“…The bulk density of the bamboo and groundnut shell fiber-matrix composite increased with the increase in the fiber content in the samples [35]. The difference between the initial and final rates of absorption allows the immersion specimen to measure the water uptake.…”

Current research finds the suitability of natural fiber-reinforced polymer composites for industrial, automotive, marine, aerospace, and military vehicle applications, among others; they process being lightweight, high strength, ecofriendly, recyclable, and biodegradable. Bamboo fiber (Bambusoideae) mat, groundnut shell (Cocos nucifera) powder, copper particle, and multiwalled carbon nanotubes (MWCNT) fillers with epoxy resin are the primary materials. The key responsibility of MWCNT as a nanofiller is to improve the performance of materials by more than 80% and to attract the desirable properties such as high specific energy absorption of CNTs. An extensive investigation was carried out to determine the weight ratio between the total density and the water absorption rate of the composite. The maximal tensile and flexural strengths derived from EBGCM2 (E: epoxy; B: bamboo; G: groundnut shell; C: copper particle; M: MWCNT) were 50.66 MPa and 59.03 MPa, respectively. Addition of MWCNTs to specimens EBGCM2 and EBGCM3 and bonding the filler matrix by homogeneous mixing, but few nanoparticles are seen agglomerated. Flexural abilities of groundnut fiber/filler loading to strengthen the hybrid nanocomposites and the impact strength both quite improved than EB1 specimen. The neat epoxy and bamboo fiber composite (EB1) achieved 87.5 Shore-D hardness. SEM revealed (EBGCM3) improved interfacial adhesion between fiber and epoxy resin, but few nanoparticles are agglomerated, small molecules linked between the fibrous matrix, and the binding elements trapped in neighboring atoms, forming structural chains by the polymerization process.

“…The obtained results revealed that the high values belonged to composites with 60° laminate and showed 7.4% and 5.5% for specimens immersed in distilled water and seawater conditions, respectively. 211 They also noticed that the tensile and flexural strengths decreased after being immersed in the solutions. The maximum reduction in these properties is observed in case of saline water environment.…”

“…After drying samples, the obtained results showed that 97% of tensile strength is recovered in case of composites made with glass fibers only, whereas in case of kenaf/glass hybrid composite, it is limited to 87.22%. Venkatesha B.K et al 211 investigated the moisture absorption behavior of woven bamboo/glass fiber-reinforced epoxy hybrid composites with different laminate orientation. The volume fraction of fibers within composite specimens ranges between 31.71% and 32.52%.…”

“…This is explained by the physical damage or chemical deterioration that specimens exhibited. 211 Chittaranjan Deo and Acharya 212 investigated the moisture adsorption behavior of lantana camara fibers reinforced epoxy composites at different fiber contents and environmental conditions (steam, saline water and sub-zero temperature). They found that the moisture adsorption increases by increasing the fiber content within composites.…”

To meet the growing demand for the use of environmentally and friendly materials in various applications, many efforts have been done in order to provide lighweighting, biodegradable, and renewable composites leading to a diminution of greenhouse gas emissions. However, they are confronting some challenges that may limit their utilization in industries such as poor interfacial adherence, high moisture absorption, low processing temperature, and impact strength. Several research works have been carried out regarding the mechanical, thermal, and hydric properties of natural fibers reinforced composites to deal with above underlined drawbacks. Actually, based on our analysis, there are two relevant concerns that prevent their integration in other industries such as marine and renewable energy sectors. In this context, the current critical review offers an up to date overview of the factors influencing the properties of the different components of natural fibers composites (fiber, matrix, fiber/matrix interface) as well as their physicochemical, mechanical, thermal and hydric behaviors. Recent works on the mechanical properties of nanobiocomposites based on cellulosic fibers, crystals, and nano-clay fillers are reviewed. The future directions are also discussed to overcome the challenges confronted by these materials, that is, fire resistance and moisture absorption, in order to widespread their utilization especially for wet and fire retardant purposes.

In this paper, a short review on the void and moisture content studies of fiber reinforced composites for both, synthetic and natural based fibers are presented. The review summarized the research papers in which include experimental and theoretical works that related to the void and moisture content studies. In addition to that, this review paper highlighting a few research studies conducted in literature on the effects of the void and moisture on the mechanical performances of the composite. Few common measurement methods used for the void and moisture determination are discussed here. The aims of this short review, mainly to capture the trend ranging from the recent five years back and summarize the various studies and also to compare and conclude the most common method for the determination of the void and moisture content. This paper is mainly providing a baseline in the selection of the methods for the future work of the author’s work with regard to the reduction of the presence of voids and moisture occur during the impregnation process of fiber reinforced composites, especially when using natural-based fiber.
