A key contemporary challenge is enhancing the value of agro‐industrial byproducts. Cellulose, the most abundant renewable resource, offers significant industrial potential due to its versatile properties. Produced in its pure form by various bacteria, cellulose is increasingly utilized in microscale and nanoscale fibers for composite reinforcement. In this study, cellulose microfibers were derived from palm sprout fibers through a series of treatments like pretreatment, high‐pressure hydrolysis in an autoclave, and bleaching. These fibers were then characterized using techniques such as UV spectroscopy, FTIR, SEM, and XRD. The study evaluated the antibacterial properties of the treated cellulose microfibers against both gram‐positive Staphylococcus aureus (07%) and gram‐negative Escherichia coli (10%), finding higher effectiveness against E.coli. Additionally, the microfibers exhibited a lower EC50 value of 0.101 mg/mL, suggesting that although the microfiber extract is effective, the standard antioxidant is somewhat more potent. Adsorption studies revealed that the cellulose microfibers followed the Langmuir isotherm model, with a high determination coefficient of 0.998, and reached maximum dye adsorption for RB 160 within 120 min. In this adsorption study, 50 mg of dye was removed. These results indicate that the treated cellulose microfibers are a promising biosorbent for improving dye removal processes.

The present work highlights the benefits of matrix strengthening through the inclusion of hard particles within the resin‐impregnated woven Kevlar mat. Aluminium Oxynitride (ALON) particles are added to epoxy resin by 5, 10, and 15 volume percentages. The test coupons were developed through a hand‐lay‐up technique to estimate the low‐velocity impact resistance. The characterization was performed through EDAX and SEM to ensure the presence of the ALON particles and their homogenous distribution respectively. Low‐velocity testing is preferred to assess the capacity of the materials to rebound the incident energy. The damage assessment was made to estimate the material's stiffness. The compression after impact (CAI) was executed to observe the strength of the material after the impact. The post‐CAI micrographic observation reveals the delamination history. The results manifest that the ALON–rich coupon exhibits higher impact resistance to the scale of 33.33% than that of the ALON‐free coupon. The damage assessment and CAI results annunciate the lesser damage and higher compressive strength of ALON‐rich material respectively. The micrographic study studied after the CAI reveals the delamination and failure behavior. Additionally, explicit numerical assessment was conducted to validate the experimental results. A good agreement is attained between the experimental results and numerical predictions. The enriched stiffness of the synthesized material makes it a perfect candidate for structural application where the frequency of impact loading is high.Highlights Development of ALON reinforced Kevlar‐Epoxy composites for low‐velocity impact applications.
