“…Carbon fibers are more popular than natural fibers in many fields of application due to their mechanical performance and excellent energy absorption capacity [15,16]. However, carbon fibers and their composites are more expensive than most other fibers reinforced polymers.…”

In recent years, the hybridization of natural fibers with synthetic fibers has received much attention. This paper conducted an experimental study on the tensile and flexural behavior of unidirectional carbon/flax fiber reinforced epoxy composites and single flax fibers. Four hybridization rates were considered for 16 reinforced layers in a symmetric staking sequence, with the carbon ply at the surface. The damage evolution under load increase was monitored using the acoustic emission (AE) technique. The Davies–Bouldin index and the K-means clustering algorithm were used to correlate the hybridization rates to the contribution of each damage mechanism to overall failure. AE monitoring of tensile and flexural behaviors showed that delamination and fiber breakage mechanisms dominate the composite failure, regardless of the hybridization rate.

From this reason, single fiber push-out (SFPO) has been widely adopted to continuous SiC fiber-reinforced ceramics composites 8), 9) and C/Cs 6), 10), 11) . On the other hand, author's previous study revealed that SFPO had a limitation in specimen preparation 10), 11) .…”

Fiber-matrix interface mechanical properties are the key design point for the composites, however, methodology for evaluating interface properties of C/Cs are not still well established. In this study, capability of the fiber bundle push-out method was demonstrated as a measurement technique of fiber-matrix interfacial mechanical properties of various C/Cs. First, to carefully determine the experimental conditions to give proper interface mechanical properties, the influences of a radius of an indenter and the thickness of specimens on the measured results were examined. From the experimental result, interface debonding stress, τ d , and sliding stress, τ s , could be obtained as a constant value independent from specimen thickness as long as tested using the same indenter size and the proper specimen thicknesses of < 400 µm. However, absolute value of especially τ d showed dependence of on indenter size. This was shown to be the limitation of this method that τ d obtained from this method cannot be treated as a quantitative value. To demonstrate the capability of the method, the change of fiber-matrix interface mechanical properties of C/Cs on the type of fibers and final heat treatment temperature. τ d decreased with the heat treatment temperature in both C/Cs with pitch based carbon fibers, K633 and K321 and C/Cs reinforced with a carbon fiber with higher heat treatment temperature gave lower τ d at the same heat treatment temperature. Main reason for the degradation of τ d up to 2273K was attributed to the enlargement of debonding area at fiber-matrix interface. Degradation of τ d was enhanced at the temperature range of > 2273 K by the structure change of the interface from the graphitization of matrices. Finally, The fiber bundle push-out method was proved to be a strong tool to investigate fiber-matrix interface mechanical properties of C/Cs.
