A comparison is made between ambient and accelerated aged panels and panels tested immediately after curing. Strength reductions as a function of time of aging and temperature for several orientations of laminates were determined. The effect of adding interlayers of glass scrim cloth between graphite plies was investigated. The high tensile strength graphite-epoxy material studied was Modmor® II graphite/Narmco® 5206 epoxy.
