An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance. As the name suggests ...

Sep 21, 2023 · An EFP is a copper warhead that, once detonated, is superheated, turning it into a molten projectile that can punch through almost anything — including M1 Abrams tanks and MRAPs. They are...

The formation behavior of coated reactive explosively formed projectiles (EFP) is studied by the combination of experiments and simulations. The results show that the coated EFP can be obtained by explosively crushing the double-layer liners, and ...

Initial MEFP warhead concepts utilized a steel case, LX-14 explosive billet and a tantalum, iron or copper liner embossed or formed to produce the individual penetrators. A MEFP liner is basically a conventional EFP liner that produces a shotgun like spray of compact fragments.

Nov 2, 2019 · The Combat Capabilities Development Command Armaments Center (CCDC AC) characterized the performance of a simple, improvised device found in a foreign theater. This article outlines the effort to characterize the penetration performance of three improvised, copper, 4-inch-diameter EFPs recovered from the field.

Jun 1, 2014 · Explosively formed penetrators (EFPs) have been used in a number of munition systems to defeat armor, masonry and concrete targets. EFPs are launched from considerable distance from their targets.

In this study, the formation mechanism of an explosively formed penetrator (EFP) with tail fins was analyzed. Through static denotation and dynamic flight tests, the feasibility of using a step-shaped liner during the formation of an EFP with tail fins was verified.

Copper liners designed for use in EFP (E xplosively F ormed P rojectile) or shaped charge assemblies. The copper liners area available in the following diameters and types:

An improvised Explosively-Formed-Projectile (EFP), sometimes called a penetrator, is a self-forging Misnay-Schardin (MS) Shaped-Charge (SC) warhead, or a Self-Forging-Fragment …

Jan 21, 2022 · Copper EFP’s forming characteristics are analyzed in the numerical simulation to obtain the stress and strain conditions in forming of EFP under explosive loading. The maximum von Mises stress can be as much as 604 MPa, while the …
