Abstract In this work, cesium tungsten oxide/graphitic carbon nitride (Cs0.32WO3@g-C3N4) hybrids were successfully synthesized using a facile solvothermal method. The hybrids were incorporated into PVDF and electrospun into Cs0.32WO3@g-C3N4/PVDF fiber membranes. Water evaporation, desalination, and sewage treatment were studied using the photothermal fiber membranes. The experimental results showed that the highest photothermal conversion could be achieved for a fiber membrane composed of 10 wt%...

Abstract In this study, the electromechanical properties and strain monitoring behavior of graphene-coated glass fiber reinforced epoxy (GGFRE) composites were investigated. Glass fabrics were first coated with 2 wt% graphene dispersions using a blade coating method and composites of these graphene-coated glass fabrics were manufactured using vacuum resin infusion. As-prepared GGFRE showed an increase in normalized resistance (ΔR/R0) by 4.46%, 10.5%, 11.07% and 11.27% proportional to the applied...

Abstract Bistable carbon fiber composites, whose bistability arises from having asymmetric fiber layouts in different layers, have shown immense potential for using in shape morphing and adaptive structure applications. While many studies in this field focus on these composite laminates' external shapes at the two stable states, their snap-through behavior of shifting from one stable shape to the other remains a critical aspect to be investigated in complete detail. Moreover, symmetric loading c...

Abstract Owing to their high thermal conductivities, the direct addition of carbon nanotubes (CNTs) as fillers for ablative insulation materials inevitably has a deleterious effect on the performance of the obtained composites. However, this paper found that CNTs could reduce the thermal conductivity of the char layer skeleton of ethylene propylene diene monomer (EPDM) composites at high temperature. In this study, the ablation characteristics of EPDM composites with CNTs were tested using an ab...

Abstract The continuous development of microelectronics requires mechanically enhanced insulating materials with a lower dielectric (low-k) constant. To accomplish this, in this paper, low-k polymer nanocomposites were reinforced with hydrophobic ethane-bridged mesoporous organosilica (EMO) particles as fillers. In this study, three types of EMOs such as pure EMO, EMO functionalized with trimethoxyphenylsilane (PTS) (EMO-PTS) group, and EMO functionalized with 1-[3-(trimethoxysilyl)propyl]urea (...

Abstract In this study, an energy-based model for predicting the fracture angle of matrix failure in unidirectional carbon-fiber-reinforced polymer (CFRP) under three-dimensional mechanical loading was developed. The elastic stresses in the undamaged area and the frictional stresses in the damaged area were considered in determining the complementary free energy density in the CFRP damage process. The fracture angle of the transverse matrix failure was predicted based on the maximum dissipation ...

Abstract Pore defects that inevitably produce during the manufacturing process, have distinct effects on the mechanical properties of 3D braided composites. A trans-scale method coupled with Micro-CT is developed to investigate the strength and damage behavior of 3D braided composites with pore defects. Pore defects and yarns are measured by Micro-CT and reconstructed. Then, the trans-scale finite element models are established on the Micro-CT data. The progressive damage model and cohesive-zone...

Abstract A scalable manufacturing process has been developed to grow carbon nanotubes (CNTs) in situ on the surface of continuous carbon fibers (CFs) and achieve their uniform distribution. The successful growth of CNTs on the fiber surfaces was proved by studying the various stages in the continuous growth process. Electrochemical anodization achieved significant modification of CFs and promoted effective coating of catalyst precursors. The average tensile strength of the CNTs/CF reinforcement ...

Abstract Composites with barium strontium titanate (BST) or nickel zinc ferrite (NZF) spherical inclusions mixed in a silicone matrix were manufactured at volume fractions ranging from 5% to 25%. The dielectric and magnetic parameters were measured from 1-4 GHz using a coaxial airline. The relative permittivity increased from 2.74±0.01 for the polydimethylsiloxane (PDMS) host material to 7.45±0.33 after combining PDMS with a 25% volume fraction of BST inclusions. The relative permittivities of B...

Abstract Simultaneously improving mechanical strength and toughness of thermosetting polymer nanocomposites remains a great challenge even though massive efforts have been made by controlling the aggregation and interface interaction of nanoparticles. In fact, crosslinking inhomogeneity and crosslinking density of thermosetting polymer nanocomposites can also profoundly affect the competing mechanical properties. Due to their conflicting influence on the toughness and strength of thermosetting p...
