The Effects of Stacking Sequence Layers of Hybrid Composite Materials in Energy Absorption under the High Velocity Ballistic Impact Conditions – An Experimental Investigation

Abstract

In the current study, the effects of stacking sequence layers of hybrid composite materials on ballistic energy absorption, which were fabricated from Kevlar, carbon, glass fibres and resin have been experimentally investigated at the high velocity ballistic impact conditions. All the samples have equal mass, shape and density, but they have different stacking sequence layers. After running the ballistic test in the same conditions, the final velocities of the bullets showed that how much energy absorbed by the samples. The energy absorption of each sample through the ballistic impact has been calculated, accordingly , the decent ballistic impact resistance materials could be found by conducting the test. This paper can be further studied in order to characterise the material properties.

Hybrid Composite Laminates Reinforced with Kevlar/Carbon/Glass Woven Fabrics for Ballistic Impact Testing

“…An object (singular) is often described as having a coefficient of restitution as if it were an intrinsic property without reference to a second object. In this case, the definition is assumed to be with respect to strikes with a perfectly rigid and elastic object [ 16 – 18 ] …”

“…Composite structures for military ground vehicles, on the other hand, are designed to absorb multiple high-energy impacts but have much less dimensional restrictions. Since softer materials tend to dissipate more energy during impact, a low modulus/high strength alternative would be well suited for backing panel composites [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

“…The material properties of FGMs are assumed to be temperature dependent. Numerical results demonstrate that both buckling temperature and thermal postbuckling strength of the FGM shells increase with increase in foundation stiffness, Figure 2 shows the details [10][11][12][13][14][15][16]. Duc and Cong [17,23] proposed an analytical investigation on the postbuckling behaviors of thick symmetric functionally graded plates resting on elastic foundations and subjected to thermomechanical loads in thermal environments as shown in Figure 3.…”

“…FGMs also permit tailoring of material compositions to optimize a desired characteristic such as to minimize the maximum deflection for a given load and boundary conditions, or maximize the first frequency of free vibration, or minimize the maximum principal tensile stress. As a result, FGMs have gained potential applications in a wide variety of engineering components or systems, which include armor plating, heat engine components and human implants [13,36]. The variations of material properties in an FGM are usually achieved by continuously varying volume fractions of the constituent materials.…”

“…Most of scientific works analyze the impact behavior of a single material, but only a few papers study the combination of different materials [ 18 , 19 , 20 ]. Aktaş et al [ 18 ] analyzed six configurations of woven/knit fabric glass/epoxy hybrid composites.…”
