Which of the following is NOT a typical characteristic of composite materials?

Composite materials are known for several key characteristics that make them desirable in various applications. One notable feature is their high strength-to-weight ratio, which allows structures and components made from composites to be both lightweight and strong. This property is particularly advantageous in industries such as aerospace, automotive, and construction, where reducing weight while maintaining structural integrity is crucial.

Corrosion resistance is another significant characteristic of many composite materials. Unlike metals, composites do not rust and can often withstand environmental factors that lead to deterioration, making them suitable for outdoor applications or harsh environments.

Durability is also a hallmark of composite materials. They can withstand various mechanical stresses, impacts, and some environmental conditions over prolonged periods, which contributes to their longevity and reduces maintenance costs.

On the other hand, composite materials may exhibit varying degrees of flexibility depending on the specific types of fibers and resins used. However, they are often designed to be relatively rigid compared to materials that are inherently flexible, such as rubber or certain plastics. Therefore, categorizing composite materials as low in flexibility generally doesn't capture the full range of their potential designs and capabilities. This flexibility varies widely based on the formulation and purpose of the composite, but characterizing them broadly as having low flexibility does not align with the typical properties recognized in
