A Refined Quasi-microstructure Model for Finite Element The nondelamination characteristics of three-dimensional (3-D) braided composites under ballistic impact makes them possess considerable potential in ballistic protection applications. However, there are only a few references concerning the calculation of ballistic properties of these composites, and all are based on the continuum assumption of
MPa . Polymer composites reinforced with sisal fibers reach Charpy impact energy over 149.0 J/m. Wambua et al  were probably the first to conduct a systematic investigation on the ballistic properties of natural fiber reinforced polymer composites. These were
Analysis of the Fragmentation of AlON and Spinel Under a glass-polymer laminate. Magnesium aluminate spinel (MgAl 2O 4) and AlON are promis-ing candidate materials for application as a hard front layer in transparent armor. Com-prehensive, systematic investigations of the fragmentation of ceramics have shown that the mode of fragmentation is one of the key parameters inuencing the ballistic

Local Deformation and Failure Mechanisms of Polymer Bonded Jan 29, 2016 · The dynamic multi-scale deformation mechanism of polymer bonded energetic material is investigated. Samples made of polymer bonded sugar (a known simulate for polymer bonded explosives) with 85 % sugar crystals and 15 % polymer binder are used. The samples are dynamically compressed using a split Hopkinson pressure bar. Using a high magnification, meso-scale 2D digital
Experimental and Analytical Characterization of the Macromechanical Response for Triaxial Braided Composite Materials Increasingly, carbon composite structures are being used in aerospace applications. Their highstrength, high-stiffness, and low-weight properties make them good candidates for replacing many aerospace structures currently made of aluminum or steel.
On the ballistic impact response of microbraid reinforced Mar 01, 2016 · The ballistic limit of the braided composites were above 195 m/s and 207 m/s when impacted with flat cylinders and blade-like projectiles, respectively. Triaxial braided composites showed a higher ballistic limit and smaller damaged area with respect to satin woven composites having approximately the same areal density and fibre volume fraction, when tested under the same impact
The role of adhesive in the ballistic/structural Oct 01, 2012 · This investigation is aimed at assessing both the ballistic-penetration and the mechanical-durability performance of various hybrid-armor configurations. While this investigation is in its earliest phase, the preliminary results confirmed the fact that the there is a trade off in the performance of the adhesive under dynamic and fatigue-loading
Nov 01, 2010 · A polymer-bonded sugar (PBS) (or sugar mock) is a particulate composite material in which sugar rather than explosive crystals are mixed into a polymer binder. PBSs allow safe investigation of the effect of various parameters, such as particle size
The use of digital speckle radiography to study the The model system consisted of a polymer-bonded sugar (PBS) (otherwise known as a sugarmock) confined between two mild steel plates. The DSR technique relies upon creating a layer within the specimen that is seeded with lead particles.Kovove materialy - Metallic MaterialsBallistic investigation of polymer bonded borided steel sheets GENCER, Y., TARAKCI, M., ALANKAYA, V., AZAKLI, Y., CENGIZ, S., GULEC, A.
