Abstract
The manufacturing of nodal elements and/or ramifi cations with an optimised force fl ow is one of the major challenges in many areas of fi bre-reinforced composite technology. The examples include hubs of wind-power plants, branching points of framework constructions in building industry, aerospace, ramifi ed vein prostheses in medical technology or the connecting nodes of axel carriers. Addressing this problem requires the adaptation of innovative manufacturing techniques and the implementation of novel mechanically optimised fi bre-reinforced structures. Consequently, the potential of hierarchically structured plant ramifi cations as concept generators for innovative, biomimetic branched fi bre-reinforced composites was assessed by morphological and biomechanical analyses. Promising biological models were found in monocotyledons with anomalous secondary growth, i.e. Dracaena and Freycinetia, as well as in columnar cacti such as Oreocereus and Corryocactus. These plants possess ramifi cations with a pronounced fi bre matrix structure and a special hierarchical stem organization, which markedly differs from those of other woody plants by consisting of isolated fi bres and/or wood strands running in a partially lignifi ed parenchymatous matrix. The angles of the Y-and T-shaped ramifi cations in plants resemble those of the branched technical structures. Our investigations confi rm that the ramifi cations possess mechanical properties promising for technical applications, such as a benign fracture behaviour, a good oscillation damping caused by high energy dissipation and a high potential for lightweight construction. The results demonstrate the high potential for a successful technical tran sfer and led to the development of concepts for producing demonstrators in lab-bench and pilot plant scale that already incorporate 'solutions inspired by nature'.

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
