“…In particular, considering the heterogeneous shape of OPEFB fibers (i.e., non‐uniform length‐to‐diameter ratio), 35 which can be worsened in terms of variability when subjected to conditioning processes such as grinding and sieving, the reinforcement size was handled as a fiber length distribution rather than a single common mean value. Based on the results of a previous study, 7 the theoretical distribution that fitted the OPEFB fiber length data for each of the three fiber sizes used in the composite formulation was the three‐parameter gamma distribution.…”

“…Despite the relevance of this subject, less research has been done on it due to extremely time‐consuming demands from several methodologies to carry out this task, not to mention the physical constraints of specialized equipment to analyze fibers of this nature 6 . Thus, with the aim of keeping the methodology as simple as possible, a facile and replicable procedure was employed to overcome this issue based on previously developed work 7 . From which numerous length measurements of OPEFB fibers were obtained—far more than the number recommended for accurate characterization of fiber length distribution (at least 2000 measurements 8 )—along with a statistical analysis of the distribution followed by the fiber length data.…”

The performance of natural fiber‐reinforced polymer composites (NFRPCs) can be markedly affected by fiber length, to the extent that a sole mean value and standard deviation fail to accurately represent its overall dispersion. Hence, measuring the variability of fiber length is crucial to comprehend its influence on the properties of the resulting composites. Unfortunately, few studies have been conducted on this topic. This work consisted of two research stages: the first related to the effect of both fiber length distribution and processing temperature on the properties of oil palm empty fruit bunch (OPEFB) fiber‐reinforced vinyl acrylic composites, while the second stage analyzed the influence of the fiber length distribution on the material performance under accelerated weathering tests. Broadly, composites were characterized by tensile mechanical testing, optical microscopy and SEM, FTIR spectroscopy, TGA, and microbiological analysis. The key results showed that processing the material at temperatures surpassing 75°C did not lead to a homogenous phase between the components, rendering it unworthy of consideration. Furthermore, composites containing the longest OPEFB fibers exhibited the lowest elongation‐at‐break values. Regarding the incidence of aging treatments, pronounced effects were observed in those composites exposed to UV radiation and salt fog. In detail, the elongation at break decreased by up to 34%, while the tensile strength increased by up to 1 MPa, and Young's modulus rose by up to 17%. Finally, two fungal genera, Fusarium sp. and Rhizophydium sp., were identified on the OPEFB fibers; nevertheless, no fungal growth was observed on the composites.Highlights Natural reinforcement/filler size measured as fiber length distribution.

“…In the first stage, OPEFB wastes were dried at room temperature for 24 h and subsequently shredded using a SHINI blade mill, model SG-2348E (Ningbo, China). Thereafter, the fibers were dried at 103 °C for 3 h. In addition, the length of OPEFB fibers was measured using methodology proposed in a previous study [ 29 ]. In broad terms, fiber length data were obtained from 40 images through processing with ImageJ ® software.…”

Biological agents and their metabolic activity produce significant changes over the microstructure and properties of composites reinforced with natural fibers. In the present investigation, oil palm empty fruit bunch (OPEFB) fiber-reinforced acrylic thermoplastic composites were elaborated at three processing temperatures and subjected to water immersion, Prohesion cycle, and continuous salt-fog aging testing. After exposition, microbiological identification was accomplished in terms of fungal colonization. The characterization was complemented by weight loss, mechanical, infrared, and thermogravimetric analysis, as well as scanning electron microscopy. As a result of aging, fungal colonization was observed exclusively after continuous salt fog treatment, particularly by different species of Aspergillus spp. genus. Furthermore, salt spray promoted filamentous fungi growth producing hydrolyzing enzymes capable of degrading the cell walls of OPEFB fibers. In parallel, these fibers swelled due to humidity, which accelerated fungal growth, increased stress, and caused micro-cracks on the surface of composites. This produced the fragility of the composites, increasing Young’s modulus, and decreasing both elongation at break and toughness. The infrared spectra showed changes in the intensity and appearance of bands associated with functional groups. Thermogravimetric results confirmed fungal action as the main cause of the deterioration.
