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.

Recent Trends in Ballistic Protection

Textiles and Light Industrial Science and Technology, 2014
There has been a tremendous improvement in the design of ballistic protective materials, which have been in use from time immemorial. Developments in the technology of manufacturing high performance fibres and production processes have enabled the production of light weight body armour with improved protection levels.

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 ...

Materials for protection from ballistic injury

Fibre Chemistry, 1996
It was noted that stiff-chain (para-aramid) and flexible chain (polyethylene) high-strength, high-modulus polymer fibres have been successfully used for ballistic protection of humans. It was hypothesized that new high-strength, high-modulus fibres based on aromatic polyesters could be successfully used for this purpose in the very near future.

Development of Composite Structures for Ballistic Protection

Materials Science Forum, 2007
The mechanical behaviour and ballistic performance of carbon, glass (E and S type), aramide and polyethylene fabric reinforced composites with different epoxy resins were studied. The specimens −produced by hand lay-up method− were qualified by low velocity (Charpy and drop weight tests) and high velocity (two different bores ballistic) impact tests ...
