“…Water-soluble materials begin to leach from fiber, and finally lead to ultimate debonding between the matrix and fiber. The aforementioned diffusion mechanism of water molecules into the natural composite structure is illustrated in Figure 1 [18][19][20][21][22][23][24][25]. The moisture absorption causes all three dimensions of the laminated composite to increase.…”

Natural composites can be fabricated through reinforcing either synthetic or bio-based polymers with hydrophilic natural fibers. Ultimate moisture absorption resistance at the fiber–matrix interface can be achieved when hydrophilic natural fibers are used to reinforce biopolymers due to the high degree of compatibility between them. However, the cost of biopolymers is several times higher than that of their synthetic counterparts, which hinders their dissemination in various industries. In order to produce economically feasible natural composites, synthetic resins are frequently reinforced with hydrophilic fibers, which increases the incompatibility issues such as the creation of voids and delamination at fiber–matrix interfaces. Therefore, applying chemical and/or physical treatments to eliminate the aforementioned drawbacks is of primary importance. However, it is demonstrated through this review study that these treatments do not guarantee a sufficient improvement of the moisture absorption properties of natural composites, and the moisture treatments should be applied under the consideration of the following parameters: (i) type of hosting matrix; (ii) type of natural fiber; (iii) loading of natural fiber; (iv) the hybridization of natural fibers with mineral/synthetic counterparts; (v) implantation of nanofillers. Complete discussion about each of these parameters is developed through this study.

“…All polymers and polymer based composites absorb moisture in humid atmosphere when immersed in water. In general, moisture diffusion in composites depends on factors such as the volume fraction of fibre, void volume, additives, humidity, and temperature [14][15].…”

Fiber reinforced polymer composites have been used in a variety of applications because of their many advantages such as relatively low cost of production, easy fabrication etc., . Reinforcement in polymer is either synthetic or natural. Synthetic fiber such as glass, carbon etc. have high specific strength but their fields of application are limited due to higher cost of production, and due to their non biodegradability. Recently there has been an increased interest in natural fiber based composites due to their many advantages, like biodegradability. Coir & banana fibre are used in the present work for making natural fiber reinforced composite. The objective of the present research work is to study the mechanical behavior of coir& banana fiber reinforced polyester based hybrid composites and comparison of properties like young's modulus. The optimum percentage of banana fiber and coir are found by conducting response surface Methodology.

“…For example, polyester‐type organic fibers can be hydrolyzed easily at high temperatures and in a humid atmosphere, steel fibers can become rusty in high humidity, and the surface of fiberglass can show more micro‐cracks at high temperatures and in a humid atmosphere. The diffusion of water vapor through the polymeric coatings to the interface between the fiberglass and primary coating governs the strength of the fiberglass 12–15. Such fiber degradation greatly influences the application lifetime of fiber‐reinforced rubber products.…”

p-alkylphenol-resorcinol-formaldehyde-latex (ARFL) films were prepared by co-condensation of p-alkylphenols and resorcinol with formaldehyde to generate modified phenolic resins, followed by blending with rubber latex, aging, and finally curing. The weight-gain of the ARFL films and the tensile force of the coated fiberglass were studied under different temperatures and various humidities. The surfaces of the ARFL films were further analyzed by measuring the static contact angle and the findings were confirmed by Fourier Transform Infrared Spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis. The adhesion between the coated fiberglass and neoprene rubber was evaluated using the H-adhesion technique. The best hydrophobicity and the largest water contact angle were displayed on the surface of the p-nonylphenol-resorcinol-formaldehyde-latex (NRFL) film, with a weight-gain percent that was 40.0% (wt %) lower and a static contact angle that was 22.6 more than that of the resorcinol-formaldehyde-latex (RFL) film. The NRFL-coated fiberglass had a higher tensile force and H-adhesion force than the RFLcoated fiberglass. The shelf life of NRFL-coated fiberglass can be raised significantly at 40 C and under 98% humidity. The mechanism of the dramatic drop in the tensile force of the coated fiberglass is also discussed.
