Abstract
This work aims to study thermal properties of natural intralaminar hybrid composites with epoxy and polyester matrices. Two different types of natural hybrid composites were produced via hand layup technique (jute + curauá and jute + sisal) with a twill weaved mat of jute and the other fibers as reinforcement. The composites were thermally characterized by thermogravimetric (TGA) and derivative thermogravimetric (DTG) techniques to investigate the thermal stability of the material, comparing the two types of resin used in the research. A scanning electron microscopy (SEM) analysis was used to investigate the morphology of natural fibers in the composites. Hybrid composites showed higher thermal stability for epoxy and polyester resin, showing that the hybridization effect was positive for thermal stability.
