Regular Fiber Composite

Piezo Electric Regular Fiber Composite
Piezo Regular Fiber Composites


The 1-3 regular fiber composites was specifically developed for SONAR applications. 1-3 fiber Piezo composites are prepared by epoxy infiltration of fiber bundles and dicing of the cube-shaped blocks perpendicular to the direction of the fibers. This patented method is also called Arrange & Fill. Regular fiber distribution is achieved by using specific masks. Regular Fiber Composite are only available with 800µm rods and with fill factors between 25% to 48%.

Due to the production methods used, raw blocks of regular fiber Composite can be up to 10cm in length. These blocks can then be sliced into plates of a desired frequency or machined in to various specified shapes, including precise concave or convex contours.
