Ballistic Behavior of Bioinspired Nacre-like Composites

open access: yesBiomimetics, 2023
In this paper, the ballistic performance of a multilayered composite inspired by the structural characteristics of nacre is numerically investigated using finite element (FE) simulations.

Impact response and ballistic performances of graphitic foams [PDF]

open access: yesWIT Transactions on the Built Environment, 2009
The demand for low weight structures that can achieve different structural, thermal and safety results is increasing in multiple engineering applications. Graphitic foam, due to its low density, relatively easy machine tooling, stiffness and homogeneity can be a good choice for sandwich panel filling. Moreover, in spite of its brittle general behaviour,

Polyimide aerogels for ballistic impact protection

open access: yesScientific Reports, 2022
The ballistic performance of edge-clamped monolithic polyimide aerogel blocks (12 mm thickness) has been studied through a series of impact tests using a helium-filled gas gun connected to a vacuum chamber and a spherical steel projectile (approximately ...

Comparison of Ballistic-Coefficient-Based Estimation Algorithms for Precise Tracking of a Re-Entry Vehicle and its Impact Point Prediction [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
This paper studies the problem of tracking a re-entry vehicle (RV) in order to predict its impact point on the ground. Re-entry target dynamics combined with super-high speed has a complex non-linearity due to ballistic coefficient variations.

Performance Evaluation of Ballistic Silicon Nanowire Transistors with Atomic-basis Dispersion Relations [PDF]

open access: yes, 2004
In this letter, we explore the bandstructure effects on the performance of ballistic silicon nanowire transistors (SNWTs). The energy dispersion relations for silicon nanowires are evaluated with an sp3d5s* tight binding model.

Investigation of the mechanical and ballistic properties of hybrid carbon/ aramid woven laminates

open access: yesDefence Technology, 2022
High-performance ballistic fibers, such as aramid fiber and ultra-high-molecular-weight polyethylene (UHMWPE), are commonly used in anti-ballistic structures due to their low density, high tensile strength and high specific modulus.

Alumina and low density polyethylene composite for ballistics applications

open access: yesJournal of Materials Research and Technology, 2021
The efficiency of alumina and low-density polyethylene (LDPE) composites in ballistic applications was investigated. Different concentrations of alumina were studied, 70, 75, 80, 85, 90 wt.%. The ballistic tests were carried out at subsonic speed using a
