Onze brevets d'invention sont décrits sur le thème de la fabrication des matériaux alvéolaires du futur. Un concept de conception assistée par ordinateur de structures métalliques moulées légères à structure alvéolaire a été développé. Sur la base de l'analyse des structures des substances inorganiques telles qu'elles sont présentées par les sciences naturelles, des structures alvéolaires de pièces métalliques moulées ont été proposées, s'inspirant de la structure des structures cristallines et amorphes, du diamant, de la structure des quasi-cristaux selon la mosaïque de Penrose et des nanotubes de carbone, ainsi que des procédés de fabrication de modèles en mousse pour ceux-ci dans l'atelier de fonderie. Les conceptions des pièces moulées et le mode de montage des grappes de modèles sur des collecteurs à plusieurs niveaux sont réalisés selon le principe du phénomène botanique de la phyllotaxie, sur la base de modèles issus de la géométrie fractale, par analogie avec les structures arborescentes et la structure de l'ADN. Des modèles de pièces moulées à ossature et alvéolaires sont présentés, qui remplissent de manière optimale l'espace dans le volume du moule en sable; leur fabrication tient compte de la théorie des surfaces minimales, à l'instar de la structure d'une mousse dont les alvéoles ont la forme de dodécaèdres pentagonaux.
