Ballistic protection using snow

, 2021
Small (5.56 mm, 7.62 mm and 9 mm) and medium (12.7 mm) arms rounds were fired at snow-filled 1.5m cubic gabions in a mid-winter condition in Fairbanks, Alaska. The rounds were excavated and penetration by each ammunition type was measured. A distribution

Ceramic Materials for Ballistic Protection

Key Engineering Materials, 2009
The ballistic performance of ceramic materials was investigated. Various types of ceramic-metals and ceramic-laminate composites were prepared. Their ballistic resistances against AP small arms ammunition of protection level 2 and 3 according to NATO Standardization Agreement STANAG 4569 were investigated.

Laminates for Ballistic Protection

1975
Abstract : Kevlar 29 and fiberglass laminates were ballistically evaluated with 9 mm projectiles to determine their ability to protect against severe hand gun threats. The Kevlar laminates exhibit an advantage over the glass laminates, providing complete protection against 9 mm projectiles up to 395 m/sec at an areal density of 7.3 kg/square meter. The

BALLISTIC MISSILES AND SPACECRAFTS PROTECTION

Авиакосмическое приборостроение, 2021
Попытки создания систем противоракетной обороны немедленно привели к созданию специалистами радиоэлектронной борьбы разнообразных комплексов средств противодействия ПРО (КПС ПРО). Стоимость этих комплексов составляет доли процента от стоимости систем ПРО, а их эффективность, за все годы существования противостоящих друг другу систем, оценивается как ...

Ballistic protection mechanisms in personal armour

Journal of Materials Science, 2001
High strength and high modulus fibres have revolutionised the design of lightweight armour, main fibre reinforced ballistic products are: ballistic helmets, vests, blankets and add-on car armour. Modelling of the ballistic properties of multi-layer fibre reinforced armour is still in the development stage, structural models that can be used to describe

Rusar microfilament yarn for ballistic protection

Fibre Chemistry, 2006
Technology was developed for fabrication of Rusar microfilament yarn with a linear density of 29.4 (300 filaments) and 58.8 tex (600 filaments) and textile armor with better strength properties than foreign analogs. The small diameter of the filaments combined with the chemical structure of the polymer allows the yarn to withstand important flexural ...
