Abstract
In this study, an experimental investigation was performed to evaluate the potential of thermoplastic composites to be used for the fabrication of an automotive intrusion beam using the composite stamping process. To assess the potential of this technology, mechanical properties of several high performance thermoplastic composite materials were first evaluated on coupons. Due to their higher load and displacement at failure, the most promising materials for the fabrication of a composite intrusion beam were found to be glass fibre/polypropylene (GF/PP) and carbon fibre/polyamide 66 (CF/PA66) laminates. Then, stamped intrusion beams were manufactured from these composites using three different stacking sequences. The beams were later tested under three-point flexural loading. For all components, failure occurred at the attachment points. However, higher properties were obtained for ± 45 laminates for which shear-out failure could be avoided. From the load-displacement curves obtained, it can nevertheless be concluded that stamping of thermoplastic composites is promising for the fabrication of intrusion beams, but that further development will be required to avoid failure at the attachment points.

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
