“…Another headway lessening the importance of the control of a slanted defensive layer has been the presentation of pottery support in the seventies. At any particular district thickness, an aesthetic defensive layer is in like manner best when mounted more vertically, as keeping up comparable locale thickness requires the shield be reduced as it is slanted and the earth splits earlier as a consequence of its diminished conventional thickness [45][46][47][48][49][50][51].…”

This paper displays the discoveries of the scientists about the impacts of slanted protection in ballistic effect resistance. The rule favoured stance to ascertaining the cautious layer of a composite plate is that it assembles the Line-of-Sight (LOS) thickness of the plate. Another favoured viewpoint of having slanted fortification is that it has a much higher plausibility of diverting shots than a vertical plate of tantamount thickness.

These are: the impact of fragments and the impact of the shock wave. The most unfavourable situation is an under-vehicle explosion. Due to the small distance from the target (at the moment, the clearance in passenger off-road vehicles is approx. 0.3÷0.5 m), fragments hit the floor material, which is pre-loaded with the shock wave. Very frequently, in such types of cars, the personnel keep their legs directly on the floor and the seats are made of thin textiles.Requirements for the ballistic protection of cars should be considered in parallel with requirements concerning their mobility [15]. This necessitates the use of light materials for ballistic protection covers. On the other hand, such protections are usually required to perform the function of structural components, e.g. due to the manner of their installation, which is why the materials should be characterised by appropriate strength and rigidity. Modern materials for automotive applications, including ballistic covers for special cars, need to satisfy the requirements of multifunctionality and cost-effectiveness in the areas of production, operation, and disposal [9,10,11,25,29].The purpose of the study was to develop an additional, self-supporting ballistic cover for car bottoms, mounted on the outside to prevent the perforation of the base floor. In currently-used cars, the floor is usually made of ordinary steel sheets having a thickness of 1÷1.5 mm. Szudrowicz M.

“…Hybrid composites normally consist of one high modulus and priced fibers such as carbon fibers, which provide stiffness and load bearing characteristics; while the second is low modulus and low cost like E-glass fibers which provide damage tolerance. Furthermore, stacking configurations and volume fraction of various layers can vary the mechanical characteristic of any hybrid composites materials [3][4][5].…”

In this study two groups of hybrid composite materials were experimentally studied in static uniaxial compression test. The first group consisted of Kevlar/glass fiber and the second group consisted of carbon/glass fiber reinforced epoxy resin. Each group contained four subsets (A, B, C and D) of hybrid composite materials. Compression test was carried out according to ASTM D695 and each test was replicated five times. It was observed that for the same type of hybrid composites, placing carbon or Kevlar fiber layers at the top and bottom; and glass fiber layers in the middle did not give significant effects than placing glass fiber layers at the top and bottom and carbon or Kevlar fiber layers in the middle of the specimens under compressive test. Furthermore, the results showed that hybrid composite laminates for the same number of layers with carbon/glass fiber provided the highest amount of the compressive stress value up to 40% compared to the results of the group which was reinforced with Kevlar/glass fiber.
