“…The condition of interfacial debonding during push-out has been defined using two criteria: the shear strength criterion [17][18][19] and the critical energy release rate criterion [20][21][22][23]. In the strength-based approach, which is adopted in this study, it is assumed that interfacial debonding occurs when the maximum interfacial shear stress reaches the interfacial shear strength.…”

“…According to this test method, the inner phase is pushed-out from the outer phase using a hard flat-bottomed punch and a universal testing machine. Parallel to the development of experimental methods and techniques to evaluate the interfacial properties, several numerical analyses have been developed and their applicability has been proven [9,[17][18][19][20][21][22][23][24][25][26].…”

“…The interfacial shear is related to the embedded length leading to the pull‐out phenomenon according to Eqn (2)

τ_{max} = \frac{τ α l_{e}}{tanh (α l_{e})}

with α and the value of the IFSS τ max being two constants that are characteristics of the considered fiber‐matrix interface. α is related to the Young modulus of the fiber E f , the shear modulus of the matrix G i and the thickness of the interphase that transfers the stress from the matrix to the fiber b i according to Eqn (3)

α^{2} = \frac{2 G_{i}}{b_{i} r E_{f}}

Other more advanced models have been published by Lawrence, Chua and Piggott, Zhandarov et al ., Zhandarov and Pisanova and Hsueh . Nevertheless, Désarmot and Favre used several models to fit experimental data and showed that even if the Greszczuk's model was developed with the simplest hypothesis, it was also the one that fitted their data the best.…”

A time-dependent oxidation of carbon fibers in boiling nitric acid was used to investigate the influence of a modification of the fiber surface properties on the adhesion strength with an acrylate resin cured by electron beam (EB). For each time of treatment, a characterization of the surface topography and the surface chemistry was done (topography at a micrometric and nanometric scale, specific surface area, temperature programmed desorption, X-ray photoelectron spectroscopy analysis). The oxidation of the fiber surface in boiling nitric acid created a rough surface, which significantly increased the specific surface area, and also generated a high density of hydroxyl groups, carboxylic acids and lactones in comparison to untreated fibers. The adhesion strength with the acrylate resin cured by EB was measured by a pull-out test. For comparison, an isothermal ultraviolet curing of the matrix was also investigated. The value of the interfacial shear strength, determined by the Greszczuk's model, was increased by the oxidation of the carbon fiber surface for both curing processes, but lower values were systemically obtained with EB curing.

“…During straining the composite material reinforced with textile structures, macro-cracks are formed and propagated through the composites in which the bonding state at the interface is known for transferring the externally applied stresses from the matrix to the reinforcements [27]. As a matter of crack growth resistance, filament bridging and pull-out are major powerful energy dissipation mechanisms in composites materials [28,29]. They are directly correlated to the interfacial bonding between the filaments and the surrounding matrix.…”

In the present study, novel woven reinforced single polymer composites (WSPC) based on polyamide 6 (PA6) is developed via a combination of powder-coating of PA6 textile reinforcements with PA6 empty microcapsules (EMC) and compression molding techniques. Activated anionic ring-opening polymerization of ε-caprolactam was employed to synthesize the PA6-EMC which was transformed during the compression molding into WSPC matrix without damaging the PA6 textile reinforcements. A promising novel class of PA6 woven fabrics, stitched plain, which are patented by Jakob Müller company AG® were used as reinforcements. The tensile properties of stitched plain reinforced WSPC were studied and compared to ones reinforced by the plain-woven structure and the PA6 neat matrix reference materials. The parametric studies are performed on the stress field along the elements of reinforcements, using image processing to correlate the influence of reinforcement architectures with the failure mechanism of WSPC.
