  • effect of surface microfibrillation of sisal Fibre on the mechanical properties of sisal aramid Fibre hybrid composites
    Composites Part A-applied Science and Manufacturing, 2011
    Co-Authors: Lin Xin Zhong, Shi Yu Fu, Xue Song Zhou, Huai Yu Zhan
    Abstract:

    Surface microfibrillation of Cellulose Fibre was adopted as a facile method for improving Cellulose Fibre/phenolic resin interfacial adhesion in hybrid composites composed of sisal Fibre and aramid Fibre. Development of microfibrils and aggregates on the Fibre surface significantly increased the interfacial adhesion between the sisal Fibre and resin by providing a large contact area and by inhibiting the formation of spontaneous cracks in the composites. Consequently, the compression, tensile and internal bonding strengths, and wear resistance of the hybrid composites were remarkably improved. Surface microfibrillation of sisal Fibre to a DM value of 24 °SR increased the tensile strength, internal bonding strength and wear resistance values of composites by 93%, 124% and 31%, respectively.

  • laccase and alkali treatments of Cellulose Fibre surface lignin and its influences on Fibre surface properties and interfacial behaviour of sisal Fibre phenolic resin composites
    Composites Part A-applied Science and Manufacturing, 2010
    Co-Authors: Xinwen Peng, Lin Xin Zhong, Junli Ren, Runcang Sun
    Abstract:

    This paper is an attempt to investigate the influences of enzyme (laccase) and alkali treatments on the surface lignin of single Cellulose Fibre. The Fibre surface characteristics and the interfacial behaviour of the sisal Fibre/phenolic resin composites were also studied by SEM, AFM, XPS. The surface lignin greatly affected the surface physical and chemical properties of single Cellulose Fibres. The surface lignin concentration was up to 35% for the raw Fibre without any treatment, and then it decreased to 24%, 20% and 18% for the Fibres with laccase treatment, alkali treatment and laccase/alkali treatment, respectively. The removal of lignin from Fibre surface could enhance the interfacial strength of composites, and thus increase the tensile strength and internal bonding strength by 43% and 51%, respectively, for the composites obtained from laccase/alkali treated Fibres.

  • effect of water absorption on the mechanical properties of nanoclay filled recycled Cellulose Fibre reinforced epoxy hybrid nanocomposites
    Composites Part A-applied Science and Manufacturing, 2012
    Co-Authors: Hatem R Alamri, I M Low
    Abstract:

    Recycled Cellulose Fibre (RCF) reinforced epoxy/clay nanocomposites were successfully synthesized with different weight percentages (0%, 1%, 3% and 5%) of organoclay platelets (30B). The objective of this study was to investigate the effect of water absorption on the physical and mechanical properties of the RCF reinforced epoxy/clay nanocomposites. TEM images indicated a well-intercalated structure of nanoclay/epoxy matrix with some exfoliated regions. Water absorption was found to decrease as the clay content increased. The flexural strength, flexural modulus and fracture toughness significantly decreased as a result of water absorption. However, the properties of impact strength and impact toughness were found to increase after exposing to water. The addition of nanoclay slightly minimized the effect of moisture on the mechanical properties. SEM images showed that water absorption severely damaged the Cellulose Fibres and the bonding at Fibres–matrix interfaces in wet composites.

  • mechanical properties and water absorption behaviour of recycled Cellulose Fibre reinforced epoxy composites
    Polymer Testing, 2012
    Co-Authors: Hatem R Alamri, I M Low
    Abstract:

    Abstract Recycled Cellulose Fibre (RCF) reinforced epoxy composites were fabricated with Fibre loadings of 19, 28, 40 and 46 wt%. Results showed that flexural strength, flexural modulus, fracture toughness and impact strength increased as the Fibre content increased. The ultimate mechanical properties were achieved with a Fibre content of 46 wt%. The effect of water absorption on mechanical and physical properties of RCF/epoxy composites was investigated. The values of maximum water uptake and diffusion coefficient were found to increase with an increase in Fibre content. Flexural strength, modulus and fracture toughness decreased as a result of moisture absorption. However, the impact strength was found to increase slightly after water absorption. XRD, FTIR and SEM studies were carried out to evaluate the composition and microstructure of RCF and RCF/epoxy composites.

  • fabrication and properties of recycled Cellulose Fibre reinforced epoxy composites
    Composite Interfaces, 2009
    Co-Authors: I M Low, J Somers, H S Kho, Ian Davies, B A Latella
    Abstract:

    Epoxy matrix composites reinforced with recycled Cellulose Fibre (RCF) were fabricated and characterized with respect to their flexural and impact properties. Reinforcement of the epoxy by RCF resulted in a significant increase in the strain at failure, fracture toughness and impact toughness but only a moderate increase in flexural strength and flexural modulus. The effect of accelerated exposure to seawater on the flexural and impact properties was also investigated. The salient toughening mechanisms and crack-tip failure processes were identified and discussed in light of observed microstructures, in particular the orientation of RCF sheets to the applied load.

  • mechanical and fracture properties of Cellulose Fibre reinforced epoxy laminates
    Composites Part A-applied Science and Manufacturing, 2007
    Co-Authors: I M Low, B A Latella, M Mcgrath, D Lawrence, P Schmidt, J Lane, K S Sim
    Abstract:

    Abstract Epoxy laminates reinforced with Cellulose-Fibre mats (CFM) have been synthesized and characterized. The influence of CFM dispersion on the mechanical and fracture properties of these laminates have been characterized in terms of elastic modulus, hardness, flexural strength, fracture toughness, indentation responses, impact-fracture, crack-growth resistance and in situ fracture. The reinforcement by the CFM resulted in a significant increase in the strain at break, indentation creep, fracture toughness and impact toughness but moderate increase in flexural strength and flexural modulus. A pronounced R-curve behaviour is exhibited by the CFM-reinforced epoxy sample, which failed in a graceful manner with slow and stable crack-growth. The micromechanisms of toughening and crack-tip failure processes are identified and discussed in the light of observed microstructures from in situ and ex situ fracture. The implications for new approaches in the ‘eco-design’ of environmentally friendly composite materials are addressed.
