“…Biocomposites materials are produced from a matrix mixed with natural additives such as banana, coconut shell, jute, hazelnut, walnut, kenaf, and apricot seed shell 4 . In recent years, different kinds of eco‐friendly biocomposites using natural bio‐fillers such as banana, 6 jute, 7 cotton, 8 sisal, 9 and coconut shell 10–13 have been produced. In addition, it has been proven that these eco‐friendly biodegradable biocomposites have good mechanical, electrical, acoustic insulating, and physical properties 14,3 .…”

“…Therefore, CSP proved as a candidate to obtain novel biocomposites that have better properties compared with non‐degradable fillers 19,20 . It was figured out that increasing the amount of CSP in the different kinds of matrix systems such as polyester, 21,22 polylactic acid, 23 polyethylene, 24 and epoxy resin 23,25,11 increases Young's modulus, tensile modulus, and tensile strength of biocomposites compared with neat matrices. However, the chemical structure of CSP includes the lignin (29.4%), pentosans (27.7%), cellulose (26.6%), hemicellulose (21%), solvent extractives (4.2%), uronic anhydrides (3.5%), and ash (0.6%) 26 .…”

A new bio‐based epoxy resin (BER) is produced by the esterification reaction between sebacic acid (SAc) as bio‐based acid and epichlorohydrin (ECH). The epoxy resin (ER) is modified with the BER. The biocomposites are prepared using untreated coconut shell powder (CSP), modified coconut shell powder (MCSP), and MER. The CSP and MCSP particles are mixed with MER in varied compositions (10–50 wt%) for preparation of the MER/CSP and MER/MCSP biocomposites. The influences of CSP and MCSP bio‐fillers amounts on the physical properties (density, elastic constants, acoustic impedance, ultrasonic micro‐hardness, and attenuation coefficient) of biocomposites are investigated using the ultrasonic pulse‐echo overlap method (PEOM). It was seen that the densities, both ultrasonic longitudinal and shear waves' velocity values of obtained biocomposites were higher than those of the MER. All elastic moduli of the MER/MCSP biocomposites have higher values than of the neat MER and MER/CSP biocomposites.

“…The highest value of the flexural strength of the composite nano board from this study is 68.83 MPa, where the composition of the composite was 85 vol.% of coconut shell particle and 15 vol.% of epoxy. Somashekhar et al studied the coconut shell composite, but the composition was 30 wt.% of coconut shell particle and 70 wt.% of epoxy [ 16 ]. Their report showed that the flexural strength of their composite was 40 Mpa, which is lower than the result.…”

“…Somashekhar et al combined coconut shell powder and tamarind shell powder to form a composite by using the epoxy matrix. It was found that the tamarin shell powder improved the mechanical properties of the composite [ 16 ]. Durowaye et al also combined coconut shell powder (40 mesh) with palm fiber to form a composite by using the epoxy resin matrix.…”

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.

Os estudos de novas propriedades materiais, a sustentabilidade e o resíduo com input processual são temáticas em evidência na agenda do design industrial. Nesse contexto, o artigo objetiva apresentar o Material Driven Design, método que aborda os materiais seguindo o processo de transformação, tendo como ponto de partida uma determinada matéria prima e sua exploração mecânica, estética e simbólica; objetivando a interação do usuário com as propriedades materiais. O artigo abordará os experimentos com o pó do endocarpo do coco, resíduo sólido em abundância no país. O processo empírico proposto pelo método foi a base para confirmar a hipótese da possibilidade de reaproveitamento e ressignificação residual. Pondera-se o caráter contínuo da pesquisa, e a obtenção de resultados positivos no momento estimulam a continuação exploratória com o intuito de consolidar as propriedades potenciais do material desenvolvido.
