Penetration dynamics of AP8 in thin ceramic tiles

The interaction of thin ceramic tiles with AP8 (WC core, 7,62 mm) at 1000 m/s velocity has been studied experimentally and numerically. “Thin” ceramic tiles refers here to ratio of the tile thickness (t) to the projectile diameter, (d), t/d@ 1, as they are both in the same order. The method applied to visualize the penetration dynamics has been...

Ballistic performance and microstructure of four armor ceramics

The ballistic behavior of four different armor ceramic materials with thicknesses varying from 3 mm to 14 mm has been investigated. These are two types of alumina Al2O3 armor grades and two types of SiC armor grades produced by different armor ceramic producers. The ballistic study has been performed using the standard DoP technique with two...

PELE fragmentation dynamics

An analytical model that describes the PELE fragmentation dynamics is presented and compared with experimental results from literature. The model accounts for strong shock effects and detailed interactions taking place between the filling – the inner core of the ammunition – and the target (including shock wave, expansion wave, free surface and...

Fluorocarbon coatings deposited on micron-sized particles by atmospheric PECVD

Fluorocarbon coatings have been deposited on micron-sized silica particles by means of atmospheric pressure plasma-enhanced chemical vapor deposition (PECVD). The silica particles have a diameter in the range between 40 and 70 ?m. They are fluidized at atmospheric pressure in a circulating fluidized bed combined with a dielectric barrier...

Time resolved engineering metal penetration models

Current tools describing behavior of ballistic materials under impact seem to be less suitable to assist armor developers in their efforts. They are insufficiently detailed or need comprehensive material properties and material failure description, unavailable in the initial stages of the development of new solutions. Therefore TNO is building a...

Particle coating – a novel trend in energetic materials engineering

The development of new energetic materials with enhanced blast properties requires better understanding of factors as particle type, size and particle/matrix distribution. The ability of growing a coating on particles opens new possibilities in energetic materials engineering. Functionalities as ingredient compatibility, increased burning rates...

Modification and characterization of (energetic) nanomaterials

Nanomaterials are a topic of increased interest, since they have properties which differ from their macroscopic counterparts. Many applications nowadays take advantage of the new functionalities which natural and manufactured nanoparticles possess. Based on these developments, also the research on energetic nanomaterials is receiving more and...
