Although largely geared toward the aerospace industry, this handbook assumes no prior knowledge about advanced composite materials and gradually makes the reader conversant in composite terminology. After giving a comprehensive description of what composites are and how they work, this guide breaks materials down into their constituents and offers details about design considerations and guidelines, various tooling concepts, manufacturing methods, and accepted repair theories and concepts. Other sections include the most up-to-date information on adhesive bonding technology, core materials, materials testing, and nondestructive inspection techniques and equipment.

This book covers the different aspects of tropical natural fibre composites in areas such as properties, design and analysis, manufacturing techniques, material selection of kenaf, oil palm, sugar palm, pineapple leaf, coconut, sugarcane and banana based fibre composites. Important properties such as mechanical and thermal of natural fibres as well their composites are presented. A study on the composite fibre-matrix interface is highlighted together with the design process and analysis of products from natural fibre composites. An overview on the manufacturing techniques (conventionally used to produce fibre glass fibre composites) such as pultrusion and filament winding is described to produce natural fibre composites. The importance of material selection system to obtain the most optimum materials for application in engineering components from natural fibre composites is covered with a strong focus on the concurrent engineering for natural fibre composites.

Whether an airplane or a space shuttle, a flying machine requires advanced materials to provide a strong, lightweight body and a powerful engine that functions at high temperature. The Aerospace Materials Handbook examines these materials, covering traditional superalloys as well as more recently developed light alloys. Capturing state-of-the-art developments in materials research for aeronautical and aerospace applications, this book provides a timely reference for both newcomers and veteran researchers in the field. The chapters address developments in bulk materials, coatings, traditional materials, and new materials. Beginning with an overview of superalloys, including nickel-, nickel–iron-, and cobalt-based superalloys, the text covers machining, laser cladding and alloying, corrosion performance, high-temperature oxidation, thermal spraying, and nanostructured coatings. It also includes four categories of composites used in aerospace: metal matrix, polymer, carbon nanotube-reinforced polymer, and self-healing composites. The text describes preparation, processing, and fatigue of lightweight magnesium alloys, as well as an exciting new class of materials—aerogels. This book brings readers to the cutting edge of research in materials for aerospace and aeronautics. It provides an entry point into this field and presents details to stimulate future research. This unique, up-to-date resource offers knowledge to enable practitioners to develop faster, more efficient, and more reliable air- and spacecraft.

Bonded Repair of Aircraft Structures

The conventional approach to through-life-support for aircraft structures can be divided into the following phases: (i) detection of defects, (ii) diagnosis of their nature and significance, (iii) forecasting future behaviour-prognosis, and (iv) pre scription and implementation of remedial measures including repairs. Considerable scientific effort has been devoted to developing the science and technology base for the first three phases. Of particular note is the development of fracture mechanics as a major analytical tool for metals, for predicting residual strength in the presence of cracks ( damage tolerance) and rate of crack propagation under service loading. Intensive effort is currently being devoted to developing similar approaches for fibre composite structures, particularly to assess damage tolerance and durability in the presence of delamination damage. Until recently there has been no major attempt to develop a science and tech nology base for the last phase, particularly with respect to the development of repairs. Approaches are required which will allow assessment of the type and magnitude of defects amenable to repair and the influence of the repair on the stress intensity factor (or some related parameter). Approaches are also required for the development and design of optimum repairs and for assessment of their durability.

Flame Hardening

This book intended for shop use tries to familiarize the reader with the peculiari ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.

"Lean Six Sigma ist sicherlich eines nicht: ein Qualitätsverbesserungsprogramm. Wenn Führungskräfte auf allen Ebenen und in allen Funktionen Lean Six Sigma verstehen, wird eine Transformation und Steigerung der Wettbewerbsfähigkeit des ganzen Unternehmens einsetzen. Quasi automatisch, Tag für Tag und Prozess für Prozess. Die gesammelten Verbesserungstechniken der letzten fünf Jahrzehnte werden dann Einsparungen erzielen - weit über den Erwartungen. Die profitabelste Investition in die Entwicklung unserer Mitarbeiter, die wir jemals gemacht haben. Dr. Wolfgang Schmitz, Corporate Continuous Improvement Director, Alcan Singen GmbH Das Buch führt in Lean Six Sigma ein und zeigt, wie Lean Six Sigma dazu beiträgt, dass Unternehmen in einer Welt erfolgreich sind, in der die Kunden hohe Qualität und kurze Lieferzeiten zu minimalen Kosten erwarten. Die ersten sechs Kapitel befassen sich mit den Grundsteinen von Lean Six Sigma: Sie führen in das Grundvokabular und die Grundkonzepte ein. Die übrigen Kapitel widmen sich der Anwendung von Lean Six Sigma: Nach Erläuterung der Lean-Werkzeuge wird anhand von Fallstudien aus der Praxis gezeigt, welche Konzepte und Methoden erfolgreich in Unternehmen angewandt wurden, um die Arbeitsumgebung zu verbessern und wie die Leser die Methode im eigenen Unternehmen einführen und umsetzen können.
