Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary engineering advantage?Exceptional strength-to-weight ratio, enabling lightweight yet strong structures
2. What is the key failure mechanisms?Fiber fracture, matrix cracking, fiber-matrix debonding, and delamination
3. How do composites get their strength?The fibers give the material stiffness and strength, while the matrix holds the fibers together and protects them.
4. Why do engineers use composites instead of just one material?Composites can be designed to have special properties, like being very strong but light, which helps make cars, planes, and wind turbines work better.

Monolithic Material: A material made from a single constituent material, not a combination.
Fiber-Reinforced Polymer (FRP): A composite material where strong fibers are embedded in a polymer matrix.
Delamination: The separation of layers within a layered composite material under stress.
