Finite Element Analysis of a Natural Fiber (Maize) Composite Beam
(Hindawi Limited 410 Park Avenue, 15th Floor, 287 pmb New York NY 10022, 2013) Saravana Bavan, B.D.; Kumar, G.C.M.
Natural fiber composites are termed as biocomposites or green composites. These fibers are green, biodegradable, and recyclable and have good properties such as low density and low cost when compared to synthetic fibers. The present work is investigated on the finite element analysis of the natural fiber (maize) composite beam, processed by means of hand lay-up method. Composite beam material is composed of stalk-based fiber of maize and unsaturated polyester resin polymer as matrix with methyl ethyl ketone peroxide (MEKP) as a catalyst and Cobalt Octoate as a promoter. The material was modeled and resembled as a structural beam using suitable assumption and analyzed by means of finite element method using ANSYS software for determining the deflection and stress properties. Morphological analysis and X-ray diffraction (XRD) analysis for the fiber were examined by means of scanning electron microscope (SEM) and X-ray diffractometer. From the results, it has been found that the finite element values are acceptable with proper assumptions, and the prepared natural fiber composite beam material can be used for structural engineering applications. © 2013 D.

Reuse of natural plant fibers for composite industrial applications
(Apple Academic Press, 2013) Saravana Bavan, B.D.; Mohan Kumar, G.C.
Natural fibers are considered to be the next generation fibers for the composite manufacturers, because they have the potential to replace the synthetic or the traditional fibers. In the present days composite industries are emerging from small scale to large scale sectors, which include marine, aerospace, automotive, and other military applications. Among them natural plant fibers are widely used especially in automotive and structural applications, packaging industries, and others. Various issues and aspects of natural plant fibers for industrial applications are studied. Reuse and recycle of these plant fibers for the composite technologies are focused. Developments of these natural plant fibers for the industries are highly expected in the market. © 2013 by Apple Academic Press, Inc.
Significant aspects on thermal degradation of hybrid biocomposite material
(2013) Saravana Bavan, B.D.; Mohan Kumar, G.C.
Interest in use of bio fibers is increasing rapidly in structural and automotive applications because of few important properties such as low density, mechanical properties, renewability, biodegradation and sustainability. The present work is focused on fabricating a hybrid bio-composite material processed through compression molding technique. Natural fibers of maize and jute with bio polymeric resin of epoxidized soya bean oil are used as a matrix in obtaining a hybrid bio composite material. Thermal degradation of the prepared material is studied through Thermal gravimetric analyzer. Chemical treatment of the fibers was performed to have a better adhesion between the fibers and the matrix. The work is also surveyed on various parameters influencing the thermal properties and other aspects for a hybrid bio composite material. Â© 2013 AIP Publishing LLC.
Thermal properties of maize fiber reinforced unsaturated polyester resin composites
(2013) Saravana Bavan, B.D.; Mohan, K.G.C.
Increase in demand for natural fiber composites are raising today because of more advantage when compared to traditional fiber composites. In the present work, natural fiber composite material is processed by vacuum assisted resin transfer molding technique and the fibers are maize stalk fibers with matrix of unsaturated polyester resin. With suitable catalyst and accelerator composite material is fabricated and thermal properties for the material is examined by thermal gravimetric analyzer, differential scanning calorimeter and the results are also compared with finite element method.
