Temperature-independent, bullet-proof, laminated safety panel, e.g. for vehicles, comprises several supports and several energy-dissipating plastic layers with maximum dissipation at different temperatures

摘要

Penetration-resistant, bullet-proof and/or sound-insulating laminated safety panel comprises 1-10 or more supports and 2-10 or more energy-dissipating plastic layers of the same or different composition which produce their maximum energy-dissipating effect at different temperatures, so that the laminate shows the above properties over a range of at least 40 deg C. Laminated safety material with penetration-resistant, bullet-proof and/or sound-insulating properties as described in DIN 52290 Part 3 (06/1984), DIN EN 1063 (07/1993), DIN 52290 Part 2 (11/1988), DIN 52290 Part 5 (12/1987), DIN EN ISO 717-1 and 717-2 (01/1997) and/or DIN 52210 (08/1984). This laminate comprises 1-10 or more supports (1) of the same or different composition and 2-10 or more functional energy-consuming and energy-dissipating plastic layers (2) of the same or different composition, with each layer (2) and/or support (1) producing its maximum energy consuming/dissipating effect at a different temperature (or temperature range) so that the laminate shows the above properties over a wide temperature range of at least 40 deg C.
