SHORT: 1) _____ A dielectric material in which polarization is induced by the application of external forces. Piezoelectric. 2) ____ A dielectric material that may exhibit polarization in the absence of an electric field. Ferroelectric. 3) _______ is a low molecular weight polymer additive that enhances flexibility and workability and reduces stiffness and brittleness resulting in a decrease in the galss transition temperature Tg. Plasticizer. 4) Why does precipitation hardening strengthen a metal alloy ( stressy and T.S? They hinder dislocation movement. LONG: 1) What are three ways to fabricate fiber-reinforced plastics? Pultruision, filament winding, and prepreg production) 2) Draw the specific volume vs. temperature for totally amorphous, semicrystalline, and crystalline polymers? Pg 546 3) What are the five different regions of viscoelastic behavior? Glassy, Leathery, Rubbery, Rubbery flow, viscous flo pg. 530 4) Name the five polymer additives? Fillers, plasticizers, stabilizers, colorants, flame retardants. 5) If I was given a list of of materials: Si doped with 10 22 m -3 of Al Si doped with 10 22 m -3 of P Ge doped with 10 22 m -3 of Al Ge doped with 10 22 m -3 of P What should I take into consideration for the highest conductivity? Choose highest mobility. 6)
