Abstract
This study deals with the effect of complex material made from (Kevlar29, Honeycomb Aluminium and Carbon fibers) under high velocity is measured, also this material tested to specify the mechanical properties, then the high-impact loading utilizing the energy absorption tests were performed experimentally by using a gas gun device with shape of impactors flat cylindrical bullets. The discussion of the results of this work was termed under the failure of the coupling mode of the projectiles. The velocity level and defamatory affect the kinetic energy of the projectile. The thickness of the target has an impact on the projectile speed. The findings are discussed in terms of the work done to link the failure modes with the kinetic energy fall of the projectile and its effect on ballistic maximum velocity. The effect on the rate of the target thickness was then addressed. The vitality assimilation was anticipated by expecting that all out work done in the disfigurement of the plates is comparable to the total loss of the motor vitality of the shot. The connection between possible speed and the thickness of composite material was perceived. The hypothetical outcomes demonstrated great understanding contrasted and the test work.
Highlights
Several industries use honeycomb panels, because of their lightweight, high strength and light power consumption
The overall aim of this research is to study the response of new composite materials (Honeycomb Aluminium, Kevlar29 and Carbon fibers) and these were tested to specify the mechanical properties, the high-impact loading utilizing the energy absorption tests were executed experimentally by using a gas gun device with the shape of impactors flat cylindrical bullets
Form this work; it can be getting the following conclusions: 1. It was found this ballistic velocity experimental work composite material compared the behavior of the curve with energy and ballistic limit equation Abu Talib et al [10]
Summary
Several industries use honeycomb panels, because of their lightweight, high strength and light power consumption. Essam [2] On the other hand, aluminum alloys have long been preferred for civil and military aircraft due to their having high strength/weight ratio (lightweight), excellent weldability, the low value of thermal expansion coefficient and excellent corrosion and abrasion resistance. These properties of aluminum alloy attribute the rapid increase of using this alloy in automotive structural applications Essam [3]. Due to a high strain frequency, it is regulated by electromagnetic factors, force transmission, and increases in structural rigidity, intensity, and fracturing strength While such damage decreases the structure's load-bearing strength, its consequences can usually be predicted using the principles of fracture mechanics.
