Abstract
Porosity is a critical defect in composite materials used in aerospace structures, influencing mechanical strength, fatigue performance, and overall component reliability. Standard aerospace practice demands porosity levels below 2% [1, 2]. Despite the availability of destructive and non-destructive testing methods, there exists no industry-wide standardized procedure for porosity quantification. This article presents a comprehensive and multi-phase research effort led by TecScan, in collaboration with academic partners and researchers, to develop a reliable and non-destructive ultrasonic testing method for quantifying porosity in carbon-fiber reinforced polymer (CFRP) composites using ultrasonic attenuation. The focus of this work is to meet the stringent NDT and quality control demands of aerospace-grade materials.

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
