Abstract: A technique for automated online inspection of manufacture of a fibre reinforced polymer composite part during automated ribbon placement (e.g. ATL or AFP) uses interferometric inspection (e.g. OCT) to detect deviations from a planned lay-up for the part, to identify defects. On line, real-time inspection (i.e. on-the-fly) is demonstrated, and edge type defects and whole surface defects are identifiable. A sensor is demonstrated that does not extend a working envelope of the robotic head used for rib bon placement.

Abstract: A method for laser induced breakdown spectroscopy (LIBS) calibration or LIBS assay comprises providing a plurality of reference samples, each having a respective, known concentration of an analyte, assaying each reference sample to obtain a respective LIBS spectrum, and for each reference LIBS spectrum, measuring an intensity of at least one spectral analyte line that varies with concentration of the analyte, and measuring a peak amplitude of at least one saturating line of a reference element. The ratio and known concentrations define a calibration curve for the analyte.
