Abstract:
The paper presents the first complete set of test results obtained from quasi-
static measurements of the out-of-plane tension, shear and compression
properties of novel XCor ™ and K-Cor™ flat sandwich panels. The cured panels
were composed of 0.75mm thick quasi-isotropic IM7/8552 skins, separated by 12.7
mm thick Rohacell® foam core containing 0.51 mm diameter carbon fibre pins (Z-
Fiber®), arranged in a truss pattern at pin angle of either 22° or 30° to the
vertical. To obtain a suitable baseline comparison, the equivalent set of
properties was measured for Nomex honeycomb core panels sandwiched by the same
composite skins. The novel Z-pinned cores are found to exhibit higher specific
stiffness than conventional sandwich cores, but lower s
