“…A capacidade de penetração do projétil na placa de alumínio diminui com o aumento da dureza. Com o intuito de aumentar a dureza das placas de apoio, os tarugos foram submetidos a tratamento térmico [20]. Este tratamento constituiu em uma primeira etapa de solubilização seguida por uma etapa de envelhecimento visando obter dureza de aproximadamente 73 HB [21].…”

Resumo Alumina é comumente utilizada em blindagens compostas. Apresenta baixa tenacidade à fratura e esta propriedade está relacionada à resistência a múltiplos disparos. Com o intuito de melhorar a durabilidade em campo uma alternativa seria utilizar cerâmicas multicamadas. Neste estudo foi avaliado o desempenho balístico de estruturas multicamadas à base de alumina/epóxi e o efeito da adição de fibra de vidro como material de reforço. Os resultados foram comparados com placas de alumina individual de mesma espessura total que os sistemas multicamadas. O desempenho balístico dos painéis em mosaico de Al2O3/Al foi avaliado por meio de ensaio balístico DOP (depth of penetration) com projétil 7,62 mm perfurante. Os resultados indicaram que as placas individuais apresentaram melhor desempenho. No caso das estruturas Al2O3/epóxi, a resistência balística diminuiu com a redução da espessura das lâminas de alumina e com o aumento da camada de epóxi. A fibra de vidro não apresentou efeito significativo no desempenho.

“…Ubeyli et al [7] published a paper in 2008 about the "investigation on the ballistic behavior of Al2O3/Al2024 laminated composites". In this paper, the effects of mechanical properties of backing material and laminating type, as well as the adhesive type, on the ballistic performance of the composite armor were investigated.…”

Recently published research indicates that laminated composites have limited applications in advanced structural systems due to their low impact performance. The aim of this study is to give general information about the most commonly used materials and ballistic test methods to the new researchers who want to work on ballistic related subjects. In addition, to summarize the topics related to simulation methods such as FEM and numerical methods which are used most in ballistics. Finally, it is to enlighten them by giving suggestions to the researchers who will work on ballistics in the future.This review paper is focused on the impact resistance and penetration behavior of composites reinforced with fibers as well as their suitability for modern structural applications. The historical development of composite laminates is first reviewed in detail, and notable researchers and their contributions are then reviewed. Also included are reviews on published experimental, numerical, and analytical work on the low velocity impact of composite laminates. Relevant results will be discussed and the recommendations that need to be resolved in the future will be addressed.

“…Although they have the capability to decrease strike velocity, their brittleness resulted in the usage of backing materials [18][19][20]. Therefore, two factors lead the research to be grown in the composition of these materials: (i) the necessity of ceramic toughness and backing elasticity, (ii) the correlation between ceramic brittle deformation and energy absorption capability of backing lamination.…”

In this study, it was aimed to produce composite laminates of boronized AISI-1010 steel plates as an alternative protection against the threat level BR-2 defined in the EN-1063 standard. Cold rolled AISI-1010 steel plates were cut into hexagonal plates with 45 mm diagonals. These hexagonal plates were boronized by pack boronizing method at 950• C for 3 h. The characterization of the boronized samples was carried out by SEM-EDS, XRD, and Vickers microhardness measurement. Composite laminates having two different thicknesses were produced by bonding boronized AISI-1010 steel plates with a binary component acrylic adhesive and pressing. Armor plates were produced by combining hexagonal composite laminates together on a thin kevlar sheet to provide the necessary integrity. The ballistic tests of these plates were performed for the threat level BR-2 defined in the EN-1063 standard.K e y w o r d s : armor, laminated composite panel, ballistic damage, boronizing, iron boride
