摘要： The invention relates to a composite honeycomb (1) comprising a plurality of contiguous cells (2) each of substantially hexagonal cross-section, each cell (2) comprising a lower part (50) and an upper part (60), said lower part (50) comprising three lower cell walls, namely a lower horizontal cell wall (51) and two lower inclined cell walls (52), and said upper part (60) comprising three upper cell walls, namely an upper horizontal cell wall (61) and two upper inclined cell walls (62), characterized in that each of said cell walls (51,52,61,62) are substantially of the same thickness, in that each lower part (50) comprises fiber-reinforced material including a plurality of structural fibers (40) arranged to provide a continuity of fiber-reinforced material between said lower horizontal cell wall (51) and said two lower inclined cell walls (52) of said lower part (50) and in that each upper part (60) comprises fiber-reinforced material including a plurality of structural fibers (40) arranged to provide a continuity of fiber-reinforced material between said upper horizontal cell wall (61) and said two upper inclined cell walls (62) of said upper part (60), so that stress and strain applied to said composite honeycomb (1) can be transmitted from said horizontal cell walls (51,61) to respective inclined cell walls (52,62).
摘要翻译：本发明涉及一种复合蜂窝体（1），其包括大致六边形横截面的多个连续孔（2），每个孔（2）包括下部（50）和上部（60），所述下部（50）包括三个下部细胞壁，即下部水平细胞壁（51）和两个下部倾斜细胞壁（52），所述上部部分（60）包括三个上部细胞壁，即上部水平细胞壁（61）和两个上倾斜单元壁（62），其特征在于，每个所述单元壁（51,52,61,62）基本上具有相同的厚度，因为每个下部（50）包括纤维增强材料，包括多个的结构纤维（40），其布置成在所述下部水平细胞壁（51）和所述下部（50）的所述两个下部倾斜细胞壁（52）之间提供纤维增强材料的连续性，并且每个上部（60））包括包括多个结构纤维（40）的纤维增强材料在所述上部水平细胞壁（61）和所述上部（60）的所述两个上部倾斜细胞壁（62）之间提供纤维增强材料的连续性，使得施加到所述复合蜂窝（1）上的应力和应变可以从所述水平单元壁（51,61）传送到相应的倾斜单元壁（52,62）。

摘要： The invention relates to a method of producing a composite honeycomb (1) formed of a plurality of honeycomb cells (2) each of substantially hexagonal cross-section and with each wall of said honeycomb cells (2) of substantially the same thickness, comprising the following steps:
a) producing at least four corrugated sheets (3,4,5,6,20,21), namely a first (3), a second (4), a third (5) and a fourth (6) corrugated sheet, by interconnecting a plurality of substantially U-shaped elements (9) with substantially inverted U-shaped elements (9'),
wherein said U-shaped elements (9), respectively said inverted U-shaped elements (9'), comprise each fiber-reinforced material comprising a plurality of structural fibers (40),
wherein said U-shaped elements (9) and said inverted U-shaped elements (9') comprise each a horizontal side (7) and two inclined sides (8),
and wherein each inclined side (8) of each U-shaped element (9) is brought into contact and bonded with one inclined side (8) of one of said inverted U-shaped elements (9'),

b) stacking said first (3), second (4), third (5) and fourth (6) corrugated sheets upon each other so as to form a corrugated sheets stack (30) and so as to obtain a plurality of substantially hexagonal honeycomb cells (2) by bringing into contact horizontal sides (7) of adjacent corrugated sheets (3,4,5,6),
c) stacking subsequent corrugated sheets (20,21) upon said corrugated sheets stack (30) according to the step b) until obtaining a desired width (w) of the composite honeycomb (1),
d) and bonding horizontal sides (7) of corrugated sheets (3,4,5,6,20,21) brought into contact either concomitantly as a whole or sequentially in pairs as one of said corrugated sheets (3,4,5,6,20,21) is stacked upon an other one.
