Synthetic fiber reinforced concrete. Normally coir is a commercial product which creates out of coconut husks and coconut coir is a by-product of coconut fruit which can create lots of value-added products. Then trailed the paper used as stationary phase for color separation. This is because WCC have higher flow resistivity than coconut coir fibers, so that sound can be dissipated as it travels through material significantly. All rights reserved. In addition, old newspapers were embedded in the specimen to hold the coir fibres each other. Extracted cellulose by the soda process. pursue the 'possibilities of using coir as a base material for board products. When added to paper it lends a fibrous appearance and texture as well as strengthening the paper. 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. The coir were treated to avoid the degradation factor. In addition, old newspapers were embedded in the specimen to hold the coir fibres each other. There have been relatively few reports on the usage of coir fibers as an alternative raw material for pulp and paper products. It exhibits that properly chosen fibers along with suitable amount of bulk density can increase the absorption for the same layer thickness. McDonald’s set a goal, by 2020, to use certified or recycled sources for 100 percent of its fiber-based packaging (such as hot cups, carry out bags and clamshells). The kenaf fiber was treated with different concentration of alkali treatment, soaking time and temperature. The conclusion suggests that coir fibres can be one of the alternative raw materials which can be applied for packaging product. It was found that the developed analytical method can provide a well consistent agreement with the experimental results. The innovative sound absorption panel was developed and fabricated using treated coir fibre layers as sound absorption materials. In addition to the testing on real world paper-pulp packaging samples, FEM modelling and analysis is carried out using the rib similar to those used in testing.

Then, the prepared samples of fiber composites were tested using ASTM D638 tensile test to determine the tensile strength. The coir fibers were characterized using chemical and morphological analyses, to assess the fiber’s potential for the production of pulp and paper. The results show that the bending wave pattern is strongly influenced by the tensile force. Using coir fibers as insulation could reduce energy consumption from 3 to 9% and reduce environmental stress (Mintorogo et al. Modest levels of fibre beating increased the TS of composites, which is believed to be due to improved interfacial bonding. What is commonly called a coconut, as found in grocery stores, is actually only the single seed of a fruit of the coconut palm tree (Cocos nucifera). With the technological development, industrial noises, which are mainly induced by machines, affects negatively on the day-today life of surrounding people. The optimum condition of the alkali treatment on the tensile strength was investigated using response surface method (RSM). In this work, the composite was fabricated with randomly oriented chopped coir and cotton fiber reinforced with unsaturated polyester resin. The effects of porous layer backing and perforated plate on sound absorption coefficient of sound absorber using coconut coir fiber were studied. For the sound absorption coefficient, the experiment gives the value between 0.70 and 0.80 for the frequency range of 1000 to 1800 Hz while the sound absorption coefficient obtained from simulation gives 0.7 to 0.85 for the frequency range of 500 to 2500 Hz. However, there was no investigation had been carried out about the effect of bamboo fibre treatment towards this blend. 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. Conclusion: Noise absorption coefficient of coconut coir fiber was increased at all frequency when they were backing with Woven Cotton Cloth (WCC). However, the imported virgin long fiber pulp from softwood need to be added to maintain the fiber strength for packaging purposes. Fibers recovered from that pulp are called coir. 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. Specimen testing as well as testing of functional elements of packaging (rib separated from packaging support) is explored. Otherwise, the increment of fibres percentages has caused the mechanical paper properties decreased. The interface bonding from the chemical treatment of the reinforced fibers can be seen as a great factor that affecting the mechanical properties of fiber composite. This facilitates the use of combination of black cotton soil and coir fibers for sustainable development purposes. Relationships between pulp fibre and handsheet properties during recycling were assessed by using thirty-three individual trees of Eucalyptus globulus. Asian Journal of Scientific Research 6 (2), 207-216, 2013.
