Abstract
An isogrid structure having inset strips of composite materials at the top and bottom of the grid webs. A preferably flanged isogrid basically consists of I-beam members arranged in an integral repeating pattern of substantially equilateral triangles. One flange may be integral with a skin sheet covering the structure. At least some of these flanges are provided with grooves running parallel to the beam webs, filled with advanced composite materials comprising high-strength fibers in a supporting matrix. Preferably, the fibers run parallel to the beam webs. Preferred arrangements of the fibers are described.
