Le mat\u00e9riau composite HoverLIGHT est constitu\u00e9 d’un noyau en mousse d’aluminium avec des sph\u00e8res creuses encapsul\u00e9es. Leurs effets d’amortissement sont comparables \u00e0 ceux du magn\u00e9sium. Source\u202f: Fraunhofer IWU<\/figcaption><\/figure>\n<\/div>\n\n\n

Les instituts Fraunhofer IWU (machines-outils et technologie de formage) et IFAM (technologie de fabrication et la recherche sur les mat\u00e9riaux avanc\u00e9s) ont d\u00e9velopp\u00e9 un mat\u00e9riau composite qui associe la mousse d’aluminium avec des sph\u00e8res creuses remplies de particules. Baptis\u00e9e HoverLIGHT, cette solution, utilis\u00e9e pour la r\u00e9alisation
des structures de machines-outils, combine l\u00e9g\u00e8ret\u00e9, rigidit\u00e9 et amortissement des vibrations. Utilis\u00e9e dans un projet men\u00e9 avec le Groupe Chiron, ce mat\u00e9riau a amorti les vibrations d’un facteur 3 et a assur\u00e9 un gain de poids de 20\u202f% par rapport aux solutions habituelles. Ce qui conduit \u00e0 une plus grande pr\u00e9cision d’usinage et une dur\u00e9e de vie plus longue de la machine. Les bras robotis\u00e9s con\u00e7us comme des structures sandwich b\u00e9n\u00e9ficieraient \u00e9galement d’une rigidit\u00e9 \u00e9lev\u00e9e \u00e0 faible masse. Les chercheurs allemands poursuivent l\u2019am\u00e9lioration d\u2019HoverLIGHT et l\u2019\u00e9largissement de son champ d\u2019application. L\u2019objectif est d\u2019adapter les propri\u00e9t\u00e9s du mat\u00e9riau composite aux exigences d\u2019autres applications et de r\u00e9duire ses co\u00fbts de fabrication gr\u00e2ce \u00e0 des processus industrialis\u00e9s.<\/p>\n\n\n\n
