FIGURES
1 Axes notation for sandwich cores
2 Sketch showing shear specimens attached to loading plates
and plane of action of applied loads
3 Compression test apparatus showing an adjustable
supporting base and slotted round bars in position on
the specimen ends. Deformations are being measured
with Marten's mirror compressometers
4 Test apparatus for tension flatwise test of core
material for sandwich-type constructions showing
specimens and fitting for applying load
5 Apparatus for conducting flexure test of sandwich
peel test
6 Type of apparatus suitable for making sandwich peel test
7 Possible modes of failure of sandwich composite under
edgewise loads: General buckling, shear crimping,
dimpling of facings, and wrinkling of facings either
away from or into the core
8 Apparatus for node strength tests
Describes the general requirements and procedures for testing sandwich core materials and for testing sandwich construction of the types used mainly in aircraft structures. Not inclusive of test procedures which apply only to a specified product, as these are included in detailed product specifications.
