that can further harm the environment. In contrast, the other advantages highlight key characteristics of composites that make them favorable for a variety of applications, such as their resistance to wear and corrosion, lightweight nature, and versatility in design. These attributes contribute positively to performance but do not inherently address environmental considerations.
