... They found that integrating reinforcements with better flexibility improved energy absorption over pure composite. By including steel-mesh layers alongside numerous layers of off-axis fiber layers, hybrid composites can attain higher levels of initial toughness and sustained load [27,28]. ...
The main limitations of glass fiber composites that control their adoption in various lightweight applications are their inadequate residual strength and damage tolerance. This study emphasizes the fracture toughness and crack resistance of hybrid composites reinforced with different metallic meshes. Hybrid composites were manufactured using an epoxy matrix reinforced with steel and aluminum mesh and glass fiber. Several hybrid arrangements were produced, including pure glass (epoxy and glass fiber), double hybrid structures (steel mesh with glass fiber and Al-mesh with glass fiber), and a triple hybrid (steel, Al-mesh, and glass fiber) with different stacking sequences utilizing the hand-layup method. Tensile fracture properties were investigated through un-notched and double-edge-notch-tension (DENT) tests with two loading orientations (horizontal and vertical). A digital microscope with high resolution was used for examining fracture morphologies. Double and triple hybridization resulted in significant improvements in tensile strength (σt) and strain (εt), with average increases of 16.2% and 15%, respectively. Furthermore, double hybridization retained 45.5% more energy and provided 5.4 % higher stiffness than PG . Double hybridization of Al-mesh significantly improved the fracture characteristics, specifically when positioned horizontally, providing improvements in fracture strength, peak load, KIC and toughness GIC of 19.15%, 55.8%, 35.33% and 88.9%, respectively. Integration of metallic mesh enhanced the damage profile and effectively delayed the propagation of cracks. Decision making technique (TOPSIS) was utilized to select the most effective composite arrangement.
Polymers have extensive applications in various industries. One of them is the application of polymer materials in the textile industry which is an important and profitable industry. Assessment of physical and chemical properties of polymers can serve for analysis purposes of constitutive materials of apparel. This paper presents a mechanical study on the torsional dynamic behavior of textile microfibers i.e., polyester and nylon which are the common materials in the textile industry. As observed in the former investigation, microfibers have different cross-sections. Hence, elliptical and triangular shapes are considered for cross-section of textile microfibers. Nonlocal strain gradient theory in conjunction with Timoshenko-Gere theory is implemented to derive the partial differential governing equations of polyester and nylon microfibers. The accuracy of the utilized methodology is compared with the findings of former investigations. Moreover, two boundary conditions i.e., clamped–clamped and clamped-free are taken into account. At last, the impacts of various remarkable variants including microfibers cross-section geometry parameters, length scale, and nonlocal parameters on the variation of natural torsional frequency are evaluated and demonstrated in a set of tables and diagrams.
