Delta7 manufactures unique and ultra-light carbon fiber frame bikes using IsoTruss® grid structures to offer a lightweight and efficient alternative to traditional wood, steel, aluminum and composite structures. The highly symmetric and redundant nature of IsoTruss structures provides an attractive, efficient, and damage tolerant design. The open grid enables a variety of standard and innovative connections. This unique form of advanced composite grid structure is revolutionizing structures as they exist today, resulting in lighter, more architecturally appealing, and more environmentally friendly structures.
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.
