To fully characterize a composite material requires an extensive series of experimental tests. The number of tests required though may vary depending on the material behavior and the application. This section briefly describes experiments that have been used to obtain composite material properties for studies using the material models described in 3 and 4. The testing strategy described in this chapter has been developed under ESA research contract No. 12400/97/NL/PA(SC) and performed by Ernst Mach Institute (EMI), Freiburg, in conjunction with Century Dynamics, [1][2].
