Abstract

fetched live from OpenAlex

In this study, high‐density polyethylene/agave‐coir composites with two fiber contents (20 and 30 wt%) and different coir‐agave fiber ratios (1–0, 0.8–0.2, 0.6–0.4, 0.4–0.6, 0.2–0.8, and 0–1) were produced in a two‐step process using twin‐screw extrusion followed by injection molding. The effect of mixing two different natural fibers and the addition of coupling agent on water absorption, mechanical properties, and morphology is reported. The rule of hybrid mixture was used to predict the properties of the composites, showing a good agreement with the experimental data. The results obtained showed that the combination of different fibers produces composites with unique characteristics as coir fibers absorb less water than agave fibers, while at the same time increase more tensile and flexural strengths. On the other hand, agave fibers were found to improve the impact strength of coir composites. Also, the effect of water absorption on the mechanical properties was studied. Finally, the use of a coupling agent had a positive effect on mechanical properties, while lowering water uptake. POLYM. COMPOS., 37:3015–3024, 2016. © 2015 Society of Plastics Engineers

Not 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.
