Abstract:

Task 1 High Volume Fraction 1-3 Composite. A semiautomatic ejection mechanism was designed and will be retrofitted into an existing MSI tool body. Semiautomatic ejection will minimize part distortion due to manual handling, decrease process time, and increase yields. Task 2 High Displacement Piezoceramic. More than fifty formulations of PLZT have been batched and tested to optimize the composition for the highest dielectric and piezoelectric properties with a target Curie temperature of 220- 230 deg C. Each formulation was sintered in both air and oxygen. Materials were tested for dielectric and piezoelectric properties 24 hours after polarization. Promising compositions were then tested for Curie temperature.
