Abstract

Piezoelectric polyvinylidenefluoride films have been embedded between layers of composite laminates and cured at temperatures up to 200°C. The films retain much of their piezoelectric response upon cooling even though the cure temperature exceeds the melting point of the film. The response of these embedded sensors to impact loading is discussed. We have also used embedded sensors to monitor curing of reinforced low temperature curing epoxy films sandwiched between polycarbonate sheets and subjected to an intermittent external load perpendicular to the surface. The sensor response drops as cure continues since the stiffer resin transfers less load to the film.
