Abstract (en)

[origin: EP0897097A2] The sandwich protective plate material has thin metal plates, using a very hard metal with high expansion. The leading hard foam layer (3), towards the effects of a blast, has a bulk density of at least 100 kg/m<3>. A dynamic and pressure-resistant plate (11) is of plastics. The structured components (6) are of a relatively light and stiff material, resistant to bending, with a high plastic take-up, using a metal and/or a plastics and especially an elastomer with carbon or glass fibre reinforcement. The thin limit layers (7,8) are of multi-angle or otherwise shaped and/or corrugated intermediate layers (9) or intermediate bodies which are bonded to give open passage channels (12) or spaces between the limit layers (7,8), or flat part-spaces.
