A more comprehensive analysis is necessary to incorporate nanoparticles and the hybridization of different natural and synthetic fiber types, as seen in a composite composed of glass and wool fibers. In this research, polyester/wool-glass fiber with nano-alumina (Al<sub>2</sub>O<sub>3</sub>) particles at 2.0 wt% reinforced polymer composites (C0A-C5A) were made via hand layup and compression molding. The addition of Al<sub>2</sub>O<sub>3</sub> nanoparticles on wool-glass fiber reinforced composites and its effect on properties and morphology were characterized using mechanical testing and scanning electron microscopy (SEM) methods. The analysis of nanoparticle dispersion and the resulting modifications to the composite structure were performed using X-ray diffraction. Adding nano alumina enhanced the tensile strength by 55 %, compressive strength by 38 %, flexural strength by 109 % and impact strength by 47 %. The higher tensile strength of 99.39 MPa, compressive strength of 102.51 MPa, flexural strength of 135.22 MPa and impact strength of 380.34 kJ/m<sup>2</sup> were found in (C1A) glass fiber with nano alumina mixed composites.

Key findings indicate that K content significantly influences workability, strength, and physical properties. Replacing sand with K reduced workability by up to 21 % due to its finer particle size and porosity. The K5 series, containing 5 % K, exhibited the highest compressive strength improvement, with gains of 8.9 % and 16.3 % at 7 and 28 days, respectively, compared to the control. However, higher K contents (10 %, 15 %) negatively impacted mechanical performance. At elevated temperatures, significant mass loss occurred up to 400 °C, after which it stabilized at 600 °C while maintaining structural integrity. Porosity and water absorption increased with K content, except in K5. Microstructural analysis revealed that the K5 series formed a dense, crack-minimal matrix, whereas K10 and K15 exhibited more microcracking and porosity.

The acidic and basic properties of the catalysts were quantitatively assessed through potentiometric titration, confirming the presence of both acid and basic sites, which are essential for the concurrent esterification of free fatty acids (FFAs) and transesterification of triglycerides. This bifunctionality is particularly advantageous for feedstocks with high FFA content, such as waste cooking oil, addressing a key challenge in biodiesel synthesis. The SrO-based catalyst demonstrated exceptional performance, achieving yields of 96 % for corn oil and 93 % for waste cooking oil, with minimal yield differences of 3 % attributed to the latter's impurities and higher FFA content. The study also provides detailed optimization of reaction conditions, revealing that waste cooking oil requires slightly harsher conditions (100 °C, 6 h, 20 mg catalyst) compared to corn oil (80 °C, 5 h, 10 mg catalyst), which is consistent with its complex composition. Comprehensive characterization (PXRD, SEM-EDX, BET/BJH) and validation through <sup>1</sup>H NMR spectroscopy (yields of 92 % and 91 % for corn and waste cooking oil, respectively) confirm the reliability of the results.

Nine different layups of hybrid composites, varying in the number of glass/epoxy plies, were analysed under three-point bending conditions. The study considers two predominant failure modes: microbuckling and delamination. Results show that delamination is the most likely failure mode, particularly at higher interlaminar shear stresses, while microbuckling is less critical in comparison. The predicted flexural strengths, based on delamination criteria, align closely with experimental data, with relative differences less than 2 %, demonstrating the significant influence of stacking sequence on hybrid composite performance.
