- The skin of aircraft wings were originally made from fabric.
- Sheet metal alloys were then used to replace the fabric as they provided strength to the skins’ structure that the fabric did not.
- These sheet metals primarily included aluminium, titanium and steel alloys.
- More recently composite materials have been used for their high strength to weight ratios.
- These include carbon fibre epoxy resin, GLARE and other fibre reinforced metal laminates.
Other answers could include:
- Material developments regarding the frame of the wing where timber was originally used, followed by steel, aluminium/titanium alloys and modern day composite materials.
