The current study aims to examine the influence of surface‐modified micro‐sized walnut shell particulates (WSP) with an aqueous solution of sodium hydroxide (NaOH) on epoxy composites. For that, epoxy/WSP composites are prepared by varying the WSP content up to 20 wt%. In this investigation, the physical properties (surface morphology, density, voids percentage, water uptake), mechanical properties (tensile, flexural, compressive, hardness), and sliding wear behavior of the composites are reported. From the micrographs, it is clear that WSP established good adhesion with the epoxy matrix. Further, it is found that the density, void content, water intake capacity, compressive strength, and hardness increase with WSP loading. Against that, the tensile and flexural strength is somewhat reduced at higher filler loading. Sliding wear tests are performed as per L25 Taguchi's orthogonal array. From the analysis, it is observed that WSP content is the most significant factor and sliding distance is the least significant factor for minimizing the wear rate. For analyzing the sliding wear performance under varied conditions, a prediction model is proposed using an artificial neural network to forecast the sliding wear rate of epoxy/WSP composites over a wide range of experimental domains.

“…The use of walnut filler with a natural fiber or synthetic fiber gives fruitful results leading to its future scope of a substitute hybrid composite reinforcement [21]. The size of the filler has a crucial part to play which varies from 75 micron to 150 micron to have a significant strong bonding with the polymer matrix [22]. Although a lot of work has been done in walnut filler polyester composite.…”

In this article, an experimental investigation has been performed to examine the mechanical behaviour of walnut shell powder filled-glass fiber reinforced vinyl ester composite. The size of walnut shell varied in the range of 80 micron to 120 micron. Glass fiber was reinforced in mat form to provide primary strength to the composite while walnut shell powder (WNP) was used in view of giving value addition to it. Weightage of glass fiber was kept constant at 10 wt. % while WNP was varied as 0, 10, 15 and 20. Composite was fabricated by conventional hand lay-up method and characterized for mechanical propertied such as tensile strength, flexural strength and impact energy. The obtained results revealed that incorporation of WNP has significant influence on the mechanical properties but at higher weightage of WNP, a slight reduction in the properties were observed except flexural strength which showed linear increase with the addition of WNP.

“…Se manifestó como el uso de partículas de origen orgánico como por ejemplo partículas lignocelulósicas dio paso al desarrollo de los "Wood plastic composites". Este campo tiene también su área de aplicación dentro de los materiales termoestables [183], así también como los denominados "particle boards" (PB), aunque el uso matrices termoestables de origen petroquímico sigue siendo preferente [102,184]. Pero con el avance que se ha conseguido en los últimos años en el desarrollo de matrices termoestables de origen natural como los derivados de aceites vegetales, han servido de incentivos para que varios investigadores dediquen su tiempo en el estudio y desarrollo de materiales compuestos basados en matrices de origen natural.…”

The concern that has arisen in recent years over the excessive use of oil-based materials has made the development of new materials with low environmental impact imminent, in this context. In this study, eco-friendly compounds were produced with a thermoplastic poly (lactic acid) matrix (PLA)and jute fibers (woven and non-woven) as reinforcement. PLA/jute bio-composites were manufactured by hot-press molding. The effect of the amount of jute fibers reinforcement (in the 30-50 wt. % range) on the tensile and bending properties of bio-composites was analyzed, and the fiber-matrix interaction were assessed by scanning electron microscopy (SEM). The results suggest hot compression moulding is a simple technique to obtain high environmental efficiency biocomposites with high reinforcement loading (up to 50 wt. %). As expected, the tensile properties are directly related to the amount of fiber loading, as well as the directionality that the fibers have in the composite. Mechanical performance is also highly dependent on fiber-matrix interactions. These bio-composites could be attractive as substitutes for conventional composites and/or engineering plastics.
