4.1 This test method consists of subjecting a sandwich construction to a uniaxial tensile force normal to the plane of the sandwich. The force is transmitted to the sandwich through thick loading blocks, which are bonded to the sandwich facings or directly to the core....
1 Flatwise Tension Test Setup C 297/C 297M – 04 sufficiently stiff to keep the bonded core or facings essentially ?at under load. Loading blocks 40 to 50 mm [1.5 to 2.0 in.] thick have been found to perform satisfactorily. Permissible tolerances for the loading blocks (along with ...
System Alignment—Excessive bending will cause premature failure. Excess bending should be eliminated from the test assembly. Bending may occur as a result of misaligned grips, poor specimen preparation, or poor alignment of the bonding blocks and loading fixture. ...
