The History of Aircraft Materials 1 The History of Aircraft Materials Questions to answer in this module… – – – – 2 What is the brief history of the materials used to construct aircraft? Why were these materials adopted? Why did some materials replace others? What is the future for materials in aircraft? 1843 - Rubber Charles Goodyear – Vulcanization – – 3 Tires Seals and gaskets 1903 - First flight - Wright Brothers Aluminum engine block Spruce & steel wire structure Fabric skin 4 1903 - Wright Brothers 5 Why wood and wire structure? Why fabric skin? 1903 – Aluminum Engine Block Most internal combustion engines of the time were of cast iron construction 6 1907 – Plastic Leo Hendrik Baekeland – refines plastic production to create bakelite 7 1915 – All Metal Airplane Hugo Junkers Steel tubing Sheet iron skin 8 1916 - Stressed Skin Construction LFG Roland C.II 9 Stressed-Skin Construction Why stressed-skin? Skeleton-like space frame construction used for non-stressed skin aircraft. 10 1926 - Semi-Monocoque Construction Ford Tri-motor 11 Semi-Monocoque Construction Cutaway view semi-monocoque construction 12 1930’s – Increased Aluminum Use Duralumin and Alclad 13 1931 - Stainless Steel Construction Budd BB-1 Pioneer 14 Steel/ Stainless Steel vs. Aluminum So why not build all aircraft out of stainless steel? Corrosion resistance Weight Cost Buckling failure 15 1936 - Plastics Use Expands Plexiglas 16 1942 - Composites- Fiberglass Cockpit components for war effort 17 1940’s – 1950’s Superalloys Before World War II iron based alloys were developed for high temperture work. The war increased demand of performance materials for turbochargers and jets. 18 1950-1963 - Titanium The A-12 precursor to the SR-71 19 1969 - Carbon Fiber Composites Rolls-Royce RB211 jet turbofan engine 20 1970 – Boron Fiber Composites F-14 Tomcat 21 1981 - Ceramics Space Shuttle Thermal Protection Tiles 22 1998 - Aluminum-Lithium 23 Space Shuttle external fuel tank 2005- GLARE “GLAss-Reinforced” Fiber Metal Laminate (FML) 24 2009 – Boeing 787 Dreamliner Large scale composite use 25 Future- Intelligent Materials Inbedded sensors and monitoring systems Materials change properties and configurations 26 Future- Nanotechnology Ultra-strength Composites Locally tailored materials for specific requirements 27 Summary 28 What is the brief history of the materials used to construct aircraft? Why were these materials adopted? What is the future for materials in aircraft?
