Title (EN) PREFORM FOR MANUFACTURING A MATERIAL HAVING A PLURALITY OF VOIDS AND METHOD OF MAKING SAME
(FR) PREFORME POUR LA FABRICATION D'UN MATERIAU COMPORTANT UNE PLURALITE DE VIDES ET PROCEDE DE FABRICATION CORRESPONDANT
Abstract:
(EN) A beaded preform includes a plurality of adjacently positioned beads for forming a plurality of voids in an engineered material. The beaded preforms may be comprised of a filaments (single strand of beads) and mats (two-dimensional and three dimensional arrays of beads). The filaments and mats may be coated to become tows and laminates, respectively, which may then be assembled into composite materials. The preforms may be produced using novel manufacturing apparatuses and methods, and incorporated into known manufacturing processes to produce porous structures, including stress-steering structures, in any material including metals, plastics, ceramics, textiles, papers, and biological materials, for example.
(FR) L'invention porte sur une préforme comprenant une pluralité de billes positionnées les unes à côté des autres de façon à former une pluralité de vides dans une matière façonnée. Les préformes à billes peuvent être constituées de filaments Brin unique de billes) et de tapis (matrice de billes bidimensionnelles et tridimensionnelles). Les filaments et les tapis peuvent être gainés ou pourvus d'un revêtement de façon à former des câbles et des laminés qui peuvent être ensuite assemblés en matériaux composites. Le préformes peuvent être obtenues au moyen de nouveaux procédés et appareils de fabrication et sont incorporées à des processus de fabrication connus pour produire des structures poreuses telles que des structures d'organisation des contraintes dans n'importe quels matériaux tels que métaux, plastiques, céramiques, textiles, papiers et matériaux biologiques.
