  • thermo mechanical properties of epoxidized hemp oil based Bioresins and biocomposites
    Journal of Reinforced Plastics and Composites, 2013
    Co-Authors: Nathan W Manthey, Gaston Francucci, F Cardona, Thiru Aravinthan

    Abstract:

    Novel epoxidized hemp oil-based biocomposites containing jute fibre reinforcement were produced at the Centre of Excellence in Engineered Fibre Composites (CEEFC) owing to the need to develop new types of biobased materials. Mechanical properties (tensile, flexural, Charpy impact and interlaminar shear), thermo-mechanical properties (glass transition temperature, storage modulus and crosslink density) and moisture-absorption properties (saturation moisture level and diffusion coefficient) were investigated and compared with samples containing commercially produced epoxidized soybean oil and a synthetic bisphenol A diglycidyl ether-based epoxy control, R246TX cured with a blend of triethylenetetramine and isophorone diamine. Scanning electron microscopy was also performed to investigate the fibre-matrix interface. Epoxidized hemp oil-based samples were found to have marginally superior mechanical, dynamic mechanical and similar water-absorption properties in comparison to samples made with epoxidized soybean oil bioresin; however, both sample types were limited to bioresin concentrations below 30%. Synthetic epoxy-based samples exhibited the highest mechanical, dynamic mechanical and lowest water-absorption properties of all investigated samples. This study has also determined that epoxidized hemp oil-based Bioresins when applied to jute fibre-reinforced biocomposites can compete with commercially produced epoxidized soybean oil in biocomposite applications.

  • Thermo-mechanical properties of acrylated epoxidized hemp oil based biocomposites
    Journal of Composite Materials, 2013
    Co-Authors: Nathan W Manthey, Gaston Francucci, Francisco Cardona, Thiru Aravinthan

    Abstract:

    In this study, novel acrylated epoxidized hemp oil bioresin was used in the manufacturing of jute fibre reinforced biocomposites. The 100% biocomposite laminates were characterised in terms of mechanical properties (tensile, flexural, Charpy impact and interlaminar shear), thermo-mechanical properties (glass transition temperature, storage modulus and crosslink density) and water absorption properties (saturation moisture level and diffusion coefficient). Comparisons with the equivalent synthetic vinylester resin based jute fibre reinforced biocomposite panels were performed. Scanning electron microscopic analysis confirmed panel samples containing acrylated epoxidized hemp oil to display improved fibre–matrix interfacial adhesion compared with the vinylester resin based samples. Furthermore in terms of mechanical properties acrylated epoxidized hemp oil based biocomposites compared favourably with those manufactured from vinylester resin synthetic resin. Dynamic mechanical analysis found acrylated epoxid…

  • Curing kinetics of bio-based epoxy resin-toughened DGEBA epoxy resin blend
    Journal of Thermal Analysis and Calorimetry, 2019
    Co-Authors: Sudheer Kumar, Sapan Kumar Samal, Smita Mohanty

    Abstract:

    In the present study, TEIA bioresin was blended with the diglycidyl ether bisphenol A (DGEBA) epoxy resin in different ratios (i.e. 10, 20, 30, 40 mass%), cured with methylhexahydrophthalic anhydride curing agent in the presence of 2-methylimidazole catalyst. The optimized composition of DGEBA and TEIA bioresin blends system was employed as an adhesive strength. The adhesive strength of the TEIA-modified DGEBA epoxy resin blend system was increased from 4.14 to 6.31 MPa on an aluminium substrate compared to the DGEBA epoxy resin. The curing kinetics of non-isothermal, DGEBA epoxy resin and its bio-based blend systems were investigated employing differential scanning calorimetry. An increase in the peak temperature and reduction in a heat of curing as well as activation energy in DGEBA epoxy resin were observed with the addition of TEIA bioresin content. The activation energy ( E _a) of the DGEBA resin and their bio-based blend system were obtained from Kissinger and Flynn–Wall–Ozawa methods.

  • Epoxidized Soybean Oil-Based Epoxy Blend Cured with Anhydride-Based Cross-Linker: Thermal and Mechanical Characterization
    Industrial & Engineering Chemistry Research, 2017
    Co-Authors: Sudheer Kumar, Smita Mohanty, Sushanta K. Samal, Sanjay K. Nayak

    Abstract:

    The present research is based on a comparative study of anhydride cured biobased and petroleum-based epoxy network. The effect of epoxidized soybean oil (ESO) bioresin on petroleum-based epoxy (DGEBA) at varying compositions cured with methylhexahydrophthalic anhydride (MHHPA) as curing agent and 2-methyl imidazole (2-MI) as the catalyst has been investigated. The tensile strength of virgin epoxy (42.94 MPa) increased to 48.62 MPa with the addition of 20% of ESO. The fracture toughness parameters; critical stress intensity factor (KIC) and critical strain energy release rate revealed enhancement of toughness in the biobased blends. Differential scanning calorimetry studies confirmed an enhancement in the peak temperature and a reduction in the heat of curing in virgin epoxy on incorporation of ESO content. The thermomechanical and fracture morphological properties of virgin epoxy, ESO, and its biobased blends were investigated by thermogravimetric analysis, dynamic mechanical analysis, atomic force micros…

  • Study of thermal stability and thermo-mechanical behavior of functionalized soybean oil modified toughened epoxy/organo clay nanocomposite
    Progress in Organic Coatings, 2015
    Co-Authors: Sushanta K. Sahoo, Smita Mohanty, Sanjay K. Nayak

    Abstract:

    Abstract In the current study, nano-clay was incorporated in toughened epoxy modified with epoxidized soybean oil (ESO) to improve the mechanical and thermal properties. Curing behavior was studied by Fourier Transform Infrared spectroscopy and Differential Scanning Calorimetry analysis to investigate the effect of ESO bioresin and nanoclay on cross-linking reaction. The increase in enthalpy of curing reaction and decrease in peak temperature of nanocomposite corroborated the catalytic effect of clay on the curing process. The thermal stability parameters like integral procedural decomposition temperature and decomposed activation energy were determined using Horowitz and Metzger equation. Dynamic mechanical analysis demonstrated the high storage modulus, improved crosslink density and good damping behavior of nanocomposite. Thermo mechanical analyzer was used to examine the coefficient of thermal expansion (CTE) of bio-based epoxy blend and nanocomposite in both glassy and rubbery region. The CTE value is decreased after addition of clay to the modified epoxy blend which confirmed the improved dimensional stability of the nanocomposite. TEM and X-ray diffraction analysis confirmed both intercalated and exfoliated clay platelet within the epoxy blend.
