Abstract

fetched live from OpenAlex

The main objective of this experimental investigation is to study the absorption behaviour of fibre-glass reinforced epoxy matrix composite laminates immersed in distilled water, in ambient and 90'C temperatures, and its effect on the mechanical properties. A comparative study is carried out to evaluate the properties of dry and water immersed specimens, and to investigate damage caused by the aqueous environment and temperature. It is found that the degree of damage strongly depends on the immersion temperature. The fracture surfaces in three different environments are studied using a scanning electron microscope and micro-macro damage correlation is established. The threshold strain for the matrix crack initiation increases when the laminated are immersed in ambient water in comparison to that of a dry environment. Immersion at high water temperature leads to embrittlement of the glass fibres and matrix blistering resulting in a slight decrease in threshold crack initiation strain.

Full frame distilled prediction

Teacher imitation

Not 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.
