Abstract: | Thermal
analysis of jute fibre reinforced vinylester resin with 30 vol% of fibre were
performed by TG/DTG under dynamic conditions. The fibres were treated with
alkaline solution at different temperatures and the final composition (cellulose,
hemicellulose and lignin) of the fibre was determined by chemical analysis.
Apparent activation energies were determined using a variety of conventional
thermogravimetric methods. Two peaks were found in the composite differential
curves: the first peak close to 327 and the second peak at 408°C. The
apparent activation energy values for the second peak decreased when fibre
were treated. The addition of the jute fibres produced a slightly decrease
in the thermal stability of the composites. |
