“…Generally, the treated filler-matrix showed better results as compared to untreated and unfilled composites, which are in accordance with the literature [40]. The typical stress-strain curves for the brittle and ductile natures for uniaxial compression testing are illustrated in the literature [41].…”

The current study deals with the effective usage of Portunus sanguinolentus shell, which is a solid waste in the seafood industry. This Portunus sanguinolentus shell waste was powdered and used as untreated fillers in jute fabrics reinforced epoxy composites. Then Portunus sanguinolentus shell waste powder was treated with chemicals to perform fat removal, deproteination, decarbonization and deacetylation to obtain treated Portunus sanguinolentus shell filler. Three different composites were developed with traditional hand layup process consisting of four layers jute fabrics that were filled with 10 wt% untreated Portunus sanguinolentus shell filler, chemical treated 10 wt% Portunus sanguinolentus shell filler and unfilled one. The thermo-mechanical and fracture morphologies were assessed by tensile, flexural, compression, shear, impact, hardness thermogravimetric analysis, Fourier-transform infrared spectroscopy and scanning electron microscopy analysis. The results showed an increase in the thermo-mechanical property of chemical-treated Portunus sanguinolentus shell powder-filled jute fabrics-based epoxy composite. This phenomenon is due to the increase in the chitosan, mineral contents and decrease in the organic content in the Portunus sanguinolentus shell powder due to chemical treatment, thus enhancing the bonding between the filler and fiber matrix with reduction of the void. A showcase stand was developed with the best performer, as an attempt in the perfection of application. The application is then analyzed using ANSYS to predict the deformation behavior when subjected to 0.25 kg, 0.5 kg and 1 kg loads.

“…In a more recent work, chemically treated and untreated bagasse fibers (1–5 mm in length) were used as reinforcement (10%) for epoxy with calcium carbonate (CaCO 3 ) as filler (2 and 4%) . Bagasse fibers used had a cellulose content of 42%, hemicellulose content of 28% and lignin content of 22%.…”

Composites are primarily made using matrix and reinforcement as major components but may also contain several other fillers or additives. A majority of the composites are made using synthetic fibers and polymers. However, in the last few decades, focus has been on developing biocomposites using renewable resources. Conventionally, biocomposites are developed using natural fibers such as jute, Kenaf, or Ramie as reinforcement and synthetic resins such as polyethylene, polypropylene and epoxy as matrix. Typically, biocomposites contain either the reinforcement or matrix which makes the composites partially degradable. Such partially degradable composites provide good properties, but the presence of a nonbiodegradable component, particularly as a matrix limits their biodegradability. Alternatively, composites that contain both the matrix and reinforcement from renewable resources which make the composites completely degradable have also been developed. However, these completely biodegradablebiocomposites do not have the desired mechanical properties and stability at high humidities or in aqueous environments which restricts their application. In addition, natural fibers and resins used in biocomposites have inherent limitations and also not easily processable. To overcome limitation of using a single reinforcement or matrix derived from bioresources, hybrid composites that contain more than one reinforcement or matrix are developed. Such hybrid composites are manufactured by either intimately mixing two or more fibers or other reinforcing materials or by placing different layers of the reinforcement and molding them into composites using one or more resins. Conventionally, hybrid composites refer to metallic and ceramic based reinforcement, matrix and fillers. Although hybrid biocomposites are gaining significant attention, the presence of multiple reinforcements and/or matrix makes it difficult to process and also to predict the properties of such composites. Hence, understanding the properties and potential of using multiple reinforcements and/or matrix materials from renewable resources to develop biobased hybrid composites is highly desirable. This article discusses hybrid composites that contain a major proportion of renewable materials. Hybrid composites not only provide better properties but could also lead to substantial cost reduction due to the incorporation of inexpensive raw materials. These composites show potential for use in aeronautical, sporting goods, wind power turbine blades, helmets and civil construction such as pedestrian bridges and many other applications. This review provides an overview of the biobased materials used to develop hybrid composites, their processability and their potential applications. POLYM.

“…In a comparison of the untreated and NaOH chemically treated bagasse reinforced epoxy composites, the chemical treatment imparted the composites better mechanical properties in terms of flexural strength, ultimate tensile strength and compression strength (39). Sulphuric acid followed by NaOH pretreated bagasse fibers were applied to ethylene vinyl acetate (EVA) copolymer in combination of titanium dioxide (TiO 2 ) nanoparticles.…”

“…Alkali and acid treatments are common solvents to treat fibers. Fibers such as wheat straws (38), cornhusks (16) and bagasse (39) would have better adhesion to the matrix due to the removal of noncellulosic materials in fiber after treatments. Enzyme treatments also improve interfacial adhesion for wheat straws by producing finer fibers and increasing the fiber aspect ratio (40,41).…”
