Abstract: Fibreglass composites are widely used in small marine vessels due to their high strength-to-weight and stiffness-to-weight ratios. This study investigates the mechanical behavior of fibreglass composites modified with aluminium phosphate (AlPO4), a combination with limited prior data, especially for marine hull applications. Using ANSYS-based finite element analysis (FEA), three-layer and seven-layer composite models were simulated and validated against experimental results. Composites with 5 wt.% AlPO4 showed peak tensile and flexural strength in both configurations. The three-layer models exhibited simulation errors below 10%, while tensile results of the seven-layer models also aligned closely. Flexural results for the seven-layer systems showed slightly higher deviations, but within 25%. These findings demonstrate the effectiveness of ANSYS in predicting the mechanical performance of AlPO4-enhanced fibreglass composites for marine use. [ABSTRACT FROM AUTHOR]
