摘要: The objectives of this study are to investigate the basic mechanical properties TEEK-L polyimide-foam a balloon type and filled aramid-honeycomb core-materials for sandwich structures compare their with those AIREX R82 ROHACELL WF foam core-materials. Compression, tension, plate-shear tests provided stress–strain relationships, elastic modulus, strength. test results compared discussed. major obtained are: (1) Filling aramid honeycomb cells can improve an core-material, in particular making them higher than values expected from principle superposition compression equal tests. (2) superior 110 equivalent 110, where three materials have densi...
