Properties & Advantages

IsoTruss® achieves its incredibly high strength-to-weight ratio with a special geometry that uses longitudinal and helically wound members.  The "iso" and "truss" in "IsoTruss"come from its efficient geometry; isosceles triangles that form a truss of pyramids which are what give the IsoTruss its unique strength and stiffness.

The IsoTruss® incorporates stable geometric forms with members that spiral in a piecewise linear fashion in opposing directions around a central cavity.  The helical and longitudinal members are repeatedly interwoven, yielding a highly redundant and stable configuration.


Cost Advantages

  • Initial cost vs. wood, steel, etc.
  • Maintenance - no rust , corrosion, rot; painting optional; no electrolysis
  • Cheap to transport, lift, handle, install
  • Repairable
  • Easy to replace
  • No hazardous/toxic chemicals
  • Recyclable material
  • Low energy costs, continuous, modular

Geometry
The IsoTruss® comes in many different geometric configurations.  This enables IsoTruss structures to be optimally tailored for a variety of applications.  Geometric variables include the number of nodes in a cross-section (e.g., 6, 8, etc.), diameters of the individual members, single versus double geometry, straight versus simple or complex curved segments, and uniform versus tapered overall diameter.  Naturally, any fiber and resin combination can be used to fabricate the IsoTruss lattice structure, although the web-like geometry lends itself to high performance fiber-reinforced polymer composites (e.g., carbon, fiberglass, aramid, or basalt fibers with an epoxy, vinyl ester, or polyester resins, etc.).
