Studies on Jute/Glass/Hybrid Composites of Polyurethane Based on Epoxy Resin of 9,9'-bis(4-hydroxy phenyl) Anthrone-10(EBAN) and PEG-200
EBAN-PEG-200-TDI-Jute (EANPT-J), EBAN-PEG-200-TDI-Glass (EANPT-G), and EBAN-PEG-200-TDI-Glass-Jute-Glass (EANPT-GJG) composites have been prepared by hand lay up technique at 80 degrees C under 15.4 MPa pressure for 2 h. EANPT-J, EANPT-G and EANPT-GJG possess 33-52 MPa tensile strength, 19-46 MPa flexural strength, 1.3-3.2 kV/mm electric strength and 3 x 10(11)-5 x 10(11) Ohm cm volume resistivity, respectively. Hydrolytic stability of the composites was tested against water, 10% aq. HCl and NaCl solutions at 35 degrees C and also in boiling water. The percentage of water uptake, equilibrium time, and diffusivity of the composites have been determined and discussed their possible applications. (C) 2010 Wiley Periodicals, Inc.
