1a. Name a re-inforced composite material. |
| Carbon Fibre Re-inforced Plastic (CFRP) |
| 1b. For the re-inforced composite material you named in 1a, name / describe a product in which it is used. |
| Modern Fighter Aircraft |
| 1c. List three reasons for using the re-inforced composite material you have named, in the product you have described. |
| (i) CFRP is lightweight, which helps
improve the performance of the fighter plane. The reduction in weight
means that fuel consumption is cut considerably. Planes composed of a high
percentage of CFRP require less fuel, going further / travelling faster,
than comparable planes made of traditional materials (specialist alloys). (ii) CFRP can be finished in a number of ways, including spray painted. This allows for camouflage to be added, including any insignia. Anti-radar paint can also be applied to it. (iii) CFRP can be moulded into a variety of complex shapes, allowing fighter planes to be designed that are much more manoeuvrable, than planes manufactured from metal alloys. |
