US12339103 - Multilayer ballistic barrier and a method of making the multilayer ballistic barrier

A multilayer ballistic barrier comprising at least one barrier plate ( 1 ) having a thickness of up to 250 mm, made of an elastomeric material containing butadiene and a binder, and a fill ( 2 ) having a minimum thickness of 50 mm in the form of mineral aggregates of various fractions ranging from 0.5 to 80 mm. The application also relates to a method of making the multilayer ballistic barrier and its use for the construction of bullet-proof walls and floors intercepting projectiles with a kinetic energy up to 50 000 J.

This patent describes a multilayer ballistic barrier designed for use in bullet-proof walls and floors, featuring a barrier plate made of elastomeric material and a fill of mineral aggregates. The barrier can withstand projectiles with kinetic energy up to 50,000 J, and the patent also outlines a method for its construction.

Claim 1

A multilayer ballistic barrier comprising at least one barrier plate ( 1 ) and a fill ( 2 ), characterised in that the barrier plate ( 1 ) has a thickness of up to 250 mm and is made of an elastomeric material containing butadiene and a binder, while the fill ( 2 ) has a minimum thickness of 50 mm and is constituted by a mixture of mineral aggregates of various fractions ranging from 0.5 to 80 mm.
