Analysis of Applicability of the Hollow Carbon Fibres for Self-Repairing Composites

Abstract

The geometry and mechanical properties of solid and hollow carbon fibres were investigated by light-and scanning electron microscopy, and by single fibre tensile tests. The hollowness factor of fibres was determined by their external and internal diameter. The tensile strength was determined by single fibre tensile break tests. It was shown that the bigger the diameter of the fibres the lower the mechanical properties is. It was found that the hollow carbon fibres are suitable for preparation of a self-repairing composite with the advantage over other solutions because of their geometrical and mechanical properties.

Analysis of Inclined Crack in Aluminium Alloy Plate Subjected to Three-Point Bending Load Repaired with Carbon Fiber Reinforced Polymer

“…Cracks are usually formed on the surface of the structure and use of hollow Carbon fibers reduced the probability of crack propagation. These material were called as 'intelligent materials' because of their self-healing property [18]. Sandwich structure of Aluminium alloy honeycomb and carbon fiber/epoxy prepreg system was tested for three-point bending test.…”
