Investigation into the issue of out of specification flow data revealed that unregulated transportation conditions exposed 7781 prepreg with phenolic resin to temperature fluctuations up to 125°F. The temperature fluctuations have the potential to advance unwanted curing in the prepreg, making it unsuitable for manufacturing. However, this explanation does not account for the prepreg exceeding specifications above the upper limit. Another explanation was investigated that involved exposure to moisture. Moisture could be preventing curing from taking place and thus resulting in higher flow values. Data collection was unable to proceed past the preliminary stages due to the COVID-19 pandemic and thus no data-driven conclusions can be made. Further testing will need to be conducted to provide an understanding of how temperature and moisture affect 7781 prepreg with phenolic resin over time.
