Abstract Epoxy-based composites, valued for their cost-effectiveness and remarkable mechanical properties, attract considerable attention from researchers in academia industry. This study explores the impact of low concentrations (1% to 3%) walnut shell (WS) talc additives on density, water absorption, (tensile, three-point bending, impact, hardness) as well thermal (TGA, DSC) properties epoxy composites. While prior research has extensively covered composites with high talc, utilization lower remains underexplored. Findings highlight substantial influence incorporating percentages Tg temperatures reducing temperature WS elevating it. TGA tests reveal that both contribute increased Tmax residue content compared pure epoxy. Mechanical exhibit variations based filler type amount, enhancing elastic modulus decreasing it Impact resistance sees significant reductions related particle size. Talc boosts while a more pronounced effect hardness. Water absorption demonstrate higher WS-containing Glossiness surface roughness undergo changes, increasing glossiness. In conclusion, even minor noticeably composite epoxy, providing avenues customized modifications, particularly challenging or costly fillers, offering viable alternatives diverse fields.

The growing production of glass fibers is a major challenge due to the later problem their sustainable recycling. This article reports potential use post-production waste and basalt powder as additives in resin compounds designed for repairing concrete elements. aim this research was develop repair compound based on epoxy with addition materials, offering competitive alternative currently available market by utilizing lower-cost materials addressing pro-environmental aspects through reuse. prepared samples were characterized varying proportions (0–20%), ground HP 12 (40/60%), 6 (10/20%). A series tests, including tensile strength conducted part study determine effect applied ultimate force maximum deformations. Abrasion resistance tests also carried out evaluate impact filler enhancing abrasion compound. Additionally, SEM EDS analyses used uniformity distribution within sample. examined containing percentages fibers, both virgin milled. most significant reinforcement observed sample E/20HP/20bp, where its decreased 8%, while increased 44% compared reference obtained results confirm that incorporating into can significantly enhance mechanical properties reducing cost promoting environmental protection. In addition, developed complies selected principles 6Rs regulations: RECYCLING (reuse fibers), RETHINK (reduce avoiding landfill), REDUCE (minimize compounds) REPAIR (increase efficiency damaged structures). Furthermore, percentage increases, improves. may serve an bridges factory floors.

The aim of this study is to investigate the potential using walnut shells, which are agricultural waste, in polymer composites order reduce environmental impacts and contribute production sustainable materials. In direction, Flame Retardant Polyester (FRP) was used as a binder composite materials, while standard CEN sand Waste Walnut Shells (WWS) were filler While creating mixture groups, FRP preferred at 50% 50%. Then, keeping ratio constant, WWS replaced by 25%, 50%, 75% 100% volume. apparent density, water absorption, porosity, ultrasonic pulse velocity (UPV) compressive strengths produced investigated. specimens where with sand, decrease 27%, 20% 28% detected strengths, UPV density values, respectively, compared control specimen. most negative behavior terms absorption observed specimen coded WS75 rate 0.80%. use evaluated an economical raw material source, contributes prevention pollution also important its be recycled into economy.
