Which material class has the lowest specific stiffness?Answer 1 Question 10Which material class has the highest specific stiffness?

The material class with the lowest specific stiffness is typically polymers. They have a lower specific stiffness compared to metals and ceramics.

On the other hand, the material class with the highest specific stiffness is typically composites, especially those reinforced with carbon fibers. They have a higher specific stiffness compared to metals, ceramics, and polymers.

The material class with the lowest specific stiffness is typically polymers. They have low stiffness and strength but they are very light.

On the other hand, the material class with the highest specific stiffness is often ceramics or composite materials. These materials are very stiff and strong, but they are also quite heavy.

However, it's important to note that specific stiffness can vary widely within each material class depending on the specific material and its processing.
