Delamination Resistance of Fibre Reinforced Polymer (FRP) Plate Subjected to Out-of-Plane Loading
Bibliographic record
Abstract
Delamination resistance of fibre-reinforced polymer (FRP) was characterized directly from plates that were subjected to out-of-plane loading. Plate specimens used in the study were designed to be mainly unidirectional (0°), with a single layer containing fibre in the orthogonal direction (90°) inserted at the mid-thickness. The test set-up followed the description given in ASTM D3763-02, but using indenter of large radius to minimize the indentation damage. The study found that the out-of-plane loading on the top surface generated firstly a flexural splitting crack in the 0° direction from the bottom half of the plate. The splitting crack facilitated the delamination growth, resulting in a peanut-shaped area in the interlaminar region underneath the 90° layer. The delamination resistance was characterized using the rate of energy loss per unit area of delamination growth, of which the value was found to be consistent with that determined previously, using flexural tests on beam-type specimens.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
