“…In Figure 2, it appears that the tensile and flexural strength, measured according to ASTM D790 [25] and ASTM D638 [26] standards, respectively, degrade for both loading modes when the amount of filler exceeds 40 wt.% [27]. Another study indicated a steady increase in impact strength (measured according to ISO179 standard [28]) for up to 30 wt.% TSP filler content in epoxy, ground to dimensions between 200 and 300 microns, with very limited increase in water absorption, not attaining 2% after 12 days [29]. Among the plethora of eco-friendly composites, one particular area of interest lies in the incorporation of seed as fillers, hopefully able to work as reinforcements, into composite matrices for the production of compostable (disposable in the organic fraction of waste) materials, therefore with limited amount of ligneous fillers, yet also for obtaining more durable materials with limited water absorption [24].…”

With the growing concerns over environmental degradation and the increasing demand for sustainable materials, eco-friendly composites have gained considerable attention in recent years. This review paper delves into the promising realm of seed-based fillers, reinforcements and polysaccharidic matrices in the production of biocomposites that are yet focusing on those seeds, which can be considered industrial process waste. Seeds, with their inherent mechanical properties and biodegradability, which are often the waste of production systems, offer a compelling solution to reduce the environmental impact of composite materials. This paper explores the properties of various seeds considered for composite applications and investigates the processing techniques used to incorporate them into composite matrices. Furthermore, it critically analyzes the influence of seed fillers on the mechanical and physical properties of these eco-friendly composites, comparing their performance with traditional counterparts. The environmental benefits, challenges, and limitations associated with seed-based composites from waste seeds are also discussed, as well as their potential applications in diverse industries. Through an assessment of relevant case studies and research findings, this review provides valuable insights into the outlook of seed-based composites as a sustainable alternative in the composite materials landscape, emphasizing their role in promoting a greener and more responsible approach to materials engineering.

“…Naik et al 13 performed an investigation on the mechanical properties of tamarind seed particles reinforced composites. Results showed that the tensile strength of the composite was seen as 27.69 MPa and young's modulus of the composite was observed as 362.39 MPa while adding 10% and 20% of seed particles respectively.…”

Features such as environment friendly and low cost attract the industrialists toward natural composites. The utilization of agricultural wastes in the manufacturing of natural composites expands its usage in several industrial applications. Hence, the research on the extensive usage of agricultural wastes is still required. Consequently, in this research, an attempt has been made to fabricate the natural composites using the agricultural wastes like Indian almond fruit and neem seed. Indian almond fiber was extracted from the fruit and neem seed were converted into powder form. Composite was prepared by conventional hand layup technique. The fiber quantity was kept as constant and neem seed particle (NSP) volume fractions were varied from 2.5 to 10 wt%. Mechanical tests like tensile, flexural, impact and hardness were determined. Results indicated that the fiber and NSP showed good reinforcement effect. The Indian almond composite (IAC) with 7.5 wt% NSP, that is, IAC/7.5 wt% NSP composite, exhibited the better mechanical properties. Further, the IAC/10 wt% NSP composite displayed the less water absorption and least degradation. This study suggests that the IAC/7.5 wt% NSP composite could be used in industrial applications due to its good mechanical properties.

Recently, natural filler reinforced polymer composites are important materials for various engineering applications. Hence, this present work focuses on utilization of Cocos nucifera shell powder (CNSP) as a filler in vinyl ester (VE) resin to produce particulate composite specimens. The particulate composite plates with various weights or filler contents from 5 to 30 wt.% were fabricated, using compression molding technique. The fabricated composites were subjected to tensile, flexural, impact, hardness, heat deflection and swelling behavior tests to obtain their corresponding material properties. Energy dispersive X-ray (EDX) analysis was carried out on the Cocos nucifera shell powder/vinyl ester (CNSP/VE) composite specimens to investigate into the presence of their elements, in addition to the aforementioned tests. From the experimental results obtained, it was observed that the optimum mechanical properties of CNSP/VE composites were obtained at 15 wt.% of filler content, having tensile, flexural and impact strengths of 38.70, 105.13 MPa and 33.04 kJ/m 2 , respectively. Also, the heat deflection temperature (HDT) results varied from 158 (0 wt%, neat VE resin) to 171 o C along various percentages of filler contents. Lastly, the morphological study/analysis of the fractured CNSP/VE composite specimens was conducted by using a scanning electron microscope (SEM) to confirm the experimental data/results obtained. It was evident that CNSP/VE composite structures could be potential substitutes for some synthetic composites. Also, they are suitable for various engineering applications in aerospace, electrical/electronics and automobile industries, based on their properties.
