Abstract

fetched live from OpenAlex

The influence of maleated polypropylene (MAPP) on the mechanical/thermal properties of short latania fiber‐reinforced poly(propylene)/ethylene‐propylene‐diene‐monomer (SLF/PP/EPDM) composites was investigated. Two different MAPP weight percentages (0 and 2wt%) and five different fiber weight contents (0, 5, 10, 20, and 30wt%) were considered, where the density of MAPP at the fiber surfaces progressively decreased. For a given fiber loading, addition of 2wt% MAPP led to roughly a 3–9% increase in tensile/flexural moduli and strengths over SLF/PP/EPDM composites with no MAPP. Moreover, composites containing MAPP displayed a profound improvement (37–78%) in impact energy absorption. In addition, composite heat deflection temperatures notably increased by 3–4°C with MAPP addition. Microscopic imaging suggested that matrix crazing, fiber pull‐out, and fiber fractures were key failure mechanisms. Hence, SLF/PP/EPDM composites modified with 2%wt MAPP may serve as a low cost alternative to other natural fiber thermoplastic composites. POLYM.

Full frame distilled prediction

Teacher imitation

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.
