Evaluation of the Mechanical and Thermal Characteristics of Polypropylene Composites Reinforced with Benzoylation-Processed Banana Fibre and Sisal Fibers

Abstract

Mechanical and thermal properties of composites reinforced with Banana fibre (BF) and Sisal fibre (SF) were investigated in this study. Benzoylation therapy was effective for Banana fibre /Sisal. The hybridised bio-composites (PP/BF/SF) with a total 10 weight percentage were produced using three different fibres ratios between Banana fibre - and Sisal-treated. The thermal stability experiments are performed using thermogravimetric analysis (TGA) and diffraction scanning calorimetry (DSC). According to flammability test results, the treated hybrid composite (BF / PP /SF) burned at the slowest rate (only 28 mm/min) and the stiffness damping factor (Tan δ). The loss modulus (E "the ideal (PP/BF/SF) hybrid composite, T-BF5SF5, has a damping factor of 0.058 and a modulus of 86.2 (MPa). Thermomechanical analysis (TMA) was also used to effectively record the dimensional coefficient (m) versus temperature studies, with T-BF5SF5 achieving the highest dimensional coefficient (m) of 30.11 at 110°C.
