Which of the following characteristics does carbon fiber exhibit?

The characteristic that carbon fiber exhibits is UV-resistance. Carbon fiber is known for its exceptional strength-to-weight ratio and durability, which includes resistance to ultraviolet light. This attribute is essential for materials exposed to sunlight, as UV exposure can degrade many polymers and composites over time. Carbon fiber maintains its structural integrity and performance even when subjected to prolonged sunlight exposure.

The high strength and lightweight nature of carbon fiber make it a preferred material in various industries, particularly in aerospace, automotive, and sporting goods. Its design allows it to perform well in applications where both strength and resistance to environmental factors are critical.

Considering the other options, carbon fiber does not exhibit high density; rather, it is lightweight. It typically has low brittleness compared to other materials because of its unique composition, which allows for flexibility in design. Additionally, carbon fiber is characterized by its flexibility rather than low flexibility, as it can often be engineered to meet specific tensile and compression requirements, allowing for some degree of adaptability while still maintaining high strength.
