Abstract: In this work mercerization, acetylation, and resorcinol/hexamethylenetetra- mine (R/H) solution treatments have been applied to sisal fibers to enhance adhesion with polymer matrices in composite materiais. The thermal behavior of raw and chemi- cally treated sisal fibers has been studied using the thermal gravimetric analysis (TGA) and the differential thermal gravimetry (DTG). The value of the initial decomposition temperature of sisal has been found to increase as a result of mercerization/acetylation treatment. Moreover, the rate ofthermal degradation offibers treated with RIH solution has beenfound to be lower than those of the raw fibers. |
