Ballistic block for a bullet resistant glazing
The invention relates to a ballistic block ( 10 ) particularly for a bullet-resistant glazing ( 100 ) or as bullet-resistant glazing ( 100 ), wherein the ballistic block ( 10 ) comprises at least two transparent panes ( 11, 12, 13, 14 ) joined to one another via an interlayer ( 19 ), whereby the ballistic block ( 10 ) is constructed without an energy-absorbing layer or polycarbonate film, and whereby the at least two transparent panes ( 11, 12, 13, 14 ) and in particular all the transparent panes ( 11, 12, 13, 14 ) of the ballistic block ( 10 ) are each panes made of toughened glass.
1 . A ballistic block for a bullet-resistant glazing, wherein the ballistic block comprises
at least two transparent panes joined to one another by an interlayer, wherein the interlayer is composed of at least partly or partially from an ionoplast polymer,
a first side defined by one of the at least two transparent panes,
a second side opposite the first side,
wherein the second side is defined by another one of the at least two transparent panes,
wherein the ballistic block does not include a further energy-absorbing layer on the first side,
wherein ballistic block does not include any polycarbonate, and
wherein the at least two transparent panes are each made of heat-strengthened glass having a flexural strength of 70 N/mm 2 to 120 N/mm 2 ,
wherein the ballistic block does not include a hollow space between any of the at least two transparent panes from the first side to the second side, and
wherein the at least two transparent panes are combined by the interlayer into one structurally self-supporting unit such that when the ballistic block is installed, the ballistic block is retained on no more than two sides of the ballistic block.
2 . The ballistic block according to claim 1 , wherein the interlayer is an SGP film, and wherein the interlayer has an overall maximum nominal thickness of 0.9 mm.
3 . The ballistic block according to claim 1 , wherein the ballistic block has a symmetrical and monolithic construction.
4 . The ballistic block according to claim 1 , wherein the ballistic block includes a thickness measured from the first side to the second side, and wherein the thickness is configured to resist the ballistic fire from a 7.62×51 mm full metal jacket/hard core round pursuant to the standards under DIN 1063.
5 . The ballistic block according to claim 1 , wherein the ballistic block is curved.
6 . The ballistic block according to claim 1 , wherein each of the first side and the second side of the ballistic block is configured to act as an outermost attack side of the bullet-resistant glazing and resist ballistic fire pursuant to the standards under DIN 1063.
