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 chemical classification?Synthetic aromatic polyamide fibers
2. What is the structural basis?Linear alignment of polymer chains with strong intermolecular forces (hydrogen bonding)
3. What are aramid fibers and why are they so strong?Aramid fibers are special threads made from synthetic aromatic polyamides. Their molecules line up straight and stick together with strong bonds, giving them a strength that can be stronger than steel.
4. How do aramid fibers stay strong even when they get very hot?They have a high melting point above 500°C because their molecules have rigid rings that don’t move easily. This lets them keep their shape and strength even in extreme heat.

Aromatic Polyamide: A synthetic polymer containing benzene rings and amide linkages in its molecular structure.
Polymerization: The chemical process of linking small monomer molecules into long polymer chains.
Tensile Strength: The maximum stress a material can withstand while being stretched or pulled before breaking.
Modulus: A measure of a material's stiffness or resistance to elastic deformation under stress.
