UNIT-I (8 Hours)
Aircraft materials Ferrous materials, nonferrous materials and alloys, ceramic materials and fiber reinforced composite materials, polymers, metal matrix particulate, Engineering Materials, Structural properties of materials, Atomic and lattice structure, bonding in Solids, Imperfections in crystals, Solid phase and phase diagrams, Furnishing Materials: Plastic, wood, plywood, glue, dopes and rubber used in aircraft manufacture. Paints, surface finishes and materials.
UNIT-II (9 Hours)
Properties and testing Isotropy, Orthotropic, True stress and strain, Strength and elasticity, Stiffness, Resistance, Plasticity, Ductility, Toughness and Hardness of materials, Concept of Fatigue and Creep, Mechanical Testing, Factors Affecting Strength, Deformation, Plasticity and Viscous elasticity, Fracture, Heat treatment, Chemical, thermal and technological Properties of testing and storage.
UNIT-III (8 Hours)
Specifications Indian Standard, British, American, French, German, and International specifications, Corrosion of material, its detection and prevention. Protective finishes, Testing Destructive and non- destructive testing techniques. Crack detection, inspection of parts by hot oil and chalk, dye-penetrate, fluorescent and magnetic particles, X-ray, ultrasonic, eddy current and acoustic emission methods.
UNIT-IV (9 Hours)
Non-destructive testing Importance of NDT in quality assurance. Different types of non-destructive techniques to obtain information regarding size, location and orientation of damage or cracks. Visual inspection techniques coin tapping technique for composite structures and adhesive bonds. Ultrasonic testing:
Pulse echo technique, pitch-catch technique, through transmission technique, A-scan B- Scan the methods of NDT and highlight its role in quality assurance. The emphasis should also be on its application during the process of design, manufacturing andmaintenance.
UNIT-V (8 Hours)
X-ray radiography Absorption spectra, short wave length, X-ray for detection of voids. Die penetration technique, Magnetic particle testing.
In each of the above techniques
- Theory and basic principles,
- advantages/disadvantages,
- material of parts that can be inspected,
- Physical size and shape limitation,
- economics of process,
- types of defects that can be detected,
- environment limitation are to be discussed along with equipment used for each of the techniques.
