  • Effect of superheated steam treatment on the mechanical properties and dimensional stability of PALF/PLA biocomposite
    Polymers, 2019
    Co-Authors: Ahmed Jaafar Hussein Challabi, Buong Woei Chieng, Nor Azowa Ibrahim, Hidayah Ariffin, Norhazlin Zainuddin

    Abstract:

    The effectiveness of superheated steam (SHS) as an alternative, eco-friendly treatment method to modify the surface of pineapple leaf fiber (PALF) for biocomposite applications was investigated. The aim of this treatment was to improve the interfacial adhesion between the fiber and the polymer. The treatment was carried out in an SHS oven for different temperatures (190–230 °C) and times (30–120 min). Biocomposites fabricated from SHS-treated PALFs and polylactic acid (PLA) at a weight ratio of 30:70 were prepared via melt-blending techniques. The mechanical properties, dimensional stability, scanning electron microscopy (SEM), and X-ray diffraction (XRD) for the Biocomposites were evaluated. Results showed that treatment at temperature of 220 °C for 60 min gave the optimum tensile properties compared to other treatment temperatures. The tensile, flexural, and impact properties as well as the dimensional stability of the Biocomposites were enhanced by the presence of SHS-treated PALF. The SEM analysis showed improvement in the interfacial adhesion between PLA and SHS-treated PALF. XRD analysis showed an increase in the crystallinity with the addition of SHS-PALF. The results suggest that SHS can be used as an environmentally friendly treatment method for the modification of PALF in biocomposite production.

  • The influence of green surface modification of oil palm mesocarp fiber by superheated steam on the mechanical properties and dimensional stability of oil palm mesocarp fiber/poly(butylene succinate) biocomposite
    International Journal of Molecular Sciences, 2014
    Co-Authors: Yoon Yee Then, Nor Azowa Ibrahim, Norhazlin Zainuddin, Hidayah Ariffin, Wan Md Zin Wan Yunus, Buong Woei Chieng

    Abstract:

    In this paper, superheated steam (SHS) was used as cost effective and green processing technique to modify oil palm mesocarp fiber (OPMF) for biocomposite applications. The purpose of this modification was to promote the adhesion between fiber and thermoplastic. The modification was carried out in a SHS oven at various temperature (200-230 °C) and time (30-120 min) under normal atmospheric pressure. The Biocomposites from SHS-treated OPMFs and poly(butylene succinate) (PBS) at a weight ratio of 70:30 were prepared by melt blending technique. The mechanical properties and dimensional stability of the Biocomposites were evaluated. This study showed that the SHS treatment increased the roughness of the fiber surface due to the removal of surface impurities and hemicellulose. The tensile, flexural and impact properties, as well as dimensional stability of the Biocomposites were markedly enhanced by the presence of SHS-treated OPMF. Scanning electron microscopy analysis showed improvement of interfacial adhesion between PBS and SHS-treated OPMF. This work demonstrated that SHS could be used as an eco-friendly and sustainable processing method for modification of OPMF in biocomposite fabrication. © 2014 by the authors; licensee MDPI, Basel, Switzerland.

  • a jatropha biomass as renewable materials for Biocomposites and its applications
    Renewable & Sustainable Energy Reviews, 2013
    Co-Authors: H Abdul P S Khalil, N. A. Sri Aprilia, A H Bhat, Mohammad Jawaid, Md Tahir Paridah, David Rudi

    Abstract:

    This review deals with the study of Jatropha biomass as renewable materials for Biocomposites and its applications. Jatropha curcas is a multipurpose plant with many attributes and considerable potential. Jatropha plant is cultivated worldwide but it has specific cultivation area in Central and South America, Africa, and South Asia. The Jatropha plant produces many useful products, especially the seed from which oil can be extracted. Extracted oil has similar properties to palm oil and possible to obtain many products after processing. As biomass, Jatropha plant can used as a reinforcement in biocomposite development. Jatropha contain high amount of carbon especially in seed/husk, fruit shell and seed cake and can be used as filler in composite fabrication in the form of carbon black and activated carbon.

In this review, we will discuss the distribution of Jatropha around the globe, chemical composition of various parts and extracts of Jatropha and their mechanical and physical properties. We will also cover the use of Jatropha biomass in various technical and biocomposite applications. With the development of green technology, Jatropha latex can be reduced to nanoparticle size. The chemical and physical properties of Jatropha contribute to its applications in food and non-food Products. © 2013 Elsevier Ltd. All rights reserved.

  • oil palm mesocarp fiber as new lignocellulosic material for fabrication of polymer fiber Biocomposites
    International Journal of Polymer Science, 2013
    Co-Authors: Yoon Yee Then, Nor Azowa Ibrahim, Norhazlin Zainuddin, Hidayah Ariffin, Wan Md Zin Wan Yunus

    Abstract:

    New Biocomposites consisting of poly (butylene succinate) (PBS) and various content (0–70 wt%) of oil palm mesocarp fiber (OPMF) or oil palm empty fruit bunch fiber (OPEFBF) were fabricated by melt blending and subsequently hotpress moulding. The tensile, flexural, and impact properties of those Biocomposites were evaluated and compared. Enhancement of flexural modulus of 200 or 150% was observed with PBS biocomposite loaded with 70 wt% of OPMF or OPEFBF. PBS/OPMF Biocomposites exhibited higher values of tensile, flexural and impact strengths, and tensile and flexural moduli than those of PBS/OPEFBF Biocomposites. These results indicated that OPMF feature better reinforcing agent for PBS as compared to that of OPEFBF.
