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 material classification?Fiber-reinforced polymer (FRP) composite
2. What is the common polymer matrices?Unsaturated polyester, vinyl ester, and epoxy resins
3. Why is fiberglass lighter than metal?The glass fibers are very light, and the plastic that holds them together is also light, so the whole material is lighter but still strong.
4. How is fiberglass made?Glass fibers are spun into thin threads, then mixed with a plastic resin. The mixture is poured into a mold and hardened, creating a solid shape.

Composite Material: A material engineered from two or more constituent materials with significantly different physical or chemical properties.
Polymer Matrix: The continuous phase in a composite material that surrounds and binds the reinforcing fibers.
Thermoset Resin: A polymer that irreversibly cures from a liquid or malleable state into a rigid solid through heat or chemical reaction.
Strength-to-Weight Ratio: A measure of a material's strength relative to its density, crucial for lightweight structural applications.
