✦ Synopsis
Fiber surface treatment is crucial to the properties of fiber composites. The same mechanism applies to hybrid fiber composites. In this work, a two-step surface treatment was conducted on unidirectional and three-dimensional (3D) braided carbon/Kevlar hybrid fibers, and mechanical properties of the resulting composites were evaluated. Hybrid effect of the composites with varying fiber-matrix interfacial bonding was assessed. It was found that the hybrid composites showed significant improvements in flexural strength and interfacial adhesion strength (IAS) after two-step surface treatment, suggesting this process was efficient. Furthermore, the two-step surface treated carbon/Kevlar hybrid fibers-reinforced composite showed a positive hybrid effect on flexural strength, indicating the existence of hybrid effect is related to the nature of fiber-matrix interface.
