NASA TECH BRIEF. Isogrid is a type of partially hollowed-out structure formed usually from a single metal plate (or face sheet) with triangular integral stiffening ribs (often called stringers). It is extremely light and stiff. Compared to other materials, it is expensive to manufacture,, A quasi-isotropic composite structure includes a multi-sheet rib projecting generally perpendicular to a multi-sheet body with at least one of the body face sheets being bent and attached in a parallel manner to the rib sheet or sheets. The sheet or sheets that are part of both the body and rib are unsevered and integrally contiguous..

This book reveals the design and development history of the naval Phantom, its variants and the exported designs adopted by other NATO countries. Isogrid structure is one of the best choice for achieving the payload gain in aerospace field. The ribs that constitute the isogrid are arranged in three categories so that a repetitive lattice of triangular cell structure is formed. This rib pattern forms triangular trusses by maintaining isotropic property.
