  • the temperature control can be chosen so that the tubes collapse partially, whereby the volume fraction of the packing material can be varied.

Abstract

Une plaque de blindage (1) comporte des cavités (2) dans lesquelles une pluralité de corps de remplissage (3) sont disposés de manière régulière ou irrégulière. Les corps de remplissage sont creux, de préférence en forme de billes ou de bâtonnets et se composent d'un matériau non métallique, de préférence du verre ou de la céramique. Les espaces entre les corps de remplissage sont remplis avec un matériau plastique, de préférence avec une mousse, par exemple de polyuréthane.
