Natural fibers have played a significant influence in research materials and engineering industries because of Its unique properties compared to synthetic fibres. Natural fibers' desirable qualities, such as low density and cheap cost, high toughness and degradability, make them ideal for use as a reinforcement in polymer compounds. Furthermore, as compared to natural fiber composites, synthetic fibers such as glass or carbon fiber Pose health hazards for workers who labor in the manufacture of their comparable composite materials [1]. Palm oil Empty Fruit Packet (OPEFB) is mass-produced after extraction Palm oil from fresh fruit clusters. OPEFB is composed of 54% cellulose, 28% hemicellulose, and 17.6% lignin. Because of their recyclable, renewable, and limitless qualities, OPEFB fibers with a high cellulose content are more desired Cellulosic biomass [2]. Researchers and engineers are Tend to the use of OPEFB fibers for industrial applications because they are biodegradable and renewable, with minimal energy consumption during processing, and are also more ecologically friendly and less expensive than synthetic fibers [3]. Electronic gadgets, paints and adhesives in the aerospace and automotive industries As a result of its thermal and electrical superiority and mechanical capabilities, ERs are extensively employed in the construction of Compounds reinforced with natural fibers and in the creation of a wide range of industrial goods [4].
Dielectrics are poor conductors of electricity but are excellent supporters of electrostatic fields, and are therefore used in capacitors. In this case, the improved relative permittivity (as defined in ASTM D150) allows the same charge to be kept in a smaller electric field or using a lower voltage. As a result, the capacity increases. Of course, when charging, the dielectric absorbs electrical energy, which is referred to as dielectric loss: losses should be minimal at the capacitor's service frequency [5]. Researchers are shifting away from synthetic polymers and tend to biodegradable polymers such as cellulosic or natural fiber-based molecules. It is particularly appealing for sustainable technology development due to its minimal environmental effect, biodegradability, adequate specific strength, low density or light weight, low cost, and ease of recycling. These are used in a variety of disciplines, including biocomposites, and have been widely used in food packaging, energy storage material, biomedical sensing, and sustainable energy harvesting system [6, 7].
Because of their high thermal conductivity, reinforced composites are a good choice for producing highly thermal conductive polymer-based composites. The thermal conductivity of a composite is affected by its form, size, and contaminants. Purification is required to generate well-structured composites with good thermal conductivity. Thermally conductive polymer composites provide up new possibilities for substituting metal elements in a variety of applications. [8]. It is worth noting that the use of high thermal conductivity nano-fills is now being researched as a method to increase the thermal conductivity of polymers. To improve the thermal properties, the volume fraction and fiber distribution will be more important than the choice of polymer materials. The thermal conductivity of the compound varies with the temperature and orientation of the fibers. Moreover the quantum frequency of atomic vibrations is represented by phonons. Thermal energy is transferred by phonons through interactions between them and subatomic particles. Phonon scattering also occurs in multiphase polymer nanomaterials as well, and diffuses from one phase to the next. Accordingly, the thermal conductivity of compounds is also affected by the composition, size and geometry of the molecules [9].
M. Jawaid et.al[ 10 ] used oil palm empty fruit bunch (EFB) fibres, jute fibres and oil palm EFB/jute fibre reinforced epoxy hybrid composites in different layering pattern at EFB: jute ratio (50:50) fabricated by hand lay-up technique. The thermal conductivity of epoxy matrix, oil palm EFB, jute and oil palm EFB/jute hybrid reinforced epoxy composites has been evaluated by Hot Disk. Obtained results indicated that thermal conductivity of epoxy matrix increased with reinforcing of oil palm EFB and jute fibres. Hybridization of oil palm EFB with jute fibres allows an increased in thermal conductivity of oil palm EFB/jute hybrid composites. We concluded that oil palm EFB/jute hybrid composites can be used for thermal applications in automotive and construction industry to save energy
Yao et al.[11] In his study, found that studying the effect of the presence of different nanoparticles, such as MgO and TiO2, regardless of the supported material, the permittivity of the dielectric increased with the increase of the nanomaterials content of the compounds.
In this work, samples of reinforced epoxy compounds were prepared using epoxy resin as a polymer matrix and palm oil fibers as organic fillers, and extracting the above, which is expected to improve thermal insulation and dielectric constant and maintain its resistance to insulator breakdown for composites. So palm oil fibers in epoxy resin matrix can provide effective insulation. In addition, the interaction between the filler and the epoxy matrix is analyzed to explain the improvement of insulating properties and heat transfer performance.
