Abstract:

This study investigates the physicomechanical, thermal, and structural behavior of polypropylene random copolymer (PPR) a new material reinforced with bamboo particles (BP) for potential use in PPR pipe formulations. Bamboo particles were incorporated at 2.5, 5, 7.5, and 10 wt.% after thermal drying and alkaline treatment using a 20 wt.% NaOH solution to improve compatibility with the polymer matrix. Mechanical testing, melt flow rate (MFR) and density measurements, differential scanning calorimetry (DSC), Fourier-transform infrared spectroscopy (FTIR), and optical microscopy (OM) were conducted to evaluate the influence of particles addition and treatment. Treated particles significantly improved tensile strength and modulus while also affecting other characteristics, such as increasing viscosity (lower MFR) and decreasing the degree of crystallinity. FTIR and DSC confirmed chemical and thermal modifications following treatment, and OM revealed improved fiber dispersion. Overall, the incorporation of 10 wt.% treated bamboo particles led to a marked improvement in the mechanical performance of PPR, with increases of approximately 56.3% in tensile modulus, 24.3% in tensile strength, and 16.2% in elongation at break compared to virgin PPR, highlighting an effective reinforcement while preserving ductility.
