Abstract: A flexible layer support structure and a retractable device is disclosed. The flexible layer support structure includes a first thin sheet and a second thin sheet arranged in parallel with each other, as well as and a folding spring group sandwiched between the first thin sheet and the second thin sheet and arranged in parallel. The curved elastic pieces in the folding spring group are smoothly overlapped and connected with the thin sheets, so as to enclose a hollow thin-walled elastic structure that can be overlapped and rolled up, can be automatically straightened and has a flat surface. The retractable device includes a winding shaft, a pressure roller, and a flexible layer support structure installed on the winding shaft. The flexible layer support structure of the present disclosure has the advantages in lightweight, high storage ratio, large unfolded area, simple winding, large load bearing capacity, and less damage.

Abstract: A frustum embedded fabricated composite protective structure is provided, including a restraint frame, a back plate, an infill block and a buffer block. The restraint frame is provided with a plurality of mounting holes matching with the shape of the infill block, the restraint frame is arranged on the back plate, the infill block is in a frustum shape. The buffer block and the infill block are installed in the mounting hole of the restraint frame, the buffer block is arranged on the smaller end of the infill block, and the infill block is wedged into the mounting hole of the restraint frame through a wedge surface mating. Because this protective structure is assembled by multiple restraint frames and infill blocks, under the prestress restraint of partition blocks, the damage range after penetration or explosion will be significantly reduced, and it can withstand multiple blows.

Abstract: The present invention relates to a corrosion-induced shape memory fiber, a preparation method and application thereof. The corrosion-induced shape memory fiber is composed of a core fiber and/or a core fiber with a corrosion-resistant coating, and a corrodible coating; the core fiber and/or the core fiber with the corrosion-resistant coating are in a tensile stress state along the length of the corrosion-induced shape memory fiber; the corrodible coating is in a compressive stress state along the length of the corrosion-induced shape memory fiber; the core fiber and/or the core fiber with the corrosion-resistant coating and the corrodible coating are in a tensile-compressive equilibrium state along the length of the corrosion-induced shape memory fiber; and the corrodible coating is coated outside the core fiber and/or the core fiber with the corrosion-resistant coating.

Abstract: The present disclosure relates to an oxidation-induced shape memory fiber comprising a tension-bearing core material and/or a tension-bearing core material coated with an antioxidative coating, and an oxidizable pressure-bearing coating. The oxidizable pressure-bearing coating is coated outside the tension-bearing core material and/or the tension-bearing core material coated with an antioxidative coating; the oxidizable pressure-bearing coating is in compressive stress state and/or the tension-bearing core material coated with an antioxidative coating and the oxidizable pressure-bearing coating are in tension-compression balance state. The disclosure also relates to preparation and application thereof, the preparation is: reserving anchoring end, exerting tension force on tension-bearing core material and/or tension-bearing core material coated with an antioxidative coating, followed by coating oxidizable pressure-bearing coating thereon. The oxidation-induced shape memory fiber is applicable to high temperature oxidation environment.
