Abstract
A metal hollow sphere (MHS) sheet structure is developed and its mechanical property is investigated. We performed piercings for steel MHS and placed them on a piece of tungsten wire to make an MHS thread. MHS sheets with two kinds of construction have been developed using the thread; plain weave construction and reverse stitching construction. Their tensile property is investigated through tensile test, where advanced specific tensile strength and plateau tensile behaviour are found. Its mechanism is investigated using video and the properties compared with conventional MHS clusters. A block cluster is made from the sheet and compression property is researched by observing their breaking behaviour. The sheet is introduced into a pure aluminium tube and energy absorption through side compression is evaluated.
