Flexible Polyurethane Foams Filled with Coconut Coir Fibres and Recycled Tyre - Part II: Compression and Energy Absorption
Bibliographic record
Abstract
The mechanical properties of flexible PU foams filled with coconut coir fibres and recycled tyre were investigated. The densities of foam composites are slightly increase as 2.5 wt% filler loading to foams. Among all, the highest density value is 54.048 kg/m 3 as compared with pure foam which is 52.69kg/m3. In compression test, the compressive response of foam composites was presented in three different regions which are elastic, plateau, and densification. The compressive results show the foams filled with 2.5wt% (50F50P) offered the greatest properties. It shows an increment of 10.784% for compressive modulus whereas an increment of 9.329% for compressive strength as compared with pure PU foam. This result may attribute to its varying cellular structure. The compressive results also indicated that there was no any contribution from tyre particles to the foam’s compressive properties unless it is added as the composition described above. Nevertheless, the results of energy analysis show added fillers can enhanced the foam’s energy absorption characteristic. The energy absorbability is found increased on composite which having good compressive properties as well as having cellular structure of possess smaller cell size.

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.
