Experimental Research on Lethal Range for 122 mm Carbon Fiber Warhead

Abstract

A composite material is a combination of two materials with different physical and chemical properties. The main features of composite materials are durability is much greater than metals, easy to form for complex shapes, good resistance to chemicals and atmospheric factors and low thermal conductivity compared to minerals. In line with the development of the world and the technological progress in materials science and its properties, the idea of improving efficiency of warheads has emerged by finding alternatives materials to used in the manufacturing the outer body of warheads. In order to evaluate the lethal range two types of warhead confinement with preformed fragments were researched by means of experiment, this warheads body consists of composite casings Carbon Fiber and Kevler/Carbon Fiber (50/50%), balls fragments and high explosive. Experimental results show that the lethal range of charge with composite shell is higher than that of charge with steel shell by 10 to 12.5% and weight decreased by 11.5 %.
