Title (EN) HONEYCOMB STRUCTURAL BODY
(FR) CORPS STRUCTUREL EN NID D'ABEILLE (NIDA)
Abstract: front page image
(EN)A honeycomb structural body (10) having a plurality of flow-through holes (11) formed by dividing the structural body with partition walls and passing in axial direction, wherein slits (12) are formed so as to be exposed to at least a part of an outer peripheral surface (13) along the axial direction of the structural body, whereby, because the parts of the honeycomb structural body are allowed to be deformed freely independently of each other, a thermal stress can be reduced and cracking is prevented from occurring even if a temperature distribution is nonuniform.
(FR)L'invention concerne un corps structurel NIDA (10) comportant une pluralité de trous d'écoulement (11) formés par division du corps structurel au moyen de parois de séparation et passage dans la direction axiale. On constitue des fentes (12) destinées à être exposées au moins à une partie d'une surface périphérique externe (13) le long de la direction axiale du corps structurel. Puisque les parties du corps structurel NIDA peuvent se déformer librement indépendamment les unes des autres, on peut ainsi réduire la contrainte thermique et empêcher les fracturations même si la distribution de température n'est pas uniforme.
