6 Mechanical characterization on sub-component level
following, the investigated materials and configurations are introduced before the experimental studies are described.
Materials and configurations
The investigated configurations essentially comprise the previously introduced materials, while both, fully and partially potted inserts were investigated. Figure 71 illustrates
the investigated configurations and materials. The fully potted type is studied in three
configurations where only the core height varies (Figure 71 a). The partially potted type
is investigated in a single configuration (Figure 71 b). Typical inserts for application in
aircraft interior are studied. The Shurlok SL607-08-6S is a standard steel insert, which is
suitable for a wide variety of panel thicknesses. The ABS1005-08078T is a lightweight
plastic insert with bonded threaded steel bush. The nomenclature of the configurations
is adopted from the previous investigation levels.

6.1.1 Out-of-plane tension (pull-out)
Out-of-plane tension is also referred to as pull-out test. It is a common and well-studied
test setup for sandwich fasteners. Despite this, there is no standardized test method
