A Study of the Induction Heating of Organic Composites

Abstract

A study of the application of induction heating to graphite-based composites, both thermoset and thermoplastic. Panels of IM-6/3501-6 and IM-6/ PEEK were processed in magnetic fields of 450-kHz and 25-kHz frequencies. A 15. 24-cm-diameter pancake-type induction coil was used with 10.2-cm x 10.2-cm, 16- ply specimens. Vacuum bagging provided the only consolidation pressure. Data include resin, fiber, void contents, 3-pt. and 4-pt. loading for mechanical properties evaluation, and thermal analysis (DSC and TMA). Comparisons are made to similar samples processed under a standard autoclave cycle. Additional variables studied and discussed include the use of various caul plate materials as field susceptors, effects of coil vibration, various prepreg lay-up orientations, and other sample thicknesses. A brief discussion of the overall field effects and value of induction heating for field repair is included.
