Fabrication and characterization of polymeric origami structure for compression properties
Bibliographic record
Abstract
Sandwich structures, which typically consist of two thin flat plates separated by a core, are commonly used in applications where the light weight considered as one of the influential design criteria. The core is usually designed in a certain way, allowing the structure to withstand the applied loads and to dissipate energy. The main function of the core in the sandwich structure is to redistribute the applied force by deformation and to dissipate the impact energy. The objective properties of sandwich cores are high stiffness to weight ratio, high bending stiffness, and high energy absorption ratio. The conventional designs of sandwich cores, such as foamed cores, honey-comb, and ribbed cores, have been used for many decades. Origami inspired sandwich cores have attracted attention during the last years, due to their high capacity for elastic deformation, force redistribution, bending and twisting resistance. In this paper, we present the results of a quasi-static compression test, and the energy absorbed by Muira origami folded cores, made by direct molding of polymeric blends. The material compositions used were polylactic acid (PLA) and thermoplastic polyurethane (TPU), and the weight percentage of these compositions were (100/0, 80/20, 65/35, 50/50, 20/80, and 0/100) (PLA/TPU). It has been found that cores with high PLA content have high stiffness values, while the cores with high TPU content have the high energy absorptions efficiency.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
