| Question | Answer |
| What is Composites -Two or more materials mixed together by some kind of bonding. -The composite has improved mechanical, functional & aesthetically. | -Excellent strength-to-weight ratio -Useful for many products |
| Glass reinforced plastic (GRP) Made from thermosetting plastic resin that has been rein forced using very fine glass |

|
| Carbon Fibre The carbon fibres are able to take tensile loads, are set onto a polymer matrix that is able to take big loads. much stronger than GRP. |

| Medium Density Fibreboard (MDF) Most common and widespread composite material. It is mainly made from waste wood. It can be laminated to improve its strength/aesthetics. |

|
| Chipboard Like MDF, waste wood is glues together under heat and pressure leaving a smooth surface. It comes in normal and high density | Normal:-most common -fairly soft High:-hard -solid Uses- table tops & internal fire doors |
| Laminates produced by bonding two or more layers of material. It is a very stable material. They do not warp or misshape and they are easy worked. |

| Plywood Made from layers of veneers that are bonded together using glue (veneers are thin layers of wood). Plywood is strong as the grain goes different directions. |

| Blockboard Made up of strips of softwood; they are positioned edge-to-edge. The side of the sheet that is produced is covered with veneer then glued together | For table of Composites go to book pages 31-32 |
