Influence of space environment on adhesives
Abstract
A study completed at LMSC concerning adhesives and processing and environmental effects on bi-material adherend bonding is presented. The study identified bonded-joint requirements for space vehicle hardware, adhesive and screened candidates, screened adherend surface pre-bond treatment, and bond strengths at elevated temperatures for selection of adhesive systems for long-term environmental exposures. The capability of selected adhesives to cure under various temperature-time schedules representative of design and manufacturing constraints is assessed, and selected adhesive/adherend bonded joints are evaluated after extended thermal-vacuum cycling exposure to simulated ten-year spacecraft orbital life space environments.
