PROTECTIVE TEXTILE
Contents:
• Introduction
• Ballistic Protective Textiles
• Principle Of Ballistic Protection
• Types of Armor
• Conclusion
Introduction
Nowadays safety and Protective textiles have become an integral part in one or other form. Safety and Protective textiles refer to garments and other fabric related items designed to protect the wearer from harsh environmental effects that may result in injury or death.
Industrial textiles are used to protect from one or more of the following:
• Extreme heat and fire
• Harmful chemicals and gases
• Bacterial environment
• Mechanical hazards(e.g.; bullets)
• Radiations(e.g.; UV radiations)
Ballistic Protection
Requirements for Ballistic protection
• Minimum weight with maximum personal
mobility.
• Maximum protection.
• Energy absorption characteristics of the
material.
Principle Of Ballistic Protection
Fibres and Fabrics used for
Ballistic Protection
• P-aramid fibres (Kevlar)
• Ultra high modulus polyethylene
• Carbon fibres
• Ceramics
• Spider silk
Common Properties:
• High impact resistance
• Good dynamic energy absorption capacity
• Good chemical resistance
• High specific strength and modulus
• Service life near to 100 years
• Fatigue resistance
• Strain is spread over a much larger area
Types of Armor:
• Soft Armor
• Hard Armor
Characteristics & Manufacturing Methods of
Soft Armor
Characteristics:
For resistance to low velocity bullet
Efficient only for low weight per square meter
Constructed from multiple layers varying b/w 10-50 of woven fabrics sewn together with crosswise weave.
Manufacturing methods:
Multi layers(20-30) stitched together using Kevlar or UHMPE threads.
For High Velocity 10 layers of Kevlar 49 plies for velocity range of 200-900 mps
Inner layer of Kevlar and outer layer composed of Kevlar, spectra shield stitched together.
Characteristics & Manufacturing Methods
Of Hard Armor
Characteristics: For resistance to high velocity bullets
Multi layer fabrics combined together with a resin binder
More efficient at wt.> 10kg/m2.
Less dependence of weave construction.
Manufacturing:
JACKAL STEEL-medium carbon & low chromium molybdenum type steel.
