Abstract
Tests were performed measuring the temperature, ionic conductivity, and compaction in 16 to 200 ply thick graphite-epoxy laminates made of either Fiberite T300/976 (tape or fabric) or Hercules AS/3501-6 (tape). The data were compared to results calculated by the Loos-Springer CURE model. Good agreement was found between the model results and the data indicating that the model can be used to select the cure cycle. It is also shown that the cure cycle recommended by the manufacturer may result in ex cessive temperatures and in incomplete compaction and cannot be used to manufacture "thick" or even moderately thick composites.
