“…Luo et al [32] coated PVC on bi-axial warp knitted fabric and demonstrated that the coated fabric exhibited anisotropic properties under both mono-axial and multiaxial tensile loads. Li et al [33][34][35] studied the tension fatigue behavior and failure mechanism of 3D MWK composites, and their tensile and bending properties at cryogenic temperature. Ma et al [36] added short glass fibers between MWK fabric layers to improve interface strength.…”

Interfacial bonding between the fibers and matrix plays a large role in mechanical properties of composites. In this paper, poly(oxypropylene) diamines (D400) and graphene oxide (GO) nanoparticles were grafted on the desized 3D multi axial warp knitted (MWK) glass fiber (GF) fabrics. The surface morphology and functional groups of modified glass fibers were characterized by scanning electron microscopy (SEM) and fourier transform infrared spectra (FT-IR). Out-of-plane compression properties and the failure mechanisms of composites at different temperature were tested and analyzed. The results revealed that GO nanoparticles were successfully grafted on fibers under the synergistic effect of D400. In addition, D400-GO-grafted composite possessed the highest mechanical properties than desized composite and GO-grafted composite. Their strength and modulus were improved by 10.16%, 10.06%, 8.92%, 8.75%, 7.76% and 40.38%, 32.74%, 29.85%, 26.98%, 25.16% compared to those of desized composites at 30∘C, 60∘C, 90∘C, 120∘C, 150∘C, respectively. The damage to D400-GO-grafted composite was yarns fracture accompanied with fibers breakage, matrix cracking, interface debonding. At higher temperature, interlayer slipping with matrix plasticization was the main failure mode.

“…Recently, Yudhanto et al 19,20 studied the effect of stitching on compression properties and damage mechanisms and indicated that stitching generally reduces the compression strength of carbon/epoxy composites. Li et al [21][22][23] presented an experimental study on tensile, bending, dynamic properties, and failure mechanism for 3-D MWK composites at different temperatures and showed the fiber architecture and environment temperature are important factors influencing mechanical properties of composites.…”

This article reports the temperature effects on the in-plane and out-of-plane compression behavior and failure of 3-D multiaxial warp-knitted glass fabric-reinforced epoxy composites. The damage and fracture morphology are observed from macroscopic and microscopic views, and the failure mechanism is demonstrated. The results show that the temperature has significant effect on in-plane and out-of-plane compression properties, the stress versus strain curves decline, and the properties decrease significantly with increasing the temperature. The temperature of 75°C is a key point, at which change in compression properties occurs, and at 150°C, the materials become plastic. Moreover, fiber architecture and loading modes are also important factors on compression properties of composites. The results also show that the damage and failure patterns vary with temperature, fiber architecture, and loading modes. Under in-plane compression, material A shows local 0° fiber layers delaminating and becomes softening and plasticity with increasing temperature. Material B shows delaminating between 0°, 90°, +45°, and −45° fiber layers along 45° angle and exhibits multiple delaminating at elevated temperatures. Under out-of-plane compression, material A shows multiple local shear fracture with 45° angle and experiences softening, roughness, and expansion at elevated temperatures. Material B exhibits shear brittle failure clearly, and delaminating dominates the main failure with increasing the temperature.

“…They provided full data on the bending behavior in the broad range of the radii of curvature. Li et al [22] studied bending properties of composites at cryogenics temperature and found the properties at liquid nitrogen temperature have been improved significantly. The previous studies have shown that the fiber architecture, environment temperature and fiber volume fraction are important factors which can affect the bending properties of composites, and the failure mechanisms of the MWK composites have some correlations with the manufacture processing parameters.…”

This paper reports the effect of temperature on the bending properties and failure mechanism of 3D MWK (Multiaxial warp knitted) composites. Three-point bending experiments on composites with three fiber architectures were performed at four different temperatures. Then the effect of temperature on the load/deflection curves, bending strength and stiffness were analyzed. Macroscopic fracture morphology and SEM micrographs were also examined to understand the deformation and failure mechanism. The results show that the temperature has great impact on the bending properties of 3D MWK composites and the performance decreases significantly with the increase of the temperature. Meanwhile, the bending properties can be affected greatly by the fiber architecture and these decrease significantly with the increase of fiber orientation angle at room and elevated temperatures. Moreover, the damage and failure patterns of composites vary with the test temperature and fiber architecture. At room temperature, the composite exhibits brittle fracture feature and damages in the breakage and tearing of fibers. But at the higher temperature, the composite becomes more softened, cracked and plastic. It damages in fiber layer delaminating, matrix cracking and fiber/matrix interface debonding.
