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

摘要

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°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 × 10~(11)_(-5) × 10~(11) Ohm cm volume resistivity, respectively. Hydrolytic stability of the composites was tested against water, 10% aq. HCl and NaCl solutions at 35°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.
