Improving the interfacial shear strength of carbon fibre and epoxy via mechanical interlocking effect

In this study, an effective and environmentally friendly method is proposed to enhance the interfacial shear strength between the carbon fibre and resin by the mechanical interlocking effect. The Fenton chemical reaction was used to oxidize and construct uneven structure on the carbon fibre surface, followed by functionalization with amine (-NH2) groups. The carbon fibre surface morphology was first designed, and the mechanical properties of the...
