→ The skin of aircraft wings were originally made from fabric.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.
