CURVED SHAPE ACTUATOR DEVICE COMPOSED OF ELECTRO ACTIVE LAYER AND FIBER COMPOSITE LAYERS |
摘要 |
The piezo-composite curved actuator of the present invention comprises a piezoelectric layer (10), a lightweight fiber-reinforced lower composite layer (20) with a high CTE (coefficient of thermal expansion) and a low modulus, which is placed under the piezoelectric layer, a lightweight fiber-reinforced upper composite layer (30) with a low CTE and a high modulus, which is placed on the piezoelectric layer, and an insulator layer (23) placed between the piezoelectric layer and the upper composite layer. The piezo-composite curved actuator may further comprise an insulator layer (24) placed on the upper composite layer. Also, the piezo-composite curved actuator may further comprise insulator layers (22) placed between the insulator layer (23) and the lower composite layer (20) at the both sides of the piezoelectric layer (10). |
