Application of Composite Materials for different mechanical components

  1. 1. Application of Composite materials for different mechanical components Piyush Mishra (BE-Mechanical) Sinhgad College of Engineering, Vadgaon(Bk.),Pune
  2. 2. Inspiration from mother nature LIGHT-WEIGHT FLEXIBILTY ROBUSTNESS STRENGTH STIFFNESS TOUGHNESS CORROSION RESISTANCE FATIGUE LIFE WEAR RESISTANCE FATIGUE LIFETAILORABLE REDUCED WEIGHT ATTRACTIVENESS
  3. 3. Composite materials Wood Cellulose fibers bound by lignin matrix Bones Stiff mineral “fibers” in a soft organic matrix permeated with holes filled with liquids Granite Granular composite of quartz, feldspar, and mica Two or more chemically different constituents combined macroscopically to yield a useful material.
  4. 4. Man-made composites Concrete Plywood Tyre Fiberglass
  5. 5. Definition: • A material which is composed of two or more materials at a microscopic scale and have chemically distinct phases. • Heterogeneous at a microscopic scale but statistically homogeneous at macroscopic scale. • Constituent materials have significantly different properties. • Conditions for a material to qualify as a composite: 1. Combination of materials should result in significant property changes. 2. Content of the constituents is generally more than 10 % 3. In general, property of one constituent is much greater ( ≥ 5 times) than the other.
  6. 6. Anatomy of composite materials Re-inforcement: discontinuous ,stronger ,harder Matrix: Continuous
  7. 7. Anatomy of composite materials What are the functions of reinforcement? 1. Contribute desired properties 2. Load carrying 3. Transfer the strength to matrix What are the functions of a matrix? 1. Holds the fibres together 2. Protects the fibres from environment 3. Protects the fibres from abrasion (with each other) 4. Helps to maintain the distribution of fibres 5. Distributes the loads evenly between fibres
  8. 8. Classification Composites Random Orientation Preferred Orientation Particulate Fibrous Single Layer Multi-layer Continuous & Long fibres Discontinuous & short fibres Hybrid LaminateLaminate
  9. 9. • High beam stiffness • High torsional stiffness • Low density • Good fatigue resistance Tailoring the elastic properties via control of the fibre architecture Problem arises due to combined forward & rotational motion Necessary torsional stiffness Beam strength Helicopter Rotor Blade
  10. 10. Composite Pressure Vessels The project was launched in partnership with M/s. Kineco Pvt. Ltd., Panaji and with technology support from IIT-Bombay. The project aimed at developing filament wound pressure vessels for the following applications. 1. Undercarriage FRP tanks (450 mm diameter with 2.00 bar operating pressure to be fitted to the railway passenger coaches for water supply to the toilets ). 2. Two sizes of pressure vessels (500 mm & 600 mm diameter) for water treatment application; operating pressure : 3.50 bar.
  11. 11. The project was launched in partnership with M/s. Supal FRP Pvt. Ltd, Hyderabad with design inputs from the Industrial Design Centre (IDC) of IIT-Bombay. For DG sets of capacities of 15 KVA & 100 KVA to meet 25 dB noise attenuation levels as prescribed by Environment (Protection) Act, 1986. The enclosure was supplied to M/s Kirloskar Oil Engines Ltd., Pune for testing and its performance was found quite satisfactory. The composite enclosure offers resistance to corrosion and provide high internal damping & low noise transmission. Composite modular acoustic enclosures
  12. 12. Composite Artificial Limbs for Physically Handicapped The project was lunched in collaboration with M/s. Mohana Orthotics & Prosthetic Centre, Chennai and technology support from Madras Institute of Technology (MIT), Chennai. Below-knee endoskeleton type artificial limbs are lighter in weight and better appearance than ever before with improved gait for the patients. The limb consists of the following parts: 1. a FRP tubular structure, 2. top & bottom connectors, 3. PU foot with composite keel embedded in it and 4. a polypropylene socket to accommodate the amputee stump. Such indigenously developed below-knee artificial limb is cheaper than the important ones.
