Abstract
A disclosed process uses ceramic fiber fabrication technology and allows for novel composite designs, including composites with different polarizable material regions and composites with a gradient in volume fraction of polarizable material. Moreover, composites with fine-scale microstructures may be formed. The new forming method is an improvement to the traditional 'dice and fill' technique currently being utilized to form piezoelectric composites.
