Animal skin, wooden and metal shields.

Front

What was the development in body armor during the 1940s?

Back

Nylon-based flack jackets.

Front

What are the two categories of body armor?

Back

Soft panel and hard panel.

Front

What is a ballistic protection garment?

Back

A textile-based material designed to slow down and reduce the penetration of projectiles.

Front

What are the main causes of military casualties due to ballistic projectiles?

Back

High speed ballistic projectiles caused by fragmenting devices like grenades, mortars, and artillery shells.

Front

What is the range of bullet sizes mentioned in the text?

Back

4 mm to 12.7 mm in diameter.

Front

What are the essential properties of fibers used in ballistic fabrics?

Back

High tenacity, high modulus, low density, high energy absorption capability, excellent resistance to water and chemicals.

Front

What types of fibers are used in ballistic fabrics?

Back

Para aramid fibers (e.g., Kevlar), ultra high molecular weight polyethylene (e.g., Dyneema), ballistic nylon, and mineral/inorganic fibers.

Front

What is the advantage of unidirectional (UD) fabrics in ballistic applications?

Back

They provide a high modulus structure with low resin content, allowing flexibility.

Front

What is the significance of stitching in ballistic fabrics?

Back

Stitching improves ballistic performance by increasing inter-yarn friction and preventing yarn pull-out.
