| Current Projects at CeraNovaCeraNova is a member of the AFOSR-DARPA funded Active Fiber Composites Consortium (AFCC) program. The AFCC program is a three year effort working towards the development of Active Fiber Composites (AFCs) for use by program and commercial customers. CeraNova is the sole provider of the round, monofilament Lead Zirconate Titanate (PZT) fiber used in AFC packs. CeraNova's proprietary ceramics-based extrusion and firing methods produce consistently round, straight, and contamination-free PZT fibers with the piezoelectric performance needed for use in AFCs. AFC Packs use interdigitated electrodes to activate a monolayer of PZT fibers embedded in a polymer matrix. AFCs have greater actuation energy density, are more conformable, and more robust than monolithic piezoelectric materials. The AFCC is working towards rotorblade aeroservoelastic control through twist actuation of the blade by laminated AFC packs. Schematic diagrams of the pack and rotorblade designs are shown below.
Some of the other targeted testbed applications for AFC packs are illustrated below.
CeraNova is also a subcontractor to the AFOSR-DARPA funded Single Crystal Fiber (SCF) program for active fiber composites. The goal of this two year effort is to develop and demonstrate the feasibility of single crystal fiber materials for active fiber composites. The improved properties of single crystal fibers are expected to further enhance the performance of active fiber composite packs.
