    Study of the interfacial adhesion between alfa fiber and synthetic resin in a new biocomposite material
    (Elsevier, 2022) Kadem, Sihem; Irinislimane, Ratiba; Belhaneche-Bensemra, Naima
    The Interfacial adhesion between fiber and resin has a strong influence on composite mechanical performance and thermal stability. Natural fibers like alfa have attracted a great interest to be used as reinforcement for polymer composites. In this work biocomposites were prepared from natural substances by bleinding alfa plants (Stipa tenacissima) as natural reinforce fibers and modified sunflower oil (Helianthus annuus) as synthetic resin. The application of alfa fibers as reinforcement for composites requires a strong adhesion between the fibre and the resin. In the present work, alfa fibers were added to the synthetic resin after alkaline treatment with 5% NaOH solution. Biocomposites were prepared by using treated and untreated alfa fibers and characterised in terms of tensile properties, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The results showed a good interfacial adhesion between treated alfa fibers and the resin. On the other hand, a thermal improvement was observed for biocomposites with treated alfa fibers

    Effects of corona discharge treatment on the mechanical properties of biocomposites from polylactic acid and Algerian date palm fibres
    (2013) Amirou, Siham; Zerizer, A.; Haddadou, Imane; Merlin, A.
    In this paper, biocomposites materials based on date palm fibres (untreated or treated with corona discharge) as reinforcing elements and polylactic acid matrices were prepared and characterized. The objective of this study was to evaluate the mechanical properties of these biocomposites by modification of date palm fiber by using corona discharge treatment which results in a surface oxidation. The morphology of processed biocomposites was studied by scanning electron microscopy. It was found that treated fibers of the reinforced composite showed superior mechanical properties as compared with untreated fiber reinforced composites due to the enhanced adhesion between the treated date palm fiber and the polylactic acid matrix. Changes in the surface chemistry were investigated with Fourier Transform infrared spectroscopy. Moreover, morphological studies by scanning electron microscopy demonstrated that better adhesion between the treated fiber and the matrix was achieved. Such studies are of great interest in the development of environmentally friendly composites from biodegradable polymers
