1. Know these functional groups:
acid, alcohol, amine, amide, epoxide, carbonate, ester

2. Be able to recognize and differentiate between these polymer structures:
polyethylene, polypropylene, polyester, nylon, Kevlar, PVC, silicone, polycarbonate

4. Oils, elastomers, molding compds - depending on MW
Low Tg
Stinks when it crosslinks

6. Rigid
Formed by adding plasticizer
"vinyl"

8. Non-crystalline
Strong & tough
Stiff chains, H bonding betwn chains
High TM

10. Strong, tough
Fibers

12. Nylon cousin
Very strong
Very stiff chains
Fibers

14. Spaghetti
LDPE - low MW, short branches
HDPE - higher MW, crystalline (no branches)
UHMWPE - very high MW, crystalline

15. Like an organic salt

18. Composites
Matrix - metallic, ceramic, polymeric
Reinforcement - particulates, fibers

19. Composites
Matrix - metallic, ceramic, polymeric
Reinforcement - particulates, fibers
Fibers - conts, disconts
glass, carbon

20. Composites
Role of matrix in FR composites - transfer stress to fibers & protect fibers
