Partridge and Amir Rezai, Mechanical property balance in novel Z-pinned sandwich panels: Determination of the out-of-plane properties, Composites Part A: Applied Science and Manufacturing, 37, pp295-302, 20061359-835Xhttp://dx.doi.org/10.1016/j.compositesa.2005.03.029http://dspace.lib.cranfield.ac.uk/handle/1826/842The 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 sen-UKArticle
