Manufacturing Technology for Aerospace Structural Materials
Format: PDF / Kindle (mobi) / ePub
The rapidly-expanding aerospace industry is a prime developer and user of advanced metallic and composite materials in its many products. This book concentrates on the manufacturing technology necessary to fabricate and assemble these materials into useful and effective structural components.
Detailed chapters are dedicated to each key metal or alloy used in the industry, including aluminum, magnesium, beryllium, titanium, high strength steels, and superalloys. In addition the book deals with composites, adhesive bonding and presents the essentials of structural assembly.
This book will be an important resource for all those involved in aerospace design and construction, materials science and engineering, as well as for metallurgists and those working in related sectors such as the automotive and mass transport industries.
Flake Campbell Jr has over thirty seven years experience in the aerospace industry and is currently Senior Technical Fellow at the Boeing Phantom Works in Missouri, USA.

classified as being fusion weldable, while the Al–Cu–Mg alloys of the 2XXX series and the Al–Zn– Mg–Cu alloys of the 7XXX series are generally higher strength but are not fusion weldable. In reality, except for a limited number of the 2XXX alloys that are used for welded fuel tanks for launch vehicles, aluminum welded structure is not widely used for aerospace structures. However, as friction stir welding technology matures, this situation could change in the future. The process of strengthening

heat and pressure. 4.7 Superplastic Forming The advantages of superplastic forming include the ability to make part shapes not possible with conventional forming, reduced forming stresses, improved formability with essentially no springback and reduced machining costs. The mechanism of superplasticity was covered in Chapter 2 on Aluminum. In general, titanium alloys exhibit much higher superplastic elongations than aluminum alloys, and there are a much wider variety of titanium alloys that

found applications in aerospace for thermal protection systems. Carbon–carbon composites are the oldest and most mature of the ceramic matrix composites. They were developed in the 1950s for use as rocket motor casings, heat shields, leading edges and thermal protection. The most recognized application is the Space Shuttle leading edges. For high temperature applications, carbon–carbon composites offer exceptional thermal stability, provided they are protected with oxidation resistant coatings.
