- Toughness: This is the resistance of a material to being broken when we striked it. The tools we use to strike objects and the  sports are made of tough materials the opposite of though is brittle. They are easily to broke.

-  Deformability: This is the ability of a material to be deformed. THe opposite of demormability is rigidity. If a material is deformable it can be elastic or plastic (if it stays deformed when the force that demormed it it has disappear, like clay or plastiline).

- Ductility: This is the ability of a material to be stretched into a wire. Nylon and cooper are ductile materials.

- Malleability: This is the ability of a material to be pressed or rolled into a sheet. ]]> 2018-11-23 13:02:29 UTC https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/307260208 TYPES OF MATERIALS ClaraandElvira https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/307263124 Woods]]> 2018-11-23 13:18:55 UTC https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/307263124 TYPES OF MATERIALS ClaraandElvira https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/307263964 Textiles]]> 2018-11-23 13:23:44 UTC https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/307263964 TYPES OF MATERIALS ClaraandElvira https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/308733276 Metals]]> 2018-11-28 12:41:50 UTC https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/308733276 TYPES OF MATERIALS ClaraandElvira https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/308734338 Plastics]]> 2018-11-28 12:45:08 UTC https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/308734338 TYPES OF MATERIALS ClaraandElvira https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/308735531 Construction materials]]> 2018-11-28 12:48:24 UTC https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/308735531 WOOD ClaraandElvira https://padlet.com/ClaraandElvira/1AClaraRodriguezandElviraRusillo/wish/308736191 PROPERTIES OF WOOD:
  • Tensile strength (resistance to stretching)
  • Compressive strength (resistance to being crushed)
  • Flexural stregth (resistance to bending)
  • Hardness 
  • Toughness
  • Thermal and electrical conductivy
  • Sound conductivy
  • Colour
  • Density

Underisable properties in techical applications:

  • Combustion (wood burns easily)
  • Moisture (in humid enviroments wood absorves moisture and this causes it to dilate and bend)
  • Rotting and insect attack (outdoor wood is easily attacked by mould fungi that make it rot)

Wood derivatives ar usually obtained from leftover wood (chips, sawdust, etc).
