Study Notes
Introduction
- Aircraft materials are crucial for construction and maintenance.
- Incorrect materials can lead to loss of life and equipment.
- Early aircraft used wood and fabric for construction.
- Steel tubing replaced wood for fuselage structure.
- Plywood became a key material in the 1920s for streamlined aircraft.
- World War II saw the rise of all-metal, stressed-skin construction.
- Modern aircraft use a diverse range of materials, including aluminum alloy, titanium alloy, Monel, stainless steel, and Chrome-molybdenum steel.
- Civilian aircraft primarily use aluminum alloy, while military aircraft often use titanium and stainless steel.
- Composite materials are increasingly used in aircraft construction.
Metals
- Metals are categorized as ferrous and nonferrous.
- Ferrous metals contain iron, including various types of steel.
- Non-ferrous metals are further categorized as lightweight or heavyweight, including aluminum, magnesium, titanium, and Monel.
- Titanium and its alloys are considered the heaviest lightweight materials in the aviation industry.
Properties of Metals
- Understanding metal properties is key for aircraft maintenance.
- Hardness: Ability to resist abrasion, penetration, cutting, or permanent distortion. Increased by cold working or heat treatment.
- Strength: Ability to resist deformation or stress without breaking. Varies depending on the type of load or stress applied.
- Density: Weight per unit volume. Cubic inch measurement is preferred in aircraft work.
Aircraft Materials - Ferrous
- Aircraft Materials Knowledge of materials, their uses, strengths, limitations, and other characteristics, is critical for aircraft construction and maintenance.
- Use of unsuitable materials can result in loss of life and equipment.
- Materials are vital to achieving quality in manufacturing.
- The development of new materials allowed the evolution of aircraft from wooden structures to modern composites.
- Modern aircraft use aluminum alloys, titanium alloys, Monel (nickel alloy), stainless steel, and Chrome-molybdenum steel.
- Civilian aircraft primarily use heat-treated aluminum alloys while military aircraft (fighters) use titanium and stainless steel.
- Composite materials are increasingly used for primary parts.
Properties of Metals
- Hardness refers to the ability of a material to resist abrasion, penetration, cutting, or permanent distortion.
- Strength is the ability of a material to resist deformation and to withstand stress without breaking.
- Density is the weight of a unit volume of a material, and it is generally expressed in pounds per cubic inch in aviation.
