“…The first load drop point was attained as the debonding force (Figure 5(f)). Sato et al [61] speculate that when the IFSS of the interface is too high, the interface can not be entirely debonded before matrix failure, which is observed in this study (Figure 5 Through the successful 15 tests from baseline specimens and 14 tests from BNNTs/SiCfs, the force-embedded area plot was examined for IFSS evaluation. IFSS can be determined by simply averaging the calculated data or the linear regression slope of the force-embedded area plot that intercepts origin [57].…”

Aramid fibers form an important group of fibers for composite applications. These applications range through lightweight shell structures, protective structures in ballistic applications such as helmets and various shields, protective clothing, and car tires, for instance. For structural applications, the composites of aramid fibers and high performance resins must form integral and strong parts. Therefore, the fiber-matrix interface places a significant role. Numerous surface treatments and fiber modifications have been applied over the years to adjust aramid fibers. On the way to improve and optimize these interfaces, various test methods have been applied. The recent studies apply microtesting, e.g., in the form of microdroplet tests. Furthermore, the material properties of the resin, fiber, and interface are used to create numerical models. However, the current challenge is to collect statistically reliable data as well as the necessary parameters to validate the simulations on different length scales.

“…Studying the mechanical properties of the interface can reveal the influence of interface structure, properties and stress on mechanical properties, which provides a basis for further understanding the deformation and failure mechanism of composite materials [5]. At present, the commonly used interface testing methods include fiber pull-out [6,7], droplet debonding [8][9][10], fiber breaking [11] and fiber push-out [12][13][14]. Among them, the fiber push-out test, as a method for in-situ test of real materials with a need to prepare special specimens, can conveniently detect the change of interface properties through a load displacement curve.…”

In this study, a fiber push-out device based on a piezoelectric actuator was designed, analyzed and tested, and its experimental environment was designed. The piezoelectric actuator includes a flexible beam. By using response surface analysis (RSM), taking the large displacement as the objective function and on the premise of meeting the strength requirements, the structural parameters of the flexible beam were analyzed. In the process of fiber push-out, the interfacial shear stress was estimated by establishing the system integrating the fiber-matrix-composite three-phase model and the piezoelectric actuator model using the analytic method, and the theoretical analysis results of the fiber interface mechanical properties were given. A prototype of the system was made, and the performance tests of the piezoelectric actuator and the fiber push-out device were carried out. The test results showed that the designed piezoelectric actuator can achieve a stepping resolution of 6.67 μm and a maximum displacement of about 100 μm at the input voltage of 150 V, which is consistent with the design results. The extrusion test of a single fiber was carried out using a piezoelectric actuator. The mechanical properties of the interfacial layer during the push-out process were measured and the interfacial shear strength was calculated, which is consistent with the theoretical analysis results. Finally, based on the mechanical properties obtained from the test, the loading failure process of the fiber was simulated by finite element analysis, which well explained the failure process of the fiber, thus verifying the feasibility of the designed fiber push-out device.
