Polymers are made up of many tiny molecules strung together to form long chains (and sometimes more complicated structures). Natural polymers are found in many forms such as horns of animals, tortoise shell, shellac (from the lac beetle), rosin (from pine trees), rubber (obtained from several types of trees), asphalt, and tar from distillation of organic materials. Synthetic polymers …

Ionic Crystals

The atoms of ionic crystals are held together by electrostatic forces (ionic bonds). Ionic crystals are hard and have relatively high melting points. Table salt (NaCl) is an example of this type of crystal.

Composite Material

A composite material is any material in which two or more separate materials have been combined to make a single construct having more desirable properties. Composites are probably the most common structural materials in the world, and have always been an essential part of our lives. Concrete, paper, corrugated cardboard, plywood, fiberglass, bamboo, cornstalks, trees, …
