2. What are Materials?
 That’s easy! Look around.
 Our clothes are made of materials, our
homes are made of materials - mostly
manufactured. Glass windows, vinyl siding,
metal silverware, ceramic dishes…
 Most things are made from many different
kinds of materials.

3. Kinds of Materials
 Metals: are materials that are normally
combinations of "metallic elements". Metals are
quite strong but malleable and tend to have a
lustrous look when polished.
 Ceramics: are generally compounds between
metallic and nonmetallic elements.They are
insulating and resistant to high temperatures
and harsh environments.

4. Kinds of Materials
 Plastics: (or polymers) are generally organic
compounds based upon carbon and hydrogen.
They are very large molecular structures.
 Semiconductors: have electrical properties
intermediate between metallic conductors and
ceramic insulators.

5. INTERESTING DEVELOPMENTS
 MICRO BATTERIES:
with size of few microns!
layers made with self assembling viruses!!

6. INTERESTING DEVELOPMENTS
 Nano coated textiles:
Durable
Breathable
Wrinkle resistant
Stain resistant

7. INTERESTING DEVELOPMENTS
 Radomes:
Special enclosures
for antennae;
Protect from atmosphere!
without attenuating signals!!
@ Many space / related research centres
