coconut fibres, i.e., fibre treated with water (23.54 N/mm 2) followed by fibres treated with chemicals (21.39 N/mm 2 ) . [4] S. Harisha, D. Peter Michael, A. Bensely and D. Mohan Lal, “Mechanical Property Evaluation Of Natural Fiber Coir Composite”, Materials Characterization, Vol. The need for strength or break load, stretch, dimensions or fatigue life will be of influence on the right fibre choice. Mechanical Properties of Coconut Carbon Fibre/Epoxy Composite Material - written by Vijayprakash, Uthrakumar, K. Ramadurai published on 2019/12/18 download full … A coconut fibre content of 1% produced the best combination of flexural, tensile and compressive properties. Gaps in the scientific information on the structure and properties of coir fibre have been identified. By adding the coconut fibre the workability was not achieved which was required. The aim of this study is to determine the influence of coconut coir fiber on the compressive and flexural strength of paving blocks. The coconut fibres treated with gum and pozzolanic materials improved the mechanical properties of coconut fibre reinforced self-compacting concrete (CFRSCC) specimens to a greater extent. Mechanical Properties Coconut Coir Fibre Density (g/cm3) 1.2 Elongation at break (%) 30 Tensile strength (MPa) 175 Young modulus (GPa) 4-6 Water absorption (%) 130-180 The usage of polyester resin as a matrix was chosen because it is the standard economic resin commonly used, preferred material in industry and besides, it yields highly rigid products with a low heat resistance property. With addition of this coconut fibers and ash component, there seems to be an optimistic increase in base strength properties of the mix and also a sound result when it comes … M-30 coconut fiber concrete showed fall in its properties when exposed to temperatures above 200C. The chemical softening recipe was optimized using Box-Behnken design of experiments as 40 % Na2S, 10 % NaOH and 6 % Na2CO3, which notably reduced the fineness (33 %) and flexural rigidity (74 %) and improved tensile property of coconut fibre. Abitha VK, Rane AV (2015) Studies in mechanical, thermal and morphological analusis of EPDM/PolyPropylene coconut pith composites. The fiber obtained from the dry outer covering of the coconut fiber is termed as “coir”. Each fibre material has its own distinctive properties. Compared to coir fiber, coconut trunk particles also naturally contain a high content of lignin and hemicellulose (). Chemically treated coir fibre reinforced specimens yielded better mechanical properties compared to the raw ones. Coconut fibres were subjected to chemical treatment to obtain softer and finer fibres, suitable to blend with other finer fibre like jute. These coir fibres have the tendency to be used as reinforcement in low cost concrete structures particularly in earthquake regions because of their property of toughness and sturdiness. This fiber has the best toughness among all natural fibres. This crack controlling property of fibre reinforcement delays the initiation of flexural and shears cracking. 39, March 2014, pp. Hence coconut fibre can be a better alternative as construction materials. Hence it was concluded that the treatment of coconut fibre had shown improved strength characteristics of CFRSCC specimens. The integrity of concrete is usually questioned due to the fact that after these fire outbreaks the strength of the concrete is reduced considerably. In the present work the mechanical properties namely tensile and flexural properties are evaluated by preparing composites using coconut coir fiber and coconut shell powder by mixing with polymer. Traditionally coconut coir fiber is only used for brooms, mats, ropes and tools of other household. The addition of coconut fibres improved the flexural strength of concrete by about 12%, they also formed good bonding in the concrete. [12] Kaur, M. and M. Kaur (2012). Also other issues like weight, costs and lifespan can influence the choice. Coconut fibre is one of many fibres which can be used in concrete. 10, 2011, pp. Mixing coconut shell powder with epoxy resin enhances its properties and creates a wide range of applications. Fire outbreaks in buildings have been a major concern in the world today. Moroccan J Chem 3(2):3–2 Google Scholar. This study focused on the use of coconut fibre to achieve this feat. 60, 2009, pp. Alkali treatments (NaOH) Alkali treatments caused maximum weight loss (9.3 ± 1.5%) and also changed the colour of the fibres from pale yellowish brown to dark brown. Coconut coir fiber was used as an additive material to improve the strength properties of soils such as the maximum dry density, the cohesion, angle of internal friction and the California bearing ratio CBR. The choice for the right fibre is depending on the characteristics of the application.

Various methods have been adopted to improve the fire resistance property of concrete. Tamarind shell is also a non-food part which is an agro waste. Keywords: coconut shell, aggregate, coconut fiber, mechanical properties, bond properties.

Coconut shell powder exhibits admirable properties compared to other materials such as low cost, renewable, high specific strength to weight ratio, low density less abrasion to machine and environmental friendly. Wettability Properties of Coconut Fiber on Resin Imran Musanif1, Artian Sirun2, Silvy D. Boedi3 1, 2, 3Manado State Polytechnic, Department of Mechanical, Jln. Also it is capable of taking strain, four times more, than other fibres.

"Comparison between Mixtures of Asphalt with Palm Oil Shells and Coconut Shells as Additives." However, the addition of fibres adversely affected the compressive strength. 2074– 2079. Wettability Properties of Coconut Fiber on Resin @inproceedings{Musanif2018WettabilityPO, title={Wettability Properties of Coconut Fiber on Resin}, author={Imran S Musanif and Artian Sirun and Silvy D. Boedi}, year={2018} } For coconut fibre, micro structural analysis (scanning electron microscopy) test was conducted in the laboratory to get a better understanding of the bonding behaviour of fibres. [11] Al-Mansob, R. A., A. Ismail, M. A. Algorafi, M. H. Hafezi and M. S. Baghini (2013). In addition to this mix, sea water replaced the conventional one in the mix and the structural characteristics were ascertained. It showed reduction in strengths in compression when exposed to high temperatures.
