Pineapple (Ananas comosus) crop generates a high volume of harvest residues, resulting in significant environmental impact, primarily due to the large quantity biomass left after fruit harvesting. This study aimed evaluate fiber production and quality using two defibration methods, manual mechanical, on leaves from three strata MD2 pineapple plants subjected different pre-conditioning techniques: soaking water for 8 15 days, NaOH solution 1 hour. Results this demonstrated that 70 % were suitable defibration. The highest yields obtained middle upper plants, with values 8.98 12.4 g, respectively. extraction time was shorter mechanical method, being 22 times more efficient than method. method favored when no prior conditioning performed, extracting an average 50.5 g per plant. performed better or NaOH, between 14.5 16.3 Additionally, changes properties found depend stratum leaf techniques. Our results contribute explore potential uses extracted by highlight possibilities implementing

Pineapple leaf fibres represent a biodegradable raw material sourced from renewable resources whose use contributes to reducing the carbon footprint and limiting amount of waste generated. Their potential applications can effectively decrease industry's dependence on plastics support sustainable development, which should accompany production modern materials. In this study, polyurethane-based composites reinforced with various types natural cellulose fillers were developed investigated. Microcrystalline unmodified chemically modified pineapple used as reinforcements. The mechanical thermal properties produced materials determined compared. results tests indicated that both microcrystalline contributed reduction in polyurethane. A varying impact Young's modulus biocomposites was observed. presence modifiers influenced an increase melting temperature composite compared pure Integration into represents step toward more future, combining economic benefits environmental care. characteristics enhanced by fibres, their counterparts. This improvement comes unique structural fibres. When polyurethane (PU) is matrix material, it fills interfibrillar voids, creating cohesive bond between components.

Natural fiber-reinforced composites have become an important field of research due to their environment-friendly nature, low cost, lightweight, and excellent mechanical properties. In the current study, natural were fabricated by hand layup technique investigate influence pineapple leaf fiber (PALF) orientation on properties water absorption behaviors epoxy composites. Pineapple fibers, known for reinforcement capabilities, incorporated into polymer matrices at various orientations (45°, 60°, 75°, 90°) evaluate impact composite’s performance. Mechanical (tensile strength, flexural energy, micro-hardness) assessed understand how alignment influences overall structural integrity composite. Additionally, characteristics immersing specimens in measuring uptake over time. Results revealed that plays a crucial role enhancing strength tribological properties, with reinforced fibers aligned 90° demonstrating efficient load transfer reduced absorption. Conversely, oriented 45° showed relatively lower higher absorption, These findings suggest optimization can lead enhanced performance durability, making them suitable extensive range eco-friendly sustainable applications.

This investigation aimed to assess the impact of kenaf fiber on hardness properties natural composites derived from coir pith, with a focus their potential as sustainable components in automotive industry. The control group consisted 15 wt% pith powder, while experimental included powder along specified number layers mat. study sought understand implications for hybrid composite, especially relation increase layers. Sample size calculations, facilitated by Clincalc.com, utilized parameters 80% power, 0.05 significance level, and 95% confidence level. Each received 20 samples, resulting total sample 40. Noteworthy disparities were observed between groups. exhibited 42 shore D, whereas group, particularly 3 fiber-based showcased significantly higher 53 D. Statistical analysis p-value less than validated these findings. In practical context, suggested surface treatment an alkaline environment is put forth specific aim augmenting reinforced kenaf/epoxy composites. proposed improvement opens avenues enhanced utilization various applications within materials industry, where key factor, such durable structural wear-resistant surfaces.
