Ceramic–polymer composites for ballistic protection

Advances in Applied Ceramics, 2006
Armour systems require advanced solutions, relying on a combination of materials of different natures to provide adequate ballistic protection and weight saving. For the first time in the present study composite layered systems based on monolithic armour ceramic tiles joined with polymer infiltrated ceramic foams have been designed and evaluated for ...

Ballistic protection using snow

International Journal of Impact Engineering, 2022
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 and average of penetration depth was determined.

Ballistic Studies in Eye Protection

American Journal of Ophthalmology, 1964
Abstract : This work was undertaken to evaluate ballistically the resistance to penetration of optical lenses and rabbit eyes by lead and steel BB's. Plastic CR39 lenses were tested, in addition to several types of glass lenses. On the basis of the evaluations, it was concluded that: the plastic lenses were the most resistant to both missiles.

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

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.

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 ...

Thermal protection of ballistic entry vehicles

Journal of Spacecraft and Rockets, 1965
The concepts of radiation cooling and ablation cooling using char-forming plastic materials are examined for the purpose of providing thermal protection for ballistic vehicles entering the earth's atmosphere from near earth orbits. The effect on thermal protection requirements of re-entry from various orbit altitudes is presented.

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
