| Abstract: | The scheme of manufacturing hollow integrated core sandwich composites is investigated and experimental samples for meeting the requirements are made.The main mechanical properties in warp and weft direction of the hollow integrated core sandwich composites are obtained by edgewise tensile,edgewise compression,flatwise tensile,flatwise compression,double lap shear,and four point bending experiments.Some properties are compared with the honeycomb sandwich composites.Differences in mechanical property and damage modes between warp and weft direction of this material are studied.Some useful conclusions are obtained,thus establishing foundations for the structure design and property analysis of this material. |
