For decades, agricultural waste-derived natural fibers have been explored to reduce plastic waste impacts and improve management. However, fiber-reinforced composites often underperform compared high-cost synthetic fibers. This study aims enhance the performance of areca sheath fiber (ASF)-reinforced epoxy through minimal additions (3, 5, 7 wt%) low-cost thermoplastic polybutylene terephthalate monofilament (PBTM). The effects alkali-treated ASF loadings (30, 40, 50, 60 structural modifications on continuous were examined. PBTM was used fabricate ASF-reinforced with sandwich random structures. Compared composites, structures increased tensile flexural strengths by up 83% 45%, respectively. Modifying 50 wt% composite modulus (1.5 3.4 GPa), breaking energy (1.1 1.7 MJ/m3), impact strength (24.5 36.7 kJ/m2). modification also significantly enhanced thermal stability reduced water absorption, as confirmed thermogravimetric absorption analyses. Optical microscopic fractogram characterization indicated that surface treatment improved interface compatibility, while their load-bearing capacity. These findings suggest suitability PBTM-modified hybrid in construction other applications.

This study explores the influence of Zinc Oxide (ZnO) nanofluids on solar water heaters with Dimple Tubes and Helical Twisted Tape (DTHTT) surfaces. The helical twisted tape design enhances turbulence, improving nanofluid mixing thermal exchange. Computational fluid dynamics (CFD) validates efficiency parabolic trough heater (PTSWH) emphasis light concentration feed flow velocity. Optimal conditions include a 0.3% ZnO volume concentration, mass rates between 1.0 kg/min 5.0 kg/min, copper-type tapes. Experimental results reveal Nusselt number enhancements 15.1% 20.96% at H/D = 10, 16.72% 32.12% 3, for nanofluid, Reynolds numbers from 3000 to 8000. arrangement 3 exhibits increased mixing, leading higher convective heat transfer. Friction factor 8000 are 0.26% 0.38%, respectively, compared base fluid. At 3.0 rate, increases 39.25%, 13.25% gain over plain model shows ±3.24% deviation expected friction factor, total ±1.2% discrepancy experimental simulated findings, remaining within an acceptable range.

The growing demand for fiber-reinforced polymer (FRP) in industrial applications has prompted the exploration of natural fiber-based composites as a viable alternative to synthetic fibers. Using jute–rattan composite offers potential environmentally sustainable waste material decomposition and cost reduction compared conventional fiber materials. This article focuses on impact different machining constraints surface roughness delamination during drilling process FRP composite. Inspired by this unexplored research area, emphasizes influence various Response methodology designs experiment using drill bit material, spindle speed, feed rate input variables measure factors. technique order preference similarity ideal solution method is used optimize parameters, predicting delamination, two machine learning-based models named random forest (RF) support vector (SVM) are utilized. To evaluate accuracy predicted values, correlation coefficient (R2), mean absolute percentage error, squared error were used. RF performed better comparison with SVM, higher value R2 both testing training datasets, which 0.997, 0.981, 0.985 roughness, entry exit respectively. Hence, study presents an innovative through learning techniques.

This article presents the influence of hybridisation aramid and glass fibre woven fabric on fracture toughness ( K IC ) composites. Experiments using single-edge-notched-bending (SENB) were conducted to investigate effect Mode I specimen aramid/glass laminates. The results revealed that epoxy composites yielded highest , followed by hybrid composites, finally, which exhibited lowest . Fracture micrographs showed similar patterns – pullout, rupture matrix those mechanical properties being inferior suggest there is no advantage in fibres partially replace achieving
