ることを目的とする。An optical fiber has only a sensor function and cannot be used as an active actuator. Shape memory alloys can be used as actuators because they repeatedly change shape in both directions due to temperature changes. However, since the response is slow and there is a problem in the reproducibility of deformation, it cannot be used as a high-precision actuator. Piezoelectric ceramics have excellent responsiveness, but have the disadvantage that the displacement is extremely small.
Bimetals are two kinds of metals with different coefficients of thermal expansion bonded to each other. However, most of them are simply used as temperature sensors, thermometers, no-fuse breakers, etc., and have a function as an active actuator. Is hard to say.
As described above, a material that sufficiently exhibits the necessary actuator function as an intelligent material has not been put to practical use so far. The present invention has been devised to solve such a problem, and a composite material having an active actuator function is obtained by bonding materials having different coefficients of thermal expansion and using one of them as a heating element. The purpose is to obtain.

置する。DESCRIPTION OF THE PREFERRED EMBODIMENTS In a laminated composite according to the present invention, for example, as shown in FIG. 1, a prepreg sheet 10 of carbon fiber reinforced epoxy resin and an aluminum plate 20 are laminated via an insulating layer 30. The prepreg sheet 10 made of carbon fiber reinforced epoxy resin has a very low coefficient of thermal expansion, and can be said to be a material that does not substantially thermally expand as compared with the aluminum plate 20. For the insulating layer 30, it is preferable to use Kevlar fiber reinforced epoxy resin which is insulative and has a small coefficient of thermal expansion similarly to carbon fiber reinforced epoxy resin. The carbon fibers of the prepreg sheet 10 and the Kevlar fibers of the insulating layer 30 are oriented in the deformation direction of the aluminum plate 20 (corresponding to the longitudinal direction in the figure) because the coefficient of thermal expansion in the fiber direction is extremely small. Also,
The copper plates 40 are arranged on both ends of the prepreg sheet 10 so as to ensure conduction with the carbon fibers of the prepreg sheet 10.

複合体が得られることを意味する。When the prepreg sheet 10, the insulating layer 30, and the aluminum plate 20 are hot-pressed at the curing temperature of the epoxy resin (about 120 ° C.), the prepreg sheet 10 and the aluminum plate 20 are interposed via the insulating layer 30 as shown in FIG. A laminated composite in which the plates 20 are bonded is obtained. When a die having a flat press surface is used for hot pressing, the laminated composite immediately after hot pressing has a flat shape corresponding to the flat press surface. When the laminated composite is cooled to room temperature, the aluminum plate 20 undergoes a large thermal shrinkage as compared with the prepreg sheet 10, so that the aluminum plate 20 is bent with the aluminum plate 20 inside as shown in FIG. This deformation means that a laminated composite having a flat shape at room temperature can be obtained by forming a laminated composite having a curved shape by hot pressing.

自体としても十分な強度が確保される。The copper plate 40 provided at the end of the prepreg sheet 10 thus bonded is used as an electrode and connected to a heating power supply (not shown). When electricity is supplied to the carbon fibers of the prepreg sheet 10 via the copper plate 40, the prepreg sheet 10 functions as a planar heating element. As a result, the aluminum plate 20 thermally expands according to the temperature rise, and deforms the laminated composite with a displacement amount corresponding to the temperature. The displacement at this time is large compared to the conventional bimetal,
It can be controlled with high accuracy by the supply current. Further, since the shape reproducibility is good, it is used as a high-performance actuator. Moreover, since the structure is such that the carbon fiber reinforced resin is bonded to the metal plate such as the aluminum plate 20, sufficient strength is secured as the laminated composite itself.
