摘要

Among the tested specimens, the composite PAN1, reinforced with 3 vol% nanosilica, exhibited superior interlaminar shear strength (26.1 MPa), tensile strength (117 MPa), flexural strength (124 MPa), and impact strength (3.27 J). These enhancements are attributed to the efficient and uniform dispersion of nanosilica throughout the composite, which improves load transfer and overall mechanical performance. Alternatively, the PAN2 composite containing 5 vol% nanosilica demonstrated the highest shore-D hardness (99) and fatigue life counts of 14,895 at 75% UTS, 17,235 at 25% UTS, and 15,794 at 50% UTS, owing to the filler’s effective load transmission, surface hardness enhancement, and crack resistance. Overall, the 3 vol.%nanosilica-reinforced composite exhibits a combination of superior mechanical properties. Based on these results, it is suggested as a potential repair material for applications where environmental conditions or physical damage compromise structural integrity, such as wind turbine blades or automotive components.
