Description of drawings
Fig. 1 is the organigram of the utility model embodiment shape memory alloy fabric.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The shape memory alloy fabric that present embodiment provides; can be used for technical fields such as biological medicine tissue repair, safeguard protection, electronic shield, intellectual material, camouflage and quick framework; realize the unlimited repeated use of alloy fabric, improve utilization rate, reduce cost.The surface of fabric is network structure, can whole form different shapes such as spherical, column, select the alloy silk/pipe with shape memory function or the certain thickness alloy flat filament of certain diameter, as Nitinol, cobalt-base alloys or ferrous alloy etc., use certain braid method, as formation such as rib stitch (among Fig. 1 shown in a), double rib weave (among Fig. 1 shown in the b), warp parallel interlacing method (among Fig. 1 shown in the c) or latitude flat sennit weaves (among Fig. 1 shown in the d), perhaps combination of different braid methods etc. is woven into alloy fabric.
According to the environment for use of shape memory alloy fabric, can select for use the above-mentioned cross section of mentioning to be circular circle silk, pipe alloy silk, perhaps cross section is that square, oval-shaped flat filament alloy silk forms fabric, material also can be according to the corresponding replacement of environment for use.Usually the alloy filament diameter of circle silk, pipe is 0.01mm-5.0mm; The thickness of flat filament alloy silk is 0.005mm-1mm, and width is 0.05mm-12mm, selects as required to get final product.
The shape memory alloy fabric that is formed by aforesaid way, can pass through heat treatment mode, set its original shape, and set its shape memory temperature scope, beyond this scope, alloy fabric can arbitrarily be set Any shape for, in case temperature reaches this shape and temperature range, alloy fabric can revert to original shape rapidly, and this process can repeat many times and not influence the shape retention properties of alloy fabric.
Be formation and the use that example is introduced shape memory alloy fabric with concrete experiment, adopting diameter is the Ultimum Ti silk of 0.02mm, in 5 ℃ environment temperature, adopt the braid method that warp and parallel intersect to be woven into the hardware cloth tube that diameter is 6cm, seal after working out and prevent the wire slippage.The alloy cloth that braiding is good is strapped on the stainless steel cylinder that diameter is 8cm, fixes shape with galvanized wire.The temperature of setting high-temperature heater is 450 ℃, treat temperature stabilization after, the stainless steel column that fixes alloy cloth is placed in the middle of the heating furnace, heating 15min takes out the cold water quenching, obtaining diameter is the hardware cloth tube of 8cm.The initial setting of this alloy cloth tube is shaped as the circle that diameter is 8cm, and the shape memory temperature scope is about 5 ℃, can stably preserve this cylindrical shape more than 5 ℃, may be formed into arbitrary shape below 5 ℃.
As can be seen from the above embodiments; the utility model embodiment shape memory alloy fabric is formed by the alloy silk establishment of shape memory function; pass through heat treatment mode; set its original shape; and set its shape memory temperature scope; beyond this scope; alloy fabric can arbitrarily be set Any shape for; in case temperature reaches this shape and temperature range; alloy fabric can revert to original shape rapidly; this process can repeat many times and not influence the shape retention properties of alloy fabric, can be used for the biological medicine tissue repair; safeguard protection; electronic shield; intellectual material; technical field such as camouflage and quick framework.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
