Abstract:

The first actuator module delaminated during burnout. The module showed evidence bulging of pressure build up internally which is usually caused by too rapid burnout schedule. The next module is being fabricated and will be in burnout by the end of this week. The pad of smaller actuators look good and are terminated ready for testing. Plans for September 1993 Electromechanical measurements will be on the first set of small actuator, Electromechanical modelling on the actuators will be conducted. Two actuator module iterations will be conducted. One will use a burnout profile based on a conventional 100-mg sample size thermogravimetric analysis result the other will be in a specially rigged furnace to monitor temperature, weight loss and strain during the burnout-- this sample will essentially be sacrificed but the amount of information gained will enable us to optimize the burnout cycle for this actuator size
