“…Non-organic materials have also been proposed for skin simulant research, including industrial silicones and polyurethanes [2,9,[12][13][14][15][16]. Being non-human or animal sourced, the use of these materials obviates the need for ethics and their mechanical behavior and properties can be studied in a more controlled manner.…”

“…The similar kind of increase in strength was recorded in the past as well. 24 -26 The reason for the better result in the strength is that the fillers carried out the stresses in the loaded material by way ‘elastic matrix – rigid filler’, resulting the perfect reinforcing function. The increasing of filler concentration generally leads to growth in strength until some limiting content.…”

In recent times, polymer composites have played an epochal role in transforming material science. Some of their properties such as toughness, strength, flexibility and rigidity have helped them supplant conventional materials such as iron, steel, and aluminium on several occasions. Apart from this, they are light in weight and more cost-efficient, which make them a viable alternative. They have found their application in several fields such as automobile industry, aerospace industry, construction and pipeline industry. Owing to its excellent impact strength, tensile and hardness, natural fibres serve as an excellent replacement. Natural fibres are an environmental friendly, biodegradable and are readily available. The present investigation uses a new fibre for manufacturing the eco-friendly composite material. Mechanical properties such as tensile strength, shear stress, flexural rigidity, impact strength and hardness of a coconut fibre-reinforced polymer composite material are evaluated as per respective ASTM standards. A surface analysis of the material using a scanning electron microscope is also performed. The results are categorized and tabulated accordingly. The values obtained appear to fall in line with the experimental data and hence can be espoused as an alternative material especially in the automotive sector.

“…There are many popular nonlinear hyperelastic material models: Mooney-Rivlin [24], Ogden [25], Arruda-Boyce [26], Yeoh [27], Gent [28], and NeoHookean [29]. These models have been used to model soft materials [30][31][32][33]. All these characteristic models well suit the unfilled rubber materials that elongate in the range of 100 to 700.…”

The aim of this paper is to study the high load of multiwall carbon nanotubes (MWCNTs) in natural rubber (NR) matrix. Firstly, the rubber matrix, fillers, and crosslinker are thoroughly mixed together in two-roll mill. Rheological tests are done from which scorch time, cure time, and cure index are estimated. The kneaded mixer is then compression molded, dumb bell samples as per ASTM D412 are prepared, and tensile strength, tensile modulus, elongation at break, and hardness are measured. It is noticed that NR/30% MWCNT has shown the highest tensile strength of 23.38 MPa and Shore A hardness of 90, which is 78.18% and 91.5%, respectively, higher than the unfilled NR. The increase in strength and hardness, the ductility loss, and decrease in elongation at break are observed upon increase in filler. FTIR, SEM, and AFM examinations are done and the results show high dispersion of nanofillers and strong interfacial interaction with rubber, which is responsible for overall enhancement in mechanical properties of the nanocomposites. Furthermore, the nonlinear material constants are evaluated through extended tube model and corresponding nonlinear material constants of different filler compositions are presented for the designers to use them in their component design and analysis.
