Abstract
Alumina has been widely used for personal armour plate due to its relatively low cost, acceptable hardness and fracture toughness. With the increasing threat level, a much improved ceramic material with better ballistic performance and lighter weight is required. This paper is presents a research work, where alumina reinforced with 2D and 3D alumina fiber mats has been successfully developed for evaluation. The 2D alumina fiber reinforced alumina composite consists of an alumina matrix reinforced with 18 vol% of alumina fiber mats. And the 3D fiber reinforced alumina composite is made with alumina matrix with a 2D alumina fiber mats along with multi-walled carbon nanotubes vertically grown onto the fiber mats. In this study, a detailed examination on fracture surfaces of both 2D and 3D reinforced composites is conducted with scanning electron microscopy to elucidate the contribution of multi-walled carbon nanotubes and alumina fibers in enhancing the fracture toughness of the alumina matrix. Transmission electron microscopy investigation is also conducted on the composite with the 3D reinforcement to provide information on the morphological features at the fiber/matrix regions.

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
