Özet
In this study, the effects of incorporating electrospun polyvinyl alcohol (PVA) nanofiber interleaves into carbon fiber/epoxy composite structures on low-velocity impact performance were investigated. PVA nanofibers were produced via electrospinning to enhance the mechanical performance of these composites. The properties of the electrospun nanofibers were characterized using scanning electron microscopy (SEM). Carbon fiber/epoxy composite laminates, with and without PVA nanofiber interleaves, were fabricated using the hand-lay-up technique. To evaluate the mechanical performance of the composites, low-velocity impact tests were conducted in accordance with ASTM D7136. The results indicated that the peak reaction force increased by 16.89% for specimens containing a single-PVA nanofiber interleave and by 17.43% for those with double-PVA nanofiber interleaves. The absorbed energy increased by 27.33% for the single-PVA nanofiber interleave specimens, whereas it decreased by 15.80% for the double-PVA nanofiber interleave specimens. The inclusion of a single-PVA nanofiber interleave not only improved mechanical performance but also caused minimal weight increase, making it an ideal solution for aircraft design. Additionally, PVA nanofiber interleaves contributed to lower test result variation, indicating more consistent material behavior.
