Characterization of Aerospace Grade Resins and Composites Through Pressurized Volumetric Dilatometry

Abstract

The technique of Pressurized Volumetric Dilatometry has been used to characterize the specific volume changes over pressure and temperature of several state-of-the-art aerospace thermoplastic and thermoset resins and composites and several pitch precursors for carbon-carbon composites. The materials studied were poly(etheretherketone) PEEK; HTA; HTX; PBO/PEEK; 3501-6 epoxy; AS4/3501-6 prepreg; IM7/8551-7A prepreg; IM7/5250-2 prepreg; Ashland Oil pitches A-240, A-60, A-70, and A-80; Reilly Coal Tar; and Mitsubishi's AR synthetic Mesophase Pitch. Accurate and reproducible Pressure-Volume-Temperature (PVT) data have been yielded by this technique. Important processing information such as Tg(P), CTE(TP), T-(P), Tc(P), cure shrinkage, and other phase changes which give rise to volume changes can be extracted from the PVT data.
