Characterization of Contamination Generation Characteristics of Satellite Materials
Abstract
The objective of this program was to develop a standard test method for measuring the kinetics of material outgassing and deposition of outgassing species. The program was divided into three phases. In Phase I the current state of outgassing and deposition measurement and modeling technology was reviewed and a test approach was selected for further development. The Phase I work is reported in AFWAL-TR-83-4126 Volumes I and II. In Phase II the selected method was developed and its measurement capability was critically evaluated. The Phase II work is reported in AFWAL-TR-85-4118. Following Phase II an apparatus capable of executing the test method was built under contractor funding. In the Phase II Extension the apparatus and test method were exercised and evaluated by generating a database for 20 typical spacecraft materials. This report reviews the work performed on Phases I and II, describes the test method and apparatus, and presents the data generated, under Phase II Extension. The materials tested included paints, film materials, adhesives, lubricants, and composites.
