| 1 | Mechanical Property and Morphological Analysis of Polyester Composites Reinforced with Cyperuspangorei Fibers显示文摘In the present work,polyester composites reinforced with a newly identified Cyperus pangorei fiber(CPF)were developed by compression moulding technique.The effects of varying fiber content and fiber length on the mechanical properties of the Cyperus pangorei fiber reinforced polyester composites(CPFCs)such as tensile,flexural,and impact properties were studied.Mechanical strength of the CPFCs increased with fiber length up to 40 mm beyond which a reverse trend was observed.Based on the test results,it was concluded that the critical fiber length and the optimum fiber weight percentage were 40 mm and 40 wt%respectively.The maximum increase of 164%and 117%were found for the tensile and flexural strength of the composite with 40 mm fiber length and 40 wt%fiber content,respectively.On the other hand,a 64%increase in impact strength was noticed for the optimum case.The increasing contact surface between the fiber and the polyester matrix in optimum condition can restrict the probability of fiber pullout and in turn can make the composite carry more load.The chemical structure of CPF was also analyzed using Fourier-Transform Infrared Spectroscopy(FTIR)spectrum.The morphological analysis of fractured samples was performed using Scanning Electron Microscopy(SEM)to understand the interfacial bonding between CPFs and polyester matrix.The optimal composite can be a suitable alternative in the field of structural applications in construction and automobile industries. | Mayandi Kalimuthu Rajini Nagarajan Alavudeen Azeez Batcha Suchart Siengchin Varada Rajulu Anumakonda Nadir Ayrilmis | 2019 | Journal of Bionic Engineering2019，16，1： | 2 |
| 2 | Characterization of Novel Lignocellulosic Spinifex littoreus Fibers and Their Composites显示文摘This innovative work presents mechanical,physical and chemical characterization and analysis of newly extracted fiber from naturally resourced plant stem,named Spinifex littoreus fibers(SLF).This is a novel natural,biodegradable and sustainable reinforcement for an improved composite.Initially,the chemical constituents of SLF,such as cellulose,lignin,moisture and wax content were studied.The raw SLF surfaces were modified by chemical treatment with sodium hydroxide(NaOH),calcium hydroxide(Ca(OH)2)and silane.A polyester matrix was reinforced with all the treated SLF,before the mechanical properties(tensile strengths)of the composites were determined.Among all the surface chemically treated SLF/polyester composite samples,the Ca(OH)2 treated sample exhibited the highest tensile strength.Further microscopic examination was carried out to validate this result.Also,this analysis established the mechanism of failure of the tensile fractured composite samples,using Scanning Electron Microscope(SEM),among other techniques. | Milan Soosai Christopher Thankian Winowlin Jappes Jebas Thangiah Rajini Nagarajan Mayandi Kalimuthu Sikiru Oluwarotimi Ismail Faruq Mohammad | 2020 | Journal of Bionic Engineering2020，17，2： | 0 |
