Abstract
The investigation on the thermogravimetric analysis of unsaturated polyester matrix composites reinforced with untreated saccharum fibers and other treated by alkaline solution of NaOH with four weight percent include 0.5, 1, 2 and 2.5% was involved in this work. Generally the incorporation of saccharum fibers slightly change the thermal stability of the unsaturated polyester matrix by the weight loss value and only for reinforcement by unsaturated sacchrum fibers and that treated in 2.5% NaOH.
