Materials

• Ceramics are non metallic solids with high melting points they aren't made from carbon based compounds
• Ceramics are excellent insulators of heat and electricity

  They tend to be very brittle and stiff
• Composites are made of one material embedded in another material.
• Thermosoftening polymers are made of individual tangled chains of polymers

  Weak forces between cahins

  Flexible, can be melted and then remoulded
• Thermosetting polymers have cross-links between polymer chains

  Strong ,hard and rigid

  Doesn’t melt when it’s heated
