Abstract
Abstract In this work, the possibility to produce polylactic acid ( PLA ) and agave fiber biocomposites by dry‐blending and rotational molding was studied. The samples were also produced by compression molding to compare the effect of processing conditions on the biocomposites properties. In particular, the effect of fiber content (0–40 wt.%) on morphology, density, porosity, thermal ( DSC ) and mechanical properties (tension, flexion, impact and hardness) was studied. Also, a complete analysis of the internal air temperature profiles was performed to determine the thermal behavior of PLA during the rotational molding cycle. The results showed that rotomolded biocomposites were successfully produced but had higher porosity than compression molded ones due to the absence of pressure while forming. This led to different level of mechanical properties reduction as fiber content increases. Nevertheless, for compression‐molded biocomposites, crystallinity (30% at 30 wt.%), tensile modulus (14% at 30 wt.%) and impact strength (71% at 40 wt.%) improvements were obtained compared to neat PLA .

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
