“…The density of the composite from this study is about the same as the density of coconut shell composites from previous studies by Singh et al [ 15 ] and Bhaskar et al [ 39 ]. Comparing to the rice straw composite [ 37 ], the density of the coconut shell composite is much higher than the density of the rice straw composite.…”

Conventionally, panel boards are produced with material flex or microparticle with P.U. or U.F. as adhesives. However, in this study, nanoparticle with epoxy resin as an adhesive was used to produce nanoboard. Coconut shell nanoparticle composite with epoxy resin as an adhesive was prepared using a compression molding technique. The coconut shell particles were originally 200 mesh size and then milled mechanically with a ball mill for the duration of 10, 20, 30, and 40 h (milling times) to produce nanoparticles. The composition ratio of the composite is 85 vol.% of coconut shell and 15 vol.% of epoxy resin. The formation of nanoparticles was observed with transmission electron microscopy (TEM). The mechanical, physical, and microstructure properties of the composite were examined with X-ray diffraction, scanning electron microscopy, atomic force microscopy, and universal testing machine. The results established that the properties of the composite (microstructures, mechanical, and physical) are influenced by the duration of milling of coconut shell particles. The modulus and flexural strength of the composite improved with an increase in the milling time. The density, thickness swelling, and porosity of the composite were also influenced by the milling times. The result suggested that the composite properties were influenced by the particle size of the coconut shell. The coconut shell nanoparticle composite can be used in the manufacturing of hybrid panels and board.

“…Singh et al used micro size coconut shell particles to form a composite with the epoxy. Their report showed that the microparticles enhancement improved the flexural strength and density of the composite [ 15 ]. Somashekhar et al combined coconut shell powder and tamarind shell powder to form a composite by using the epoxy matrix.…”

Composites are materials made out of a polymer resin reinforced by fibers, merging the high mechanical and physical enactment of the fibers and the appearance, bonding and physical properties of polymers. For these uses the exchange of industrial fibers with natural fibers could be considered. Many natural fibers traditionally employed in weaving, sacking and ropes; present various abilities to be used as reinforcement elements in composites. Reinforced polymer composites have started to play a pivotal role in a wide range of applications due to their high strength and modulus. The fibers used may be synthetic or natural in reinforced composites. Due to high production cost, the usage of synthetic fibers is confined whereas natural fibers apart from being cheap in cost, it is also strong, less weight and amply available.

“…Imoisili et al had study the concentration effect of coconut shell ash (CSA) on the tensile properties of polyester composite was investigated. Five filler concentrations (5 to 25 weight %) were fabricated, Results were obtained for each of the tensile strength, elastic modulus, and micro-Hardness of the composite increases with increase in filler concentration, while percentage elongation and load at break decreases with increase in filler concentration [4].…”

The mechanical behavior of coconut shell (CS) particulate epoxy composites was concentrated on keeping in mind the end goal to create designing materials for modern application. Minute of the support with various weight portions (5, 10, 15, 20 and 25) wt%. Epoxy and composite materials were prepared by hand lay-up molding. The physical properties are thermal conductivity while the mechanical properties were hardness, tensile properties, impact properties, and flexural strength. The resulting composites of thermal conductivity 0.1005 W∕ m.c° that is lower than pure epoxy and commonplace materials utilized for home-structures. As for the mechanical properties, composite materials with (Epoxy+25%CS) has the maximum hardness of (76.6) shore D, The ultimate tensile strength of 33.42MPa was obtained from (Epoxy+25%CS), while the elongation at fracture with addition in filler concentration of 1.50 % was obtained from (Epoxy+25%CS) is lower than other composites. The highest impact strength, fracture toughness was 80J∕m 2 , 12.87 MPa.m-1/2 respectively. Flexural strength & shear stress of the composite materials with addition in reinforcement content at 5wt % &10wt% (39, 40.5)Mpa & (1.95,2.03)Mpa respectively while is other composites.
