Single-Lap-Joint Screening of Hysol EA 9309NA Epoxy Adhesive

Abstract

A commercial 2-part epoxy was evaluated per ARL-ADHES-QA-001.00 rev 1.0, which consists of single-lap-joint testing at room temperature and subsequent hot/wet and elevated temperature conditioning. This testing protocol is intended to provide a minimal recommendation for adhesive selection for Army ground vehicle applications. The epoxy adhesive used for this research is a known aerospace benchmark and was selected to judge the stringency of ARL-ADHES-QA-001.00 rev 1.0, which suggests that the elevated temperature strength retention requirements should be relaxed.
