Summary: This article studies the resin permeability and mechanical properties of ramie fabric reinforced unsaturated polyester composites. The results show that composites prepared with a fabric with an areal density of 135 g/cm2 have the highest performance in terms of resin permeability, tensile strength, tensile modulus, flexural strength, flexural modulus, and storage modulus. The optimal number of layers is 8, and placing the fabric at 90 degrees to the resin flow direction improves the mechanical properties. Additionally, the composite with 8 layers of the 135 g/cm2 fabric oriented at 45 degrees to the resin flow direction has the highest impact resistance.

Summary: This paper investigates the mechanical behavior and failure mechanism of a novel Al matrix composite reinforced with 3D orthogonal woven carbon fibers. Through numerical and experimental approaches, the quasi-static tensile behavior, local stress response, and progressive failure process are studied. The results show that the calculated stress-strain curve agrees well with the experimental curve, and the composites exhibit apparent periodic and heterogeneous stress distribution. Interface debonding and transverse cracking contribute to the nonlinear response and catastrophic rupture of the composites. Based on the validated model, the influence of fabric structure parameters on the macroscopic properties is further evaluated.

Summary: This study evaluates the deformation of plain woven composite structures induced by the curing process. The effective material property is calculated by considering fabric parameters closely related to the material properties. The theoretical models for predicting the cure behavior and effective material property are incorporated into finite element-based three-dimensional cure simulation. The results revealed the relationship between deformation and composite yarn thickness, as well as the gap between adjacent yarns. The process-induced deformation considering fabric parameters can contribute to improving the manufacturing quality of woven composite structures.

Summary: This paper proposes a novel hybrid process to reduce manufacturing costs and cycles of composite parts in small-batch production by combining incremental sheet forming and autoclave process. The feasibility of the process was verified through experimental and numerical methods for two-point incremental sheet forming of a typical pyramid part using plain fabric prepreg. A metal-fiber-metal (MFM) sandwich panel configuration was used to prevent direct contact between the woven fabric and the forming tool and support die, ensuring the practicability of the ISF process.

Summary: The study investigates the mechanical behaviors and damage evolutions of carbon/epoxy woven fabric composites with different geometries under tensile loading. It is found that the crimp ratio is a critical factor governing mechanical properties, with composites having smaller crimp ratios showing quasi-linear stress-strain curves with higher elastic modulus and strength. The study also reveals that regardless of fabric pattern, the elastic modulus, strength, and damage initiation are linearly correlated with the crimp ratio.

Summary: This paper investigated the off-axis tensile behaviors of triaxial woven fabric reinforced rubber composites, TWFR, experimentally and numerically. Stress-strain curves and tensile failure morphologies were obtained at seven different off-axis angles, showing nonlinear tensile behavior and a tensile-shear mixed failure mechanism in TWFR. The experimental results were in good agreement with the finite element analysis results, indicating the coupling working stage of yarns and rubber matrix in TWFR.

Summary: The study shows that increasing scarf angle reduces the tensile strength of the repaired composite structures, resulting in different types of failure. Finite element analysis using cohesive zone modeling accurately predicts the experimentally observed response, with stress concentration distribution over the bonding area playing a crucial role in determining the failure type. Further investigation reveals that adhesive defects can significantly decrease the strength of the bonded specimens.

Summary: This study used the acoustic emission (AE) technique and wavelet transform to monitor the structural health and evaluate the failure rate of woven fabric composites. The results showed that off-axis samples deformed and curled due to the slippage and rotation of warp and weft yarns. The load-displacement behavior of samples was divided into zones based on frequency and energy criteria. Three failure modes including matrix damage, interface damage, and fiber breakage were identified. High-frequency events above 400 kHz at different angles were attributed to fiber breakage. The angle of applied force effectively influenced the type of fiber failure, with shear failure increasing significantly as the angle between the main directions increased.

Summary: This study conducted mull-scale finite element analyses based on 3D hybrid macro/micro-scale computational models to investigate the in-situ effect imposed by neighboring plies on the failure initiation and propagation of cross-ply laminates. The results showed good agreements between the computational models and analytical predictions, indicating high accuracy in quantifying the in-situ effect. Empirical formulas for in-situ strengths as a function of embedded ply thickness and different ply angle were developed, and new failure criteria accounting for the in-situ strengths were proposed to predict laminated composites failure under multi-axial stress states.

Summary: This study proposes a multi-hit therapeutic nanosystem for tumor treatment using a biodegradable hollow mesoporous Prussian blue (HMPB) nanosystem. The nanosystem encapsulates the heat shock protein 90 (HSP90) inhibitor 17-dimethylamino-ethylamino-17-demethoxydeldanamycin (17-DMAG) and includes thermotropic phase transition material star-PEG-PCL (sPP) and hyaluronic acid (HA) for enhanced tumor cell endocytosis. The nanosystem utilizes photothermal-conversion effect, phase transition, and drug release to inhibit HSP90 activity, block multiple signaling pathways, and induce ferroptosis in tumor cells, leading to potent antitumor effects in vitro and in vivo.

Summary: In this study, a zinc-enriched nanosystem was developed for the treatment of melanoma. The nanosystem demonstrated high photothermal conversion efficacy and was able to regulate glycolysis and provide photothermal therapy. Upon laser irradiation, the nanosystem generated heat energy and released glycolysis regulators, resulting in the inhibition of lactate dehydrogenase and hexokinase II and down-regulation of glycolysis. Additionally, the nanosystem showed potent antitumor efficacy by down-regulating the expression of Akt, p-Akt, HIF-1 alpha, inducing cell cycle arrest, and inhibiting distant metastasis. Overall, this study provides a novel perspective for tumor metabolism and phototherapy to achieve complete tumor regression.

Summary: This study investigates the molecular mechanisms of polyvinylidene fluoride (PVDF) influenced by temperature, electric poling, and mechanical stretching using molecular dynamics simulations. The results show that electric field and uniaxial deformation can induce the transformation from alpha-to beta-phase in PVDF and affect the dipole moment of the system. Mechanical stretching, on the other hand, significantly changes the chain conformations. The study also explores the synergistic effect of electric poling and mechanical stretching and provides molecular-level mechanisms for this effect.

By using multiple materials, interpenetrating phase composites (IPCs) with 3D interconnected structures can be created, offering superior mechanical properties compared to conventional reinforced composites. To accelerate the prediction of IPC mechanical properties, a deep neural operator (DNO) is trained to learn the transient response of IPCs under dynamic loading, providing fast and accurate predictions with a 100X speedup compared to traditional models. This advancement can greatly accelerate IPC structural design and composite material development.
