Definitions

  • the present invention relates to a composite panel for protection against projectiles, splinters, etc., the panel being primarily arranged to supplement the outer shell or carapace of the vehicle, etc. so that the overall protection against projectiles, splinters, etc. is considerably increased without the weight of the vehicle or the like being correspondingly increased.
  • LTV light tank vehicles
  • the object of the present invention is to propose a safety panel that, in relation to its light natural weight, provides extraordinarily high protective levels against projectiles, splinters, etc.
  • a protective panel according to the present invention are shown in greater detail in Fig. 1, and are including a large number of layers or strata of woven material of, for example, the aramide fibre type with different densities, these layers being laid mutually offset and in mutually different directions.
  • these layers which have been given reference numerals 2-7 in Fig.
  • the protective panel according to Fig. 1 further includes surface layers 1a, 1b, which preferably consists of a suitable elastically resilient material, for example heavy-duty rubber of the industrial type.
  • the protective panel according to the present invention may, as is schematically intimated in Fig. 2, be secured against the inside of the sheet metal of, for example, a vehicle with the aid of, for instance, Velcro tape 8 or other suitable anchorage devices, secured against the one surface layer of the protective panel.
  • Fig. 4 shows an LTV composed of a number of panel sections, these panel sections being each advantageously provided with a protective panel according to the present invention.
  • the above-mentioned protective panel according to Fig. 1 may also be applied to the outer sheet metal 12 of a vehicle - see Fig. 3 - with the aid, for example, of two bent plates 13 and 14, in which event shock-absorbing material 9, 10 of resiliently yieldable type such as rubber, springs, etc., and optionally an aluminium sheet 11 may also advantageously be disposed between the outer sheet casing 12 of the vehicle and the protective panel proper, to further improving the protective effect of the protective panel on site.
  • a protective panel that comprises plies of 6 mm vinyl, it being apparent that the limit velocity for this material combination is approximately 360 m/s at a surface weight of approximately 6 kg/m2.
  • Point "b” shows a protective panel that comprises glass in three layers with a thickness of 8.5 mm, it being apparent that the weight is more than three times greater than for protective panel "b", even though the limit velocity is slightly lower than for protective panel "a”.
  • a protective panel which consists of glass in three layers of a thickness of 11 mm
  • a protective panel which consists of plies including Kevlar with steel inlays in plastic of 15 mm and the panel of the vehicle consisted of plastic with spacer material of aluminium of 43.3 spacing
  • the protective panel consisted of glass fibre of 32 mm spacing
  • a protective panel which consisted of plies including Kevlar of a spacing of 28 mm
  • at "g” is shown the limit velocity of a safety vest as a function of its weight and the values of this safety vest have been selected to constitute a reference level
  • at "h” is disclosed a protective panel, which consists of 6 mm ply fabric including Kevlar
  • at "i” is disclosed a cover, which consists of aluminium and 6.3 mm plies including Kevlar
  • a protective panel which consists of plies including Kevlar of 3 layers at a spacing of
  • protective panel 1A see point 1A in Fig. 6 with the lowest limit velocity - use was made, together with a certain vehicle panel designated Bv FMV 5, of an aramide fibre panel with rubber coatings according to Fig. 1, of a surface weight of 6 kg/m2 (16 fabrics or layers), with the fibre fabrics vulcanized or cured and the protective panels were formed with the aid of a press during provision of heat and after cooling. This resulted in a limit velocity of approximately 500 m/s at a surface weight of approximately 17 kg/m2.
  • protective panel 1A1B As protective panel 1A1B according to the present invention - see that point that is marked 1A1B in Fig. 6 - use was made, together with a certain vehicle panel entitled Bv FMV 5, of an aramide fibre panel with a rubber matrix according to Fig. 1, of two surface weights of which one is 6 kg/m2 (16 fabrics of layers), and the other is 7 kg/m2 (19 fabrics or layers), with the fibre fabrics vulcanized or cured and the protective panels were formed with the aid of a press during provision of heat and after cooling.
  • protective panel IIA As protective panel IIA according to the present invention - see that point that is marked with IIA in Fig. 6 - use was made, together with a certain vehicle panel entitled Bv FMV 5, of an aramide fibre panel with a polyethylene matrix according to Fig. 1 of a surface weight of 6 kg/m2 (18 fabrics or layers), with the fibre fabrics and polyethylene film overlaid with one another and the protective panels were formed with the aid of a press during provision of heat and after cooling. This resulted in a limit velocity of approximately 750 m/s at a surface weight of approximately 17.5 kg/m2.
  • protective panel IIB As protective panel IIB according to the present invention - see that point which is marked IIB in Fig. 6 - use was made, together with a certain vehicle panel entitled Bv FMV 8, of an aramide fibre panel with a polyethylene matrix according to Fig. 1 of a surface weight of 7 kg/m2 (21 fibres or layers) with fibre layers and polyethylene film overlaid on one another and formed with the aid of a press during provision of heat and after cooling. This resulted in a limit velocity of approximately 800 m/s at a surface weight of approx. 18 kg/m2.
  • protective panel IIIA see that point that is marked IIIA in Fig. 6 - use was made, together with a certain vehicle panel entitled Bv FMV 7, of a polyethylene fibre panel with a polyethylene matrix according to Fig. 1 of a surface weight of 6 kg/m2 (35 fabrics or layers), and a surface weight of 7 kg/m2 (40 fabrics or layers) with the fibre fabrics and polyethylene film overlay one another and the protective panels formed with the aid of a press during provision of heat and after cooling. This resulted in a limit velocity of approximately 750 m/s at a surface weight of approx. 17.5 kg/m2.
  • Fig. 5 shows the limit velocity in metres per second as a function of the surface weight in kilograms per square metre for different materials and combinations of materials on target shooting with a cylindrical splinter of 3.6 g.
  • point "a" is disclosed a selected reference level and this also relates to a safety vest in this case.
  • point “b” is indicated the surface weight and limit velocity for 3 mm steel
  • point “c” is disclosed surface weight and limit velocity for aluminium of 11 mm thickness
  • point “d” is disclosed surface weight and limit velocity for a panel consisting of aluminium, plies including Kevlar, acrylonitryl, acrylic glass of 24.5 mm
  • point “e” is disclosed surface weight and limit velocity for a panel consisting of glass fibre and acrylonitryl
  • point “f” is disclosed surface weight and limit velocity for a panel consisting of aluminium, glass fibre, foam and plies including Kevlar of 35 mm
  • point “g” are disclosed surface weight and limit velocity of 6 mm steel
  • point “h” is disclosed surface weight and limit velocity for 8 mm steel
  • point “i” is disclosed surface weight and limit velocity for 18 mm aluminium
  • point “j” is disclosed surface weight and limit velocity for 25 mm aluminium
  • point IIIA is disclosed surface weight and limit velocity for a panel of type Bv FMV 7 provided with a protective panel consist
