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?Composite material composed of ligno-cellulosic fibers and thermoplastic polymers
2. What is the key additives?Coupling agents, lubricants, UV stabilizers, colorants, biocides
3. What is a wood-plastic composite?Wood–plastic composites are materials made by mixing wood fibers or flour with plastic. The mix becomes strong and can be shaped into many useful products.
4. Why are wood-plastic composites good for the environment?They use recycled wood and plastic, keeping waste out of landfills. They also last longer than untreated wood, so we need fewer replacements.

Ligno-cellulosic Material: Plant-based fibers, such as wood, straw, or bamboo, rich in lignin and cellulose.
Thermoplastic Polymer: A plastic that can be repeatedly softened by heating and hardened by cooling, enabling reshaping.
Interfacial Adhesion: The strength of the bond between the wood fibers and the plastic matrix in a composite.
