Piezo Ceramic Fibers
Smart Material utilizes a textile spinning method to manufacture green PZT fibers. The manufacturing process is based on the ALCERU® method, which constitutes a modified Lyocell fiber manufacturing procedure. The patented manufacturing method allows for the production of green fibers and tubes of various diameters and length with a high PZT material loading factor.
PZT fibers typically do not reach the full bulk PZT material properties, due to the much smaller sintered volume properties. Normally, fibers with about 75% of the bulk ceramic characteristics yields satisfactory results for most applications.
Our current standard diameters for PZT fibers are 105µm, 250µm and 800µm. Available PZT-systems are Navy type II and Navy type VI. Smart Material utilizes PZT powders provided Ceramtec AG.
