IsoTruss®
grid structures 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.
Technical Description
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.
