ABSTRACT:
The present invention relates to a safety composite system, and/or intermediate layer films suitable for therein, having a high penetration resistance, i.e., energy absorption on sudden mechanical stress and to a process for the determination of the maximum energy absorption of intermediate layer films on sudden mechanical stress. The thickness-dependent energy absorption E [J/mm] of at least one film is determined according to DIN EN ISO 8256 on a test specimen of the safety composite system provided with pre-broken transparent panels and amounts to at least E>d−b, d being the film thickness and b being a constant. The safety composite system can be used in particular for the manufacture of composite glazings.
