Abstract

STRUCTURE COMPOSITE COMPRENANT UNE AME. L'AME 12 EST FORMEE DE DEUX PHASES RIGIDES DONT L'UNE CONSISTE EN DE MULTIPLES SPHERES CREUSES ENROBEES DANS UNE SECONDE PHASE CONSISTANT EN UNE RESINE THERMODURCISSABLE, CETTE AME ETANT RECOUVERTE D'UNE MOUSSE 16 A CELLULES OUVERTES, INITIALEMENT ELASTIQUE ET IMPREGNEE DE RESINE THERMODURCISSABLE. UNE COUCHE D'ARMATURE 20 PEUT EVENTUELLEMENT ETRE LIEE A LA COUCHE DE MOUSSE 16. APPLICATION PAR EXEMPLE A LA REALISATION D'AILETTES LEGERES ET AYANT UNE GRANDE RESISTANCE MECANIQUE.COMPOSITE STRUCTURE INCLUDING A SOUL. THE CORE 12 IS FORMED OF TWO RIGID PHASES, ONE OF WHICH CONSISTS OF MULTIPLE HOLLOW SPHERES COATED IN A SECOND PHASE CONSISTING OF A THERMOSETABLE RESIN, THIS CORE BEING COVERED WITH A 16 OPEN-CELL FOAM, INITIALLY ELASTIC AND IMPREGENIC RESIN THERMOSETTING. A LAYER OF REINFORCEMENT 20 CAN POSSIBLY BE BONDED TO LAYER OF FOAM 16. APPLICATION FOR EXAMPLE TO THE REALIZATION OF LIGHT FINS AND HAVING HIGH MECHANICAL STRENGTH.
