摘要

This paper describes the modeling, fabrication and characterization of a Carbon Fiber Reinforced Polymer plate with embedded fiber optic strain sensors and surface mounted piezoelectric actuators. The purpose of this study was to design a test article which could actively correct the induced thermal distortions of a composite using surface mounted piezoelectric actuators. The composite plate was modeled using finite element analysis to determine the optimum lay-up and actuator positions for the final composite design. A 30.5 cm composite plate was then constructed with embedded fiber optic sensors, and piezoelectric actuators were surface-mounted to the plate. Finally,k the shape of the plate was characterized by measuring the distortion produced by the piezoelectric actuators.
