Abstract
NIR diffuse reflectance spectroscopy is demonstrated to be a suitable on-line monitoring technique during the manufacture of carbon/phenolic resin prepreg cloth in terms of resin and volatile contents. Calibration models were generated using partial least square regression to relate the on-line spectral data to the components’ content. Due to its rapid and non-destructive nature, the NIR spectroscopic method is proposed as an alternative to traditional chemical analysis. 31 refs.
