Abstract
Structures, space frames, lattice materials and articles of a great variety of shapes including interconnected struts and methods to make and use same. The structures have no nodes and are made from struts including plates that are interconnected in a 3D woven pattern. The advantages are lower cost, improved performance, and simpler manufacture of parts and assembly relative to traditional frames and articles. In an embodiment, the method of assembling parts is a 3D weaving algorithm/methodology. The 3D woven structures can be used in a great variety of different ways.

- (iii) each of the polygons shares an edge with one or more adjacent polygons,
- (iv) each of the edges shares a vertex with one or more adjacent edges,
- (v) each of the polygons has a first face and an opposite face, wherein each face has an outward direction and the edges of each face are directed edges, wherein a direction of each directed edge is determined by a right- or left-hand thumb rule convention, and
- (vi) each of the faces comprises the wings, wherein each wing is associated with the directed edge of the face;
- (c) determining a shape and dimensions of the wings based upon the polygon mesh, wherein
- (i) a particular wing is associated with a particular edge of a particular face of a particular polygon in the polygon mesh,
- (ii) the particular wing is joined to a matching wing that is associated with the particular edge of the polygon mesh, wherein the matching wing is associated with a second face of a second polygon that has the particular edge, wherein
- (A) the outward direction of the particular face of the particular wing and the outward direction of the second face of the matching wing point into a same volume,
- (B) the directed edge associated with the particular wing and the matching wing point in opposite directions,

- (A) the directed edge associated with the particular wing and the second wing point in opposite directions,
- (B) the particular wing and the second wing are a wing pair,
- (C) when only the particular polygon has the particular edge, the second wing is the matching wing, and the wing pair is a matching pair, and
- (D) a winged strut comprises matching pairs and wing pairs associated with the particular edge;
- (iv) the particular wing shares a connecting tab surface with a third wing that is associated with an adjacent edge of the particular edge, wherein the third wing is associated with the opposite face of the particular face of the particular polygon that has the particular edge, wherein
- (A) the particular edge and the adjacent edge share a particular vertex of the particular polygon,
- (B) the directed edge associated with the particular wing and the third wing both point toward the particular vertex of the particular polygon,
- (C) the particular wing and the third wing are a connecting pair, and
- (D) a topological structure comprises a sequence of matching pairs and connecting pairs;
- (d) determining a shape and dimensions of the plates based on the polygon mesh, wherein each plate comprises one or more matching pairs, wherein when there are two or more matching pairs, the two or more matching pairs are joined at a shared connecting tab and/or strut tab surfaces.
- (e) fabricating the plates as determined by the step of determining the shape and dimensions of the wings;
- and
- (f) assembling the plates to form the structure, wherein the wings of the plates share strut tab surfaces and connecting tab surfaces.
