“…Furthermore, it was suggested that the rise in tensile modulus and the fall in impact strength of the NFPCs with clay fillers were as a result of the polymer matrix improved cross-link density, which led to a decrease in the stiffness of the composite, hence reduced the impact strength [130,133]. While in other studies, aluminum powder was used as fillers and in others, modified clay improved the impact strength of the composite, as the SEM micrographs revealed the existence of less voids and rise in density along with improvement in stiffness resultant from better interfacial adhesion amongst the fiber and the matrix in the presence of the modified clay [134,135]. Other advantages of filler addition to sisal fiber reinforced polymer composites are increased moisture absorption or reduced water uptake as reported by [135,136].…”

Fiber-matrix interaction at the interphase is one very important property that is of great concern to all polymer scientists involved in polymer composites. Many of the failures can be traced to the type of interfacial interaction existing in the composites. That is why highlighting the factors that dictate the type of and the extent of interactions at the interphases become very necessary. Natural fiber polymer composites have found application in many fields of human endeavors. To continue this growth being experienced, the factors that determine the formation of good interaction at the interphase most be understood, so that they can be manipulated for a better result.

“…Polymer composites are a kind of customized material, designed from a combination of two or more material Polymers have easy processing, high productivity, and reduced costs. In most applications, polymers are modified using additives and fibers to meet different mechanical, electrical and thermal requirements [4][5][6][7]. Polymer composites are a kind of customized material, designed from a combination of two or more material phases, including matrix and dispersed phases.…”

“…Polyols with molecular weight (MWt) in the range of 1,000-6,000 and functionality values (the average number of -OH groups) between 1.8 and 3.0 are usually used to fabricate flexible PU foams and elastomers. High cross-linked rigid PUs are synthesized using short chain polyols (MWt < 1000) with high functionality (3)(4)(5)(6)(7)(8)(9)(10)(11)(12) [19].…”

In this study, microcellular polyurethane (PU)-natural fiber (NF) biocomposites were fabricated. Polyurethanes based on castor oil and PMDI were synthesized with varying volume ratios of sisal fiber. The effect of natural fiber treatment using water and alkaline solution (1.5% NaOH) and load effect were investigated. Biocomposites were mechanically and physically investigated using tensile, viscoelasticity, and water absorption tests. The interfacial adhesion between PU and sisal fiber was studied using SEM. Short NF loads (3%) showed a significant improvement in the mechanical properties of the PU-sisal composite such as modulus of elasticity, yield and tensile strength up to 133%, 14.35 % and 36.7% respectively. Viscoelastic measurements showed that the composites exhibit an elastic trend as the real compliance (J’) values were higher than those of the imaginary compliance (J’’). Increasing NF loads resulted in a decrease of J’. Applying variable temperatures (120–80 °C) caused an increase in the stiffness at different frequencies.

“…The most important advantages of natural fibers relate to environmental issues: they are biodegradable and carbon positive, since they absorb more carbon dioxide than they produce [5], [11]. Other important advantages are shown in terms of specific material properties: using natural fibers in place of synthetic ones, it is possible to reduce the weight of a composite material by up to 40 %, and it is also possible to improve flexural strength, stiffness and ductility [6].…”

The importance of natural fiber reinforced composites is rapidly developing both in terms of engineering application and research field. The aim of this investigation is conducting an experiment to obtain the water absorption, physical and Mechanical properties of hybrid composite was fabricated from (False Banana Fiber) FBF and (Sisal Fiber) SF through general purpose (GP) resin-hardener mixture. The samples fabrication procedure was carried out by varying FBF and SF weight ratio to see its effect of mechanical and physical properties. Three samples (FBF: SF) i.e., 1:1 ratio, 3:1 ratio and 1:3 ratio with ply orientation as the reinforcement material. Then, tensile strength, compression strength, flexural strength water absorption percentage and density was conducted according to ISO and ASTM standards. The results show that the overall tensile strength shows a 1:3 ratio have shown 69 MPa which are higher than 1:1 ratio and 3:1 ratio. 3:1 ratio. In a compression strength test also 12.30 MPa which was higher result is obtained from 3:1 ratio. For both flexural(bending) strength and water absorption (for ordinary tap water and rainwater) test 380 MPa and (2.64 % and 3.07 %) respectively resulted, which are relatively less than from 1:1 ratio and 3:1ratio.
