Study on ceramic/polymer composite fabricated by laser cutting
Piezoelectric ceramic/polymer composites are important smart materials that have found many sensor and mechatronic device applications. In this work, piezoelectric lead zirconate titanate (PZT) ceramic was cut using a high power laser to obtain very fine scale patterns. The advantage of using laser cutting is that new and innovative pattern design can be implemented. To illustrate this, fine concentric circular grooves were cut in a 10 mm diameter PZT disc and then the grooves were filled with epoxy to form a ceramic/polymer 2-2 composite, Also a 1-3 composite consisting of PZT rods imbedded in a polymer matrix was fabricated. The electromechanical propel-ties of these composites were measured and reported. (C) 2002 Published by Elsevier Science B.V.
