The different layering sequences of kenaf-banana-jute fiber were hybridized in a vinyl ester matrix by using the compression molding method. The thermogravimetric analysis (TGA), thermomechanical analysis (TMA), dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC) characteristics of the hybrid composites were investigated. Also, pure composites were investigated for comparison purposes. The results from the TGA test revealed that the pure kenaf composites and K-B-J-J-B-K hybrid composites showed better thermal stability. Further, the pure jute composites and K-B-J-J-B-K hybrid composites exhibited the highest coefficient of thermal expansion value of 327 and 391 ppm/°C, respectively. From the DMA analysis, K-B-J-J-B-K hybrid composites possess the highest loss modulus and storage modulus. However, pure kenaf composites and B-J-K-K-J-B hybrid composites had the highest tan delta values. The J-K-B-K-B-J hybrid composites and pure kenaf composites displayed the maximum glass transition temperature (Tg) value observed from the DSC analysis. Certain hybrid and pure composites have improved thermal characteristics, proving that they are appropriate for structural applications in automobiles.
