The three-dimensional, yet relatively simple geometry of IsoTruss® grid structure provides substantial resistance to local and global column buckling, while lending itself to cost effective fabrication using batch or automated continuous manufacturing techniques. IsoTruss extrapolates the traditional 2-D triangle based truss to a 3-D truss made up of pyramids formed by isosceles triangles.
The IsoTruss® can support axial tension or compression, torsion, or flexure (bending) loads, or any combination thereof. Each individual member carries primarily axial loads, taking full advantage of the inherent strength and stiffness of continuous fiber-reinforced composites. IsoTruss structures are particularly effective when replacing structures that were stability-critical designs.
