Abstract The demand for sustainable, high-performance materials has led to increased interest in bio-based composites. However, optimizing the mechanical properties of such engineering applications remains a challenge. This study addresses this gap by developing and characterizing an epoxy-based biocomposite reinforced with sugarcane bagasse particles, focusing on influence cyclic thermal treatment its properties. particles were chemically treated 1 M NaOH remove impurities, improve interfacial bonding epoxy matrix, enhance overall composite performance. j pulverized 470 µm incorporated into matrix (0–20 wt%) using hand layup method. composites divided untreated thermally groups, latter subjected (100 °C 3 h over 7 days). Mechanical, wear, water absorption evaluated, while fractured surface morphologies analyzed SEM. Results revealed that significantly enhanced composites’ performance, 15 wt% heat-treated showing optimal properties: density 1.102 g/cm , flexural strength 29.13 MPa, ultimate tensile 103.50 impact 3.49 kJ/m 2 hardness 64.70 HS, wear indices 0.034 mg. These findings demonstrate alkali synergistically performance bio-composites, making them suitable diverse applications, including automotive, aerospace, other fields.

This study explores the influence of corncob and borax reinforcements on mechanical flame-retardant properties polyester composites. Composites were produced using hand lay-up technique with varying weight percentages treated-corncob (3, 9, 15 wt%) (12, 15, 18 wt%). Mechanical such as tensile flexural properties, hardness, impact resistance evaluated, alongside flame retardancy through burning rate tests. Morphological elemental analyses conducted Scanning Electron Microscopy (SEM) Energy Dispersive X-ray (EDX), while Fourier Transform Infrared Spectroscopy (FTIR) Diffraction (XRD) provided insights into chemical structure crystalline phases. The XRD analysis indicated an increase in crystallinity index treated corncob, suggesting enhanced order within cellulose structure, which correlates improved properties. FTIR results confirmed presence functional groups indicative cellulose, effective interaction between fillers matrix. findings revealed that adding significantly flexural, modulus, composite containing wt% exhibiting optimal performance. However, strength decreased slightly compared to pure due stress concentrations. In tests, higher content notably reduced rates, demonstrating superior resistance. conclusion, hybrid reinforcement offers a sustainable solution, enhancing resistance, making these composites suitable for applications requiring both durability fire safety.
