Abstract
The growth of industry has caused a rise in the need for materials that create friction.This has led to significant environmental problems at every stage of their existence.As a result, there is now a strong emphasis on creating brake friction materials that are environmentally friendly and sustainable.This study investigates the mechanical and tribological characteristics of Pineapple Leaf Fiber (PLF), a natural fiber, and vermiculite, an industrial waste, as environmentally acceptable additives to improve the behaviour of braking friction composites.Four samples were created, each having varying ratios of vermiculite and PLF.These samples were then evaluated using a friction testing equipment with adjustable speed.The results indicate that the utilization of the environmentally friendly alternative combination can significantly enhance the friction coefficient, minimize friction variations and thermal deterioration.However, it should be noted that the wear rate will also proportionally rise as a result.Furthermore, the deteriorated structure provides evidence of the creation of the contact platform and the process by which wear occurs.The study utilized a hybrid integration of CRITIC (criteria importance through inter-criteria correlation) and multi-objective optimization by ratio analysis (CODAS) to objectively weigh different assessment indicators and rank the samples.The sample containing 6% PLF (polytetrafluoroethylene) and 8% vermiculite demonstrated superior overall tribological performance.

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
