One of the methods to do that is provided by sound absorber. The responses of this research are tensile index and tear factor. Research and development efforts are continuing to focus on the use of coir in geotextiles and other new applications as the market shows promising prospects. For instance, Mohamad Jani and Rushdan (2014) have successfully produced bleached paper from coir fibers using a chemi-mechanical pulping process. environment. The results show that as beating time increased, the mechanical properties of papers increased. 2 Full PDFs related to this paper. The analysis of variance was conducted using the full quadratic term at the beginning of response surface methodology analysis work. It describes how the physical elements of coir fiber absorber panel can change the absorption behavior. The conclusion suggests that coir fibres can be one of the alternative raw materials which can be applied for packaging product. After they had been extracted, the coir fibers were dried at 70°C to 80°C. It can be used in different applications in the field of automobile, building and construction, consumer products and … (2014). Noise control and its principles play an important role in creating a pleasing, This study was carried out to investigate the characteristics of pulp and paper produced from oil palm oil male flower spikes (OPMFS). On the other hand, sample A produced the highest tear factor, with the value of 92.7 g/mm2. TS and YM were found to decrease for hygrothermal ageing due to fibre damage and reduced fibre matrix interfacial bonding, whilst FS and IS were found to increase due to the plasticizing effect of water. This can be achieved when the intensity of sound is brought down to a level that is not harmful to human ears. Coir (/ ˈ k ɔɪər /), or coconut fibre, is a natural fibre extracted from the outer husk of coconut and used in products such as floor mats, doormats, brushes and mattresses. Wall tiles were made by using saw dust. This is because WCC have higher flow resistivity than coconut coir fibers, so that sound can be dissipated as it travels through material significantly. The coconut tree (Cocos nucifera) is a member of the family Arecaceae (palm family) and the only living species of the genus Cocos. The values of this experimental tensile strength can be used for light weight constructional applications, auto industry, and many custom products. The bending waves are influenced by mechanical properties such as density, thickness, bending stiffness, anisotropy and also by tensile forces in the paper. Perforated plate used was machined with perforation ratio of 0.20, thickness of 1 mm and holed diameter of 2 mm. All rights reserved. This paper has the potential to be developed to use as a substitute material in Bio manufacturing. The sample continues with 10% decreasing content of water and 10% increment of coconut coir. Because of the widespread use of paper throughout the world, it causes the use of wood in large quantities that involves cutting down trees which can lead to negative impacts on ecosystems. Chemical analysis was performed according to Technical Association of the Pulp and Paper Industry (TAPPI) Base on tensile test and tear test results, graphs were plotted and it shows sample D, with 60% of water and 40% of coconut coir has produced the highest tensile strength, breaking length and tensile index, with the value of 1020.6 N/m, 422.8 m and 4.1450 Nm/g respectively. In addition, an example is presented in order to show the approaches of enhancing the absorption utilizing the advantage of modification in the physical elements. The results show that the bending wave pattern is strongly influenced by the tensile force. Noise Reduction Co-efficient (NRC) of these tiles was investigated by using an experimental setup including signal generator, speakers and noise level meter. The effects of porous layer backing and perforated plate on sound absorption coefficient of sound absorber using coconut coir fiber were studied. Natural fiber reinforced concrete. A higher watering of the coconut fibre, as well as an acclimated biomass, allowed an EC of 33.3 g [NH3] m(-3) h(-1) at a 100% RE. This paper discusses the mechanisms of improvement in strength, shrinkage, swelling and compressibility behavior of black cotton soils due to the inclusion of coir fibers. 2015). This includes the determination of tensile and compressive strength of paper-pulp packaging and also to find out whether this material exhibits high variation in the earlier properties. MH Othman, NM Main, SZ Kunchi Mon, Z Mohamad. The fiber dimensions, derived values, and paper properties of coir fiber by the soda-AQ pulping process were recently reported by Nor Mazlana et al. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. The appropriate condition of mobile phase in chromatographic technique (ethyl-methyl ketone, acetone and water) to separate standard colors was also studied. We can press the material into many different shapes. Mohd Hilmi Othman. Both of these brands are known for their quality across their entire product range. Early work on coir fibre Coir is a hard, versatile, natural fibre available in large quantities (World: 0.78 million tons/year; India: 0.16 million tons/year) and is a renewable resource. This process consists of immersing the coir fibers into 5% sodium Hydroxide (NaOH) solution for 24 hours to remove the first layer. With the technological development, industrial noises, which are mainly induced by machines, affects negatively on the day-today life of surrounding people.
