Aircraft construction has seen a fundamental shift in the materials used in that industry. In the past, aluminum alloys were used almost exclusively for aircraft outer skin and stringers. Today, these components are manufactured primarily from carbon-fiber reinforced plastic (CFRP).
The first industrial application of these materials goes back to 2007, when Boeing used them in its B787 and Dreamliner aircraft. CFRP has been further enhanced since then and today the Airbus A350WXB consists of more than 40% CFRP materials, to cite one example.
