“…The samples of different volume fraction of fibres was tested in an impedance tube. Samples with 80% corn husk fibres volume revealed the highest acoustic performance compared to other samples [137]. Therefore, there is a big opportunity to use straw fibres BCB as a noise suppressant in buildings [138].…”

In recent years, considerable attention have been given to the development and utilization of biodegradable fibres for bio-composite boards. This is due to the increase in the environmental consciousness and the need for sustainable development which enable establishment of new materials majorly for packaging, aircraft, furniture, and automobile. Straw fibres (wheat, rice, and corn fibre) are the most available natural agricultural wastes products, which has been utilized for the production of these new materials. This paper hence reviews the enhancement in production methodology and properties of the straw fibres bio-composite boards to add further scientific knowledge to the potentiality of using agricultural fibres as value added products. The future replacement of conventional wood fibres for the production of bio-composite panels, especially with agricultural wastes, could be centered on straw fibres. The introduction of straw fibres in polymer matrices were presented based on various research outcomes. Biodegradable fibres could be regarded as a good fibrous composite material. Although, more efforts are still needed in developing facile straw fibre composite production methods and materials with robust industrial and domestic applications.

Waru fiber-aluminium laminate composite is engineering materials which have high stiffness, strength properties and weight to strength ratio. The aim of this study is to find out the effect of the number of waru fiber to tensile strength on laminate composite waru fiber-Aluminium. The process of laminating composite waru fiber-aluminium is done by vacuum infusion resin method with layers variation 1, 2, 3, 4 and fiber direction 45/45 angle woven basket. The result shows that the tensile strength of the waru-Al fiber composite decreases and the elongation value of the composite increases due to the addition of layers of fiber waru lower bond strength on adhesive-aluminum and adhesive-waru. The lowest tensile strength of 153,642 MPa has occurred in composite with 4 layers of waru fibre.

“…Tuntutan akan komponen atau material yang ringan dan mampu struktural mengalami peningkatan yang signifikan. Salah satu material yang dapat memenuhi hal tersebut ialah material komposit yang diperkuat serat alam, seperti daun pandan, cornhusk, batang kelapa dan lidah mertua [1][2][3][4]. Murah, mudah diproses, renewable, berlimpah dan tidak membahayakan kesehatan manusia [5,6]; keunggulan ini telah menjadikan serat alam lainnya menarik untuk diselidiki sifatsifatnya.…”

Serat Corypha utan lamarck, yang kaya selulosa, murah, berlimpah memiliki potensi untuk penguatan pada komposit termoset. Penelitian ini bertujuan untuk menyelidiki sifat-sifat dari komposit epoksi berpenguatan serat Corypha utan lamarck. Pembuatan komposit telah dilakukan dengan menggunakan teknik vacuum bagging. Efek penambahan fraksi volume serat Corypha Utan (CU) dengan variasi 20, 25 dan 30 % (fraksi volume) terhadap morpologi, sifat kekuatan tarik dan lentur dari komposit telah diselidiki dan dianalisa. Hasil studi menunjukkan bahwa penambahan fraksi volume serat Corypha Utan secara siknifikan meningkatkan kekuatan tarik dan lentur dari komposit; dikarenakan penyebaran serat merata dalam resin, dan interface yang cukup kuat terbentuk antara serat dan epoksi. Komposit CU/epoksi dengan variasi fraksi volume serat 30% (spesimen komposit CUh) memiliki nilai kekuatan dan modulus tarik sebesar tur paling tinggi sebesar 28.13 MPa dan 39.40 MPa, berturut-turut. Modulus lentur paling tinggi dimiliki oleh komposit dengan fraksi volume serat CU sebesar 30%. Analisa foto SEM memperlihatkan ikatan interface antara serat-epoksi dan fiber breakage. Hasil ini menunjukkkan bahwa komposit Cu/epoksi dapat menjadi alternatif sebagai papan komposit komersil. Corypha Utan fiber, which is rich cellulose, cheap and abundant has the potential for reinforcement in thermoset composites. This study aim is to investigate the properties of epoxy composites reinforced Corypha Utan fibers. The manufacture of composite has been done using vacuum bagging technique. The effect of increasing of the volume fraction of the Corypha utan fibers with variations of 20, 25 dan 30 % (volume fraction) on morphology, the tensile and flexural strength of composites have been investigated and analyzed. The results show that the increase of the volume fraction of Corypha utan fibers significantly increased tensile and flexural of composites; it is due to the dispersion of the fibers in epoxy, and interface bond between fiber and epoxy formed strong enough. The CU/epoxy composite with the volume fraction of the fiber of 30% (Composite CUh specimens) has the highest tensile and flexural strength value of 28,13 MPa and 39,400 MPa, respectively. The moduli’s flexural gives higher value at 30% volume fraction. SEM images demonstrate that interfacial adhesions between fiber-epoxy, and fiber breakage. The result suggests that Corypha utan fibers/epoxy composites can be a good alternative as commercial composites boards, especially for interior applications.
