Characterization of EA9396 Epoxy Resin for Composite Repair Applications
Abstract
A program was completed to develop material property data for an epoxy resin system for aircraft repair applications. The epoxy resin was developed by Hysol and is designated EA9396. An extensive array of mechanical property data was generated for both glass and graphite reinforced laminates. Comparative properties of three resin lots were obtained. The effect of several processing and environmental variables on laminate properties was determined and the effect of long-term storage was established. All laminates prepared and tested during this program were cured with vacuum bag pressure only. Mechanical tests were carried out at temperatures ranging from -65 deg F to 200 deg F on both dry and humidity-aged specimens. Processing variables that were studied included cure time and temperature, vacuum pressure level, resin impregnation procedure, alternate bagging schemes, alternate bleeder materials, and alternate resin/reinforcement ratios.
