Recyclable 3D printing of thermosets was realized by utilizing the solvent-assisted recycling covalent adaptable networks (CANs). The printouts, if damaged or after usage, were fully depolymerized in an organic solvent, and they partially cured into a new ink for next round printing. This work presents fundamental studies to understand influences composition rheological properties on printability, recyclability, thermomechanical printed CAN components. A polyimine-based is used as material...
Continuous fiber-reinforced polymer composites, with their superior combinations of high stiffness, strength, lightweight, and corrosion resistance, have been leading contenders in various applications ranging from aerospace to ground transportation. The integration 3D printing allows the composite products be customized quickly fabricated inexpensively meet unique specifications. However, material-process-property relationships printed thermoset composites continuous fiber are...
ABSTRACT Surface welding effect of covalent adaptable network (CAN) polymers enables self‐healing, reprocessing and recycling thermosets, but little is known about their behaviors during repeated welding‐peeling cycles. In this article, we study the cyclic an epoxy based thermal‐sensitive CAN. roughness generated by rubbing sample on sandpapers with different grid sizes. The cycles are same pair samples for five times, amplitude interfacial fracture energy measured in each cycle. It shown...
Anisotropic polymers with aligned macromolecule chains exhibit directional strengthening of mechanical and physical properties.
Abstract In order to improve the susceptibility of ultrasonic transducers damage and mismatch in acoustic impedance with test specimens, an impedance-matching layer is introduced between transducer specimen. The impact matching on propagation was analyzed through field simulation. performance improved experimentally evaluated by using a dedicated echo testing system for transducers. optimized considering different materials. results show that non-metallic materials, only (organic silicone...
A simple, one-step electrodeposition process was rapidly performed on a metal substrate to fabricate calcium superhydrophobic surfaces in an electrolyte containing chloride (CaCl2), myristic acid (CH3(CH2)12COOH), and ethanol, which can avoid the intricate post-processing of surface treatment. The morphology chemical compositions fabricated were systematically examined by means SEM, XRD, FTIR, respectively. results indicate that deposited mainly composed myristate, dramatically lower free...
To describe the viscoplastic behavior of materials under cyclic loading, a dislocation density-based constitutive model is developed based on unified theory in which both creep and plastic strain are integrated into an inelastic tensor. The stress evolution during deformation caused by mutual competition interaction between hardening recovery. incorporate physical mechanisms deformation, change mobile density associated with stain proposed model. immobile induced hardening, dynamic recovery,...
Abstract The uniaxial ratcheting behavior of face-centered cubic 6061 aluminum alloy is investigated theoretically based on the crystal plasticity theory. In this model, a simplified flow rule adopted for convenient engineering application, and classical Kocks-Mecking-Estrin isotropic hardening related to dislocation density describe cyclic characteristic material. Armstrong-Frederic kinematic modified associated with cumulative slip predict more accurately. single version model expanded...
One mode phase-field crystal model is introduced to describe morphological transition in the presence of a cubic term. The application field leads comprehensive pattern formation with stripe, triangular and liquid phases. Combining amplitude model, some steady solution amplitudes wave number are easily obtained. convergence between growth morphology size domain investigated. results indicate that parameter term important crystalline phase, especially 2D phase diagrams it can obtain different...
Abstract A new hydrosoluble macromolecular dispersant and modifier, poly(ethylene glycol)-maleic anhydride-acrylic acid (PEG-MA-AA) terpolymer was synthesized via ring-opening reaction free radical polymerization. The chemical structure of the PEG-MA-AA confirmed by Fourier transform infrared (FTIR) spectra nuclear magnetic resonance spectroscopy (NMR), its average molecular weight determined gel permeation chromatography (GPC). Modified sericite (MSE) from (SE) surface modification with...
