Abstract

3-ply composite laminates based on glass fibers (E-glass or N-glass chopped strand mats, CSM) and jute (J) fabric as reinforcing agents and amine cured epoxy resin as the matrix material were studied employing differential scanning calorimetry (DSC), teremogravimetric analysis (TGA) and scanning electron microscopy (SEM). Mechanical strength and reinforcing effect were much higher for use of glass CSM than jute fabric as the reinforcing agent in making the composite laminates. For each of the cured epoxy resin and laminates based on glass CSM and jute fabric and for each of the glass-jute hybrid laminates, the DSC thermogram is characterised by an endotherm beginning at nearly 30 degreesC and signifying removal of absorbed moisture and by an exotherm beginning at 250-320 degreesC, signifying thermal decomposition. Examination of the epoxy resin and the relevant 3-ply composite laminates by TGA indicated enhancement of degree of thermal stability for the matrix epoxy resin on reinforcement with glass fibers and lowering in the stability on reinforcement with jute fibers. Analysis by SEM indicated that spread of the matrix (epoxy) resin and its adhesion with the reinforcing fibers were much uniform and improved for use of jute fabric than glass CSM as the reinforcing agent.
