    A detailed study on hybrid plant fibers for packaging applications
    (2012) Saravana Bavan, D.; Mohan Kumar, G.C.
    Natural fibers are the most economic and usable fibers in upcoming generation of composite industries. They are valid in several applications of automotive sectors, structural field, and packaging industries. The present work is focussed on processing a hybrid plant fiber of vetiver and maize that can be used for packaging industries. The hybrid fiber is processed through Vacuum Assisted Resin Transfer Molding (VARTM) method. The obtained fiber is a biocomposite material of plant fiber and bio resin of epoxodized soya bean oil. The material is tested for mechanical, thermal and morphology properties and it can be summarized that these novel hybrid fibers are good looking and have appreciable properties that can be used for packaging applications. These materials are green and less harm to environment compared to synthetic fibers.

    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. © 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.

    Investigation on Hybrid Polyester Composite Comprising of Sisal and Coir as a Reinforcement and Fly Ash as Filler
    (Springer Science and Business Media Deutschland GmbH, 2021) Darshan, M.L.; Biradar, S.; Ravishankar, K.S.
    The use of lignocellulosic fibers such as coir and sisal as reinforcements in thermoplastic and thermosetting resins for developing new material having property superior than the existing one. These biofibers have several advantages, such as good strength, flexibility, low densities, low cost, and biodegradability; over synthetic fibers, these natural fibers are made hydrophobic by 8% NaOH treatment. Alkali treatment increases wettability of fibers with resin and interfacial bond strength. This paper is highlighting about the preparation of hybrid composite and testing the prepared samples for various mechanical and tribological tests such as tensile, flexural, and slurry erosion tests conducted for coir/sisal-hybrid fibers with fly ash as a filler in unsaturated polyester resin. The obtained results are further justified by the SEM images of tested samples from different mechanical tests. This material has been used for automobile application and packing material, roofing material in construction technology. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
