(2) Exceeding the optimal CNF content leads to a decrease in toughness due to fiber aggregation. (3) CNF tends to aggregate more readily on the surfaces of carbon fibers, which limits the improvement in toughness compared to incorporation into the resin. (4) Adding CNF to resin more effectively enhances fiber/resin interfacial adhesion, which contributes to improved interlaminar fracture toughness. References Deutz, D. B., Bosch, A. F., Baptista, D.
