“…The fibers are randomly distributed in the square matrix and the cohesive element was inserted on the fiber boundary to simulate the interface mechanical behavior. By periodic boundary conditions and transverse tensile load, the transverse tensile strength of composites could be obtained [35,36], as shown in figure 7.…”

To illustrate the effect of interface and matrix on the transverse mechanical properties of unidirectional carbon fiber reinforced polymer (UD-CFRP) composites, a calculation method for the transverse tensile strength of UD-CFRP considering the interface cracking process was proposed. The effect of interface crack on the composite stress field was considered based on the representative volume element model with a crack interface, and the crack propagation behavior of interface was simulated by the Benzeggagh-Kenane criterion. The transverse tensile strength of unidirectional T300/BSL914C composites was studied using the theoretical method and finite element (FE) model with random fiber distribution. The theoretical results agreed well with the FE results and the relationships between composite strength, interface strength and matrix strength were provided by the theoretical method. The results show that the interface could be divided into three types according to the strength ratio of interface and matrix, including weakest interface, weak interface, and strong interface. When the interface belongs to the weakest or strong interface, the transverse tensile strength is unaffected by the interface strength and it increases linearly with the increase of matrix strength. When the interface belongs to the weak interface, the transverse tensile strength increases linearly with the increase of interface strength and it is unaffected by matrix strength.

“…45 Although it is possible to assess the elastic modulus using these formulas, the limitation is that it does not consider interactions between adjacent inclusions and performs as a function of constituent parameters like volume percentage and modulus. 46 As a result, new theoretical models are required to more correctly predict nanocomposites behavior while accounting for the effect of interphase thickness.…”

In this study, the Ji-developed model for modeling the young modulus of nanocomposites was suggested to predict interphase thickness (Y) and modulus (Ei). The resulting model was evaluated for accuracy by comparing it to the experimental young moduli of various samples. Additionally, the effects of using a compatibilizer or modified nanocellulose on the interphase thickness and modulus of nanocellulose composites are investigated. Those samples exhibiting the highest Y and Ei parameters are TPS/NFC, PA6/NCC, and PVA/NCC, which can form hydrogen bonds with nanocellulose hydroxyl groups due to their ability to form hydrogen bonds. When compatibilizers are applied to nanocomposites or modified nanocellulose is applied in the polymer matrix, interphase parameters increase. In PLA/NFC composites, MA coupling agents were used to increase Y by 4000%, while Ei increased by 1045%. Moreover, the Y and Ei of CNCs modified with aminopropyl triethoxysilane (APS) in polyamide-6/NCC increased from 0.35 to 0.69 (97.14%) and 35.26 to 58.7 (66.47%). The Ji model was also investigated with and without considering the interphase thickness. As a result, the model became better fitted to experimental young modulus results by considering the interphase parameter in nanocomposites.

In this study, the influence of fiber particle size on the mechanical properties of a wood-–plastic composite (WPC) was investigated using a combination of experimental measurements and numerical modeling. Four different sizes of wood fibers (10–20 mesh, 20–40 mesh, 40–80 mesh, and 80–120 mesh) were used to reinforce high-density polyethylene (HDPE), either separately or in combination. The different sizes of fibers produced varying properties in the resulting composites. The smallest fiber size (80–120 mesh) resulted in the lowest flexural and tensile properties, but the highest impact strength (15.79 kJ/m2) compared to the other three sizes (12.18–14.29 kJ/m2). Using a blend of fiber sizes resulted in improved mechanical properties. Composites containing a mix of 20–40 mesh and 40–80 mesh fibers exhibited the best flexural (strength 74.16 MPa, modulus 5.35 GPa) and tensile performance (strength 48.27 MPa, modulus 4.30 GPa), while composites containing a mix of all four fiber sizes had the highest impact-resistant strength (16.08 kJ/m2). Several models, including the Rule of Mixtures (ROM), the Inverse Rule of Mixtures (IROM), and the Hirsch models, were used to predict the performance of WPCs. The ROM model was found to be the most accurate in describing the mechanical properties of WPCs reinforced with multi-size wood fibers, based on the sum squared error (SSE) analysis.
