Abstract
In this work, the effect of weld lines and density reduction on the morphology and mechanical properties of injection moulded fibreglass reinforced polypropylene structural foams is reported. In this first part, cell size, cell density, skin thickness as well as tensile and shear mechanical properties are reported. As expected, all mechanical properties decreased with density reduction. On the other hand, the presence of a weld line produced a more complex behaviour: lower tensile properties with higher torsion modulus. These results are shown to be related to a change in fibre orientation along the sample length which is the main factor controlling the mechanical response of these composite foams.

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
