    • A method and system for fabricating a geometrically versatile composite lattice support structure having a seamless three-dimensional configuration. The lattice support structure is created by forming two or more cross supports, such as helical, longitudinal, circumferential and/or lateral cross supports, which intersect to form a plurality of multi-layered nodes. The lattice support structure may be designed without any protrusions extending outward from the overall geometry, thus enabling efficient tooling, and thus enabling ease of mass production. The lattice support structure may comprise a completely circumferentially closed geometry, such as a cylinder, ellipse, airfoil, etc. The method for fabricating the lattice support structure comprises laying up a fiber material, in the presence of resin, within rigid channels of a rigid mold, thus creating a green, uncured three-dimensional geometry of unconsolidated cross supports and multi-layered nodes where these intersect. Subjecting these to a curing system functions to consolidate the cross supports and multi-layered nodes to produce the composite lattice support structure.
    • 一种用于制造具有无缝三维构型的几何通用复合晶格支撑结构的方法和系统。 网格支撑结构是通过形成两个或更多个交叉支撑件(例如螺旋形,纵向的,周向的和/或横向的交叉支撑件)形成的,这些支撑件相交以形成多个多层节点。 网格支撑结构可以被设计成没有从整体几何形状向外延伸的任何突起,从而实现高效的模具,从而使得易于批量生产。 晶格支撑结构可以包括完全周向闭合的几何形状,例如圆柱体,椭圆形,翼型等。用于制造格子支撑结构的方法包括在树脂存在下将纤维材料铺设在刚性的刚性通道内 模具,从而形成一个绿色的,未固化的三维几何形状的未合并的交叉支撑和多层节点,其中这些相交。 将这些固化系统用于固化交叉支撑和多层节点以产生复合格子支撑结构。
