“…It was also reported that an increasing oxygen content after a surface treatment led to the improvement of interfacial shear strength. Furthermore, fracture toughness was improved by hydrogen and covalent bonding interaction [24]. Surface functionalization results in an increase in the polar component as well as the total surface free energy of the fibres.…”

Abstract:Braided textile-reinforced composites have become increasingly attractive as protection materials for various applications, including sports.,In such applications it is crucial to maintain both strong adhesion at fibre-matrix interface and high interfacial fracture toughness, which influence mechanical performance of composites as well as their energy-absorption capacity. Surface treatment of reinforcing fibres has been widely used to achieve satisfactory fibre-matrix adhesion. However, most studies till date focused on the overall composite performance rather than on the interface properties of a single fibre/epoxy system. In this study, carbon fibres were treated by mixed acids for different durations, and resulting adhesion strength at the interface between them and epoxy resin as well as their tensile strength were measured in a microbond and microtensile tests, respectively. The interfacial fracture toughness was also analysed. The results show that after an optimum 15-30 min surface treatment, both interfacial shear strength and fracture toughness of the interface were improved alongside with an increased tensile strength of single fibre. However, a prolonged surface treatment resulted in a reduction of both fibre tensile strength and fracture toughness of the interface due to induced surface damage.

“…The adhesion strength of the interface depends on the thermodynamic work of adhesion that is closely related to the surface energy of the fiber and matrix [85]. Surface energy of fibers has been determined quantitatively by measurement of the contact angles by using Wilhelmy plate technique [86][87][88][89][90]. An excellent comprehensive summary of both the theoretical and experimental aspects of contact angles has been published recently [91].…”
