Abstract:

This report, Volume III in a set of three volumes, contains results of Mode I static testing of composite sandwich structures for sandwich variables not tested in Volume I. The first volume contains results of Mode I static testing, and the second volume contains results of Mode I fatigue testing. This report contains the supplemental static test results of an investigation carried out to further understand the influence of sandwich parameters‒such as core type, cell size, core density, disbond location, fabrication process, ribbon direction, and crack-tip location‒on the onset and growth of damage in sandwich composites. Core properties such as core density, cell size, and core type influenced fracture toughness. Fabrication processes had no effect on fracture toughness. The information gathered throughout this research will be instrumental in developing analytical methods and validating finite element analysis procedures to further investigate the damage growth mechanics of sandwich composite structures. The data can also be used in the design of sandwich structures constructed from similar materials and geometries tested here.
