Polymer a solid form resulting from the arrangement of atoms, ions, or molecules in definite geometric patterns 2. ceramic a plastic with high elongations that can be recycled 3. thermoset a carbon fiber embedded in a polymer resin matrix 4. thermoplastic a long, chain-like set of molecules made up of repeating units joined end to end 5. crystal a hard, brittle, heat- and corrosion-resistant material made by subjecting a nonmetallic mineral mixture to intense heat 6. composite a plastic with low elongations that cannot be recycled asap

1. Polymer refers to a lengthened, chain-like molecule comprising repeated units associated end to end.  

2. Ceramic refers to a hard, brittle, corrosion and heat tolerant substance formed by administering a non-metallic mixture of minerals to intense heat.  

3. Thermoset refers to the plastics, which exhibit low elongations and cannot get recycled again.  

4. Thermoplastic refers to the plastics, which exhibit high elongations and can be recycled.  

5. Crystal refers to the solid form originating from the organization of ions, atoms, or molecules in precise patterns of geometry.  

6. Composite refers to a carbon fiber entrenched in a polymer resin matrix.
