“…It was found that adding 50% banana fiber in to Jute epoxy composites enhanced its thermo-mechanical characteristics while reducing moisture absorption. 14 According to many authors, [15][16][17][18][19][20] the impulse hammer vibration testing method has the potential to be a quick and accurate approach for detecting intrinsic material properties, as well as quality assurance and monitoring. Satish Pujari et al 21 developed and successfully assessed Jute and banana fiber thermal conductivities as a function of volume percent.…”

The primary purpose of this study is to realize quantitative fiber loading effects on free vibration, damping behavior, fracture toughness, thermal conductivity, inter-laminar shear strength, and flammability of jute-banana fiber phenolformaldehyde (PF) hybrid composites. These composites were manufactured with fiber weight percentages ranging from 30% to 60% using hot press technique. Hybrid composite with equal amount of fiber and resin (PJB-2) had a higher natural frequency in the range of 4.8%-59%, a higher inter-laminar shear strength varying from 30% to 54%, a higher fracture toughness with minimum of 19 to maximum of 44%, and a low damping factor in the range of 25%-59% to that of other composite having unequal amount of fiber and resin loading. In contrast to other composites, the composite containing 30 wt% fiber (PJB-4) has a high heat conductivity of about 10%-20%. However, the thermal conductivity of jute-banana fiber PF composites declined as the fiber content increased beyond 30 wt%, while the flame resistance was improved as the resin concentration increased. Additionally, Scanning electron microscopy (SEM) studies clearly indicates the failure patterns of fiber matrix interface under Inter laminar shear strength and fracture toughness tests were supports to justify the experimental results.

Sustainable fiber reinforced polymer (FRP) composites from renewable and biodegradable fibrous materials and polymer matrices are of great interest, as they can potentially reduce environmental impacts. However, the overall properties of such composites are still far from the high-performance conventional glass or carbon FRP composites. Therefore, a balance between composite performance and biodegradability is required with approaches to what one might call an eco-friendly composite. This review provides an overview of sustainable FRP composites, their manufacturing techniques, and sustainability in general at materials, manufacturing, and end-of-life levels. Sustainable plant-based natural fibers and polymer matrices are also summarized, followed by an overview of their modification techniques to obtain high-performance, multifunctional, and sustainable FRP composites. Current state-of-the-art mechanical and functional properties of such composites are then surveyed, and an overview of their potential applications in various industries, including automobile, aerospace, construction, medical, sports, and electronics is provided. Finally, future market trends, current challenges, and the future perspective on sustainable natural FRP composites are discussed.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adsu.202200258.

“…As a result, with the increase in fiber content, the thermal conductivity of natural fiber-based composites decreased. 21 Pujari et al 110 investigated the thermal conductivity of jute fiber/epoxy and banana fiber/epoxy composites using a hand lay-up technique and reported that the thermal conductivity of composites decreased with the increase of natural fiber content. They also reported the thermal conductivity of composites at the maximum volume fractions of jute and banana fiber-reinforced composites at 0.231 and 0.228 W/m-K in the temperature range of −20°C–300°C, respectively.…”

“…Along with degradation at lower temperatures, thermal stability in particular service ranges can be compared. 110 Mofokeng et al 117 studied the thermal behavior of natural sisal fiber (SF) reinforced, SF/PLA and SF/PP biocomposites by TGA and differential scanning calorimetry (DSC) analysis. The study observed that the thermal stability of biocomposites improved significantly with the increase of fiber content percentage compared to both neat polypropylene (PP) and poly (lactic acid) (PLA).…”

The growing awareness of socioeconomic and environmental issues and the high percentage of petroleum resources consumed and new environmental regulations have fueled efforts to develop innovative, cutting-edge, environmentally friendly materials with a wide range of applications. Due to environmental and sustainability concerns, the advancement of biocomposites has resulted in tremendous breakthroughs in green materials in this century. Their primary goal is to replace current synthetic petroleum-based composites with natural resources. Materials derived from nonrenewable petroleum-based sources are hazardous and expensive to produce; on the other hand, biocomposites derived from natural sources are biodegradable, recyclable, non-abrasive, and compostable and have properties comparable to synthetic fiber composites. Natural fibers are low-cost, lightweight, biodegradable, renewable, and environmentally friendly alternatives to synthetic fibers like glass and carbon fiber. The long-term viability of natural fiber-based composite materials has led to increased use in various production industries. However, the manufacturing process of natural fiber-based biocomposites is still plagued by some difficulties, such as poor adhesive propensity, moisture absorption, poor fire resistance, low impact strength, and low durability. This review provides a panoramic view to provide insight into different aspects of biocomposites based on natural fibers and polymers in terms of properties and applications, which will pave the way for future biocomposites research in academic and commercial contexts.
