This study investigates the optimization of polyphenylene oxide (PPO) electrospinning for interlaminar toughening in composites, using sulfonation modification and physical blending with polylactic acid (PLA) polystyrene (PS). Both strategies showed excellent performance, significantly reducing fiber diameter (PPO: 12.1 ± 5.8 μm; sulfonated PPO: 524 42 nm; PPO-PLA: 4.73 0.94 PPO-PS: 3.43 0.34 μm). In addition, PPO-PS fibers were uniform, while PPO-PLA exhibited a mixture fine coarse due to phase separation. Interlaminar fracture toughness testing that offered greatest toughening, GICini GICpre increasing by 223% 232%, respectively, compared values untoughened sample, 65% 61.5% those PPO sample. GIIC sample was 196% greater than 30% higher Scanning electron microscope (SEM) analysis morphology revealed high-toughness system dissipated energy through bridging, plastic deformation, multi-scale crack deflection, low-toughness samples failed interface debonding or cohesive failure. work demonstrates veils enhance reinforcement multiple mechanisms, providing an effective approach high-performance composites.
