Abstract
Abstract The chapter reviews and illustrates with examples the diverse applications of vibrational spectroscopy to the study of polymer composites, which are defined as materials consisting of a polymeric (thermoplastic or thermoset) matrix reinforced with fibers (carbon, glass, polymer) or inorganic particles. After some discussion of the experimental difficulties that must be dealt with in obtaining spectra of these heterogeneous materials, the literature is reviewed under the following subject categories: quality control of polymer composites; studies of reinforcements (carbon, glass, polymer fibers, inorganic particulate fillers, cellulose‐based fillers), their surface treatments, and interphases; thermoplastic matrices (crystallinity, orientation); thermoset matrices (the study and monitoring of curing by mid‐infrared, near‐infrared, and Raman spectroscopies); environmental degradation. The chapter concludes with a brief coverage of newer types of composite materials: nanocomposites based on layered silicates (nanoclays), sol–gel preparation methods, and carbon nanotubes; molecular composites; and polymer‐dispersed liquid crystals.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
