Title (EN) SHOCK-ABSORBING PROTECTION ELEMENT FOR PACKAGING FOR THE TRANSPORT AND/OR TEMPORARY STORAGE OF RADIOACTIVE MATERIALS
(FR) ÉLÉMENT DE PROTECTION AMORTISSEUR POUR UN EMBALLAGE DE TRANSPORT ET/OU ENTREPOSAGE DE MATIÈRES RADIOACTIVES
Abstract: front page image
(EN)The invention relates to a block of a shock-absorbing protection element consisting of a rigid and fragile carbon foam, said block being provided with structural, superficial or internal irregularities (20), and having sharp-angled edges in the foam to enable the immediate crushing thereof by cracks which extend depth-wise throughout the entire volume thereof, stimulating the fragmentation thereof with foreseeable characteristics. As a variant, the following can be applied: a hardening surface coating (28) filling the outer pores (27) of the foam, lateral play with the envelope, or projections lining the inside of the envelope. The invention applies to shock-absorbing protection elements, which especially cover packagings that may be liable to fall.
(FR)Un bloc d'élément de protection amortisseur en mousse rigide et fragile de carbone est muni d'irrégularités de structure (20), superficielles ou internes, présentant des arêtes à angle vif dans la mousse pour permettre son écrasement immédiat par des fissurations se propageant en profondeur dans tout son volume, ce qui favorise sa fragmentation avec des caractéristiques prévisibles. En variante, on pourrait recourir à un revêtement durcissant (28) superficiel comblant les pores (27) extérieurs de la mousse, un jeu latéral avec l'enveloppe, ou des picots garnissant l'intérieur de l'enveloppe. Application aux éléments de protection amortisseurs anti-choc, notamment couvrant des emballages exposés à des chutes.
