The specific embodiment nine: the following present embodiment that specifies, the bobbin type heater 3 in the present embodiment step F is that other step is with the specific embodiment eight by computer-controlled resistor-type or radial pattern heater.
Marmem is embedded in an end of fiber weaving cloth, gets up with resin-coating equally and solidify together.What axially the articulating marmem adopted is that thickness is the marmem of 0.13mm.Axially the articulating marmem is of a size of 0.9m * 0.04m * 0.13mm, and the surface is the sinusoidal tooth of rule, and the size of a complete tooth is: tooth depth h=3.2mm, radius of curvature r=0.8mm, facewidth b=6.4mm.Shape state with cylinder is placed in the autoclave, and setting solidification temperature in early stage is 50 ℃, and heating rate is 2 ℃/min; Be 6～24 hours hardening time; Curing environment humidity is less than 30RH (relative humidity).After solidifying 24 hours early stage, place at ambient temperature, ambient humidity is less than 30RH, and temperature is 20 ℃, carries out later stage curing in not demoulding condition, and be 24～48 hours hardening time.It is more complete that such post processing gets material cured, promptly fully solidifies.The demoulding is carried out fining-off to complex, comprises the unhairing limit, finishing, polishing.After handling like this has been exactly the shape memory complex of a deployed configuration.The original shape of such shape memory complex is cylindrical.Heating makes it be deformed into tabular the connection, and the transition temperature of shape memory complex is 60 ℃～150 ℃.The moulding process of shape memory complex mainly comprises hand paste method, vacuum bag pressure method and wet method winding method.Resin is stuck with paste the even scrubbing brush of technology on fiber weaving cloth by hand, and make fiber cloth all wetting.Because the viscosity ratio of epoxy resin is bigger, so do not adopt mould in moulding process; Material is placed in the vacuum bag, vacuumizes (promptly adopting vacuum bag pressure method), vacuum pressure is controlled between 5MPa～20MPa.Vacuum bag is crimped onto on the cylinder type metal die, solidifies the planarization on the surface of back complex, cover whole moulds with the broadband adhesive plaster and fix for assurance.The complex that adds once more after the thermally coupled becomes tabular, on the bobbin heater that to be crimped onto heating-up temperature then and to be 100 ℃ of length be 1m.Bobbin type heater is by computer-controlled resistor-type or radial pattern heater.The effect of heater is to launch drive unit, is a kind of of resistance-type heater.After being crimped onto diameter and being on the 10cm bobbin type heater, the large scale structure just be curled into diameter less than 50cm, length is the little structure of the column type of 1m, the volume that occupies is less than 5% of deployed configuration.Preparation technology for the long fibre reinforced composite adopts winding process, and the axle of the wrapping machine that uses in winding process is chosen as diameter 7cm, and the diameter of winding material is 7.5～9.0cm.The two ends of the axial articulating marmem of the complex by twining preparation all are connected by cohering with composite.Composite after twining is placed in the autoclave solidifies.The later processing and the process that experimental results show that are consistent with step C and subsequent step thereof.
The shape memory polymer material that adopts in the above-mentioned embodiment all has two phase structure: promptly by the fixedly phase of shape memory with vary with temperature the reversible phase composition that can reversibly solidify and soften.Fixing being generally the mutually unformed area with cross-linked structure fixingly is called the thermoplasticity shape-memory polymer for the physical crosslinking structure mutually; Fixing have the chemical crosslinking structure mutually be called the thermoset shape memory polymer.Reversiblely vary with temperature curing that can be reversible and softening mutually, have the physical crosslinking structure.
The elementary heat of the shape-memory polymer that adopts in the above-mentioned embodiment-mechanically deform process is: at transfer of shapes temperature (T
r) more than, can apply external force and make its distortion; Keeping making it be cooled to T under the constant prerequisite of external constraint
rFollowing uniform temperature removes external constraint, the deformation energy of composing by being kept for a long time; When being heated to transition temperature once more when above, shape-memory polymer can automatically revert to the most original shape.Wherein transition temperature comprises glass transition temperature and melting transition temperature.
Adopting the main feature of shape-memory polymer in the above-mentioned embodiment is but that recovery strain is bigger, generally can reach more than 100%.But major defect is that mechanical properties such as the rigidity, intensity of material are relatively poor, and rigidity is lower in the shape memory Recovery Process, deformation-recovery power is less, kinetic stability and reliability are relatively poor.And composite material of shape memory can overcome above-mentioned defective preferably, and its rigidity, intensity in the shape memory Recovery Process are higher, and deformation-recovery power is bigger, and kinetic stability and reliability are higher, and the shape hold facility is better.
The application of shape memory complex in deployed configuration of above-mentioned embodiment made full use of the shape memory characteristic of shape-memory material, but the shortcoming of the shape memory characteristic of composite material of shape memory is the one-way of shape memory characteristic, realized that by the connection effect of axial articulating marmem in structure deployed configuration has the amphicheirality, really realized the reversible of expansion and curly course, and the driving energy that consumes is also much little than traditional structure by structural design.
Tube shaped memory complex with expended space described in the above-mentioned embodiment is verified its invertibity curling and deployed configuration, as shown in Figure 3, end in coiled structure passes through fixed pulley 4 fixed traction moving heavy objects 5, make shape memory complex vertical expansion, after heater began heating, the shape memory complex upwards launched under the effect of tractive force.
