2. Introduction
• Polyamides
• Di-amines & di-carboxylic acids
• DuPont Company
• Condensation polymerization
• Nylon types(6.6,6,6.7,6.10,6.12 etc.)
• Zytal(DuPont), Ultramide(BASF)
Capron(Allied Signal), Durethan

3. Physical Properties
• Large influence of functional group
• Crystallinity increases
• High melting(190-350°C)temperature
• Tensile strength (90-185Nm/mm2)
• Density (113.135g/cm3)
• Water absorbance
• Chemically resistant

4. Processing Technique
• Injection molding
• Limitations
1. moisture absorbent
2. Effect of sunlight
• Applications
• Textiles
• Automotive
• Furniture

5. Research Articles
1)Recycled nylon fibers as cement mortar reinforcement
• Fishing nets was recycled and used as tensile reinforcement.
• Alkali resistant, no adverse impacts, crack resistant( +35%)
• Compressive strength increases (+75%)
(Figure.1)

6. Research Articles
2 ) Nylon composite propellers for aircrafts
• Nylon-6 and Montmorillonite hybrid was made
• HDT, strength increases, water absorption reduced (40%)
• Light weight
(Figure.2)

7. Conclusion
Necessity is the mother of invention
