Abstract:

This report contains a summary of research performed to explore the potential of a new, promising structural concept--continuous filament advanced composite isogrid. This is the first attempt to evaluate it in load bearing structure. A data base has been established by the design, fabrication and test of flat panels as wide columns. Correlation of the experimental results with theory, on a relative basis, is excellent. Inconsistency in manufacturing is clearly identified as the major reason for scatter in observed data, a problem which would not exist in a production environment. The results presented are a major step toward inspiring the necessary confidence in the use of this concept in airframe structure.
