The Influence of Borax Filler Addition on Damping and Vibration Response of S-glass/epoxy Composite Laminates
Bibliographic record
Abstract
This study aims to examine the influence of borax addition on damping and vibration response of S-glass/epoxy composite laminates. Natural frequency and damping response of particle filled composite laminates cantilever beam are determined with different mass ratios between borax and epoxy resin with hardener. Borax particles were used as replacement material with epoxy resin and their particle loadings (the ratio between mass of the borax over total mass of the epoxy with hardener+borax filler) of the samples were 0 (plain), 5, 10, 15 and 20 mass %, respectively. Vibration properties of samples were experimentally determined by using modal analysis procedures. For damping responses, half power band-width method was employed with first natural frequency value. The results indicated that the replacement of boron particles with epoxy resin by 5 mass % of particle loading" significantly increased the damping and natural frequency and further increase of borax content caused a reduction in damping and vibration values.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
