The demands to lower the cost and increase the reliability of solid rocket propulsion systems have forced the aerospace industry to investigate new materials and fabrication techniques. The performance specifications for stiffness, strength and temperature resistance make the process of finding better materials and processes quite challenging. Advanced structural plastics, such as liquid crystalline polymers, may meet these requirements. The Astronautics Laboratory (AL) has initiated an in-house program to determine if advanced polymers could beet the cost/performance/reliability requirements. Components identified for polymer application includes motor cases, ignitor housings and nozzles. Injection molded parts, fabricted from VECTRA(R), XYDAR(R), and RYTON(R) were designed and initial testing has started. In addition, compression molded CELAZOLE(R) was also evaluated. An overview of this program and the progress to date is presented.
