“…These materials show similar strength parameters and much lower density, compared to steel components. Heavy steel helmets and vests, which negatively affected soldiers' mobility, were replaced by lightweight and thin ballistic composite materials providing comparable protection against combat agents [4][5][6]. In the defense industry, hybridization of reinforcement is used to reduce the cost of armor production.…”

This paper presents the influence of the type and structure of reinforcement, on the epoxy resin matrix polymer composites mechanical and ballistic properties. Aramid, basalt, glass fabrics and their hybrid systems were used as reinforcement. Impact strength according to Izod and "falling arrowhead", flexural strength and structure of the obtained composites were tested. The specific gravity was also determined. The aramid-glass hybrid composites showed high flexural strength (397 MPa) and Young's modulus (21 GPa). However, aramid-basalt composites had high impact strength (116 kJ/m2) and impact energy absorption (45 J).

“…Glass fibers are the more popular choice due to their lower cost and most availability. [3][4][5] High-velocity impacts can cause substantial damage to various structures, including military vehicles and civilian infrastructure. To enhance the performance of these structures, it is important to comprehend the energy absorption capabilities of different materials under high-velocity impact conditions.…”

Composite laminates have found extensive application in various industries, and numerous studies have been conducted to investigate their behavior in flat sheet configurations. The present study aims to extend this research by examining the behavior of convex composite specimens subjected to high velocity impact (HVI), and comparing their energy absorption and failure area to that of flat sheets made of glass fibers. Additionally, we seek to investigate the influence of curvature diameter on the energy absorption and fiber failure percentage of the composite specimens. Four series of composite laminates with distinct geometries, comprising a flat specimen and three convex composite specimens, were fabricated with nine layers each and diameters of 10, 15, and 20 cm. All specimens were fully clamped and subjected to empirical gas gun impact tests at three different velocities of 200, 250, and 300 m/s. The velocity values before and after the impact were measured using velocity sensors, and the energy absorption of the laminates was computed. Of the tested composite specimens, those with smaller diameters and greater curvature exhibited reduced fiber damage percentage and increased energy absorption. Compared to the flat specimens made of glass fibers, the convex specimens with a diameter of 10 cm exhibited an energy absorption increase of approximately 47%, while the specimens with diameters of 15 and 20 cm showed approximately energy absorption increases of 42% and 7%, respectively. The results were confirmed through simulation using finite element software ABAQUS/Explicit.Highlights Curved E‐glass laminates studied under high velocity impact which is done experimentally and numerically. Convexity increases energy absorption capacity of E‐glass reinforced epoxy composites. The results show that convexity can absorb more energy compared to flat panels. The damaged area of curved laminates are smaller than the flat one. The findings suggest that convexity can be a useful design feature for improving impact resistance in various applications.

“…However, due to the associated heavy weights and corrosion problems, it is necessary to develop improved new solutions with the same levels of protection but with less weight. The continuous evolution of the materials, with a special focus on composite materials, allows for the development of better combinations of materials in order to get lightweight solutions without penalizing the ballistic protection levels [5][6][7][8].…”

This paper investigates the fragment performance of several composite panels for attaching to the inside walls of a building structure. These panels were developed using different types of fiber woven fabrics (W0, W90) combined with distinct layers orientations (angle-ply effect) of L0/0 and L0/15. Aramid, E-glass, and S-glass fiber fabrics impregnated with thermosetting epoxy resin, and a prepreg of Ultra High Molecular Weight Polyethylene (HB24) were employed. The panels are subjected to ballistic impact using different fragments under impact velocities in the range of 120 to 420 m/s. In order to measure the energy absorbed by the ballistic panels, the impact velocity and the residual velocity of the fragment were measured with laser chronographs placed before and after the laminated test specimens. The paper demonstrates quantitatively that the angle-ply laminates produced using L0/15 woven fabric orientation presented a higher impact energy absorption, promoting higher reductions on the fragment residual velocity compared to the L0/0 orientations. The laminates produced using UHMWPE fibers (HB24) presented better ballistic properties compared to the other fibers. Furthermore, it was noted that the energy dissipation rate is linearly correlated with the impact velocity and is independent of the fragment geometry.
