In this work, the fracture mechanism of winding carbon-fiber-reinforced plastics (CFRPs) based on epoxy matrices reinforced by polysulfone film was investigated. Two types polymer were used: oligomer (EO) cured iso-methyltetrahydrophthalic anhydride (iso-MTHPA), and EO-modified (PSU) with active diluent furfuryl glycidyl ether (FGE) iso-MTHPA. At stage, reinforcing placed in middle layer CFRP. The toughness GIR obtained CFRP determined double-cantilever beam delamination method....
ABSTRACT New monomer difurfurylamine easily obtainable from furfural (inexpensive biorenewable feedstock) was used for the synthesis of polyurethane preform. The latest cross‐linked with different amount BMI (bismaleimide) via Diels–Alder reaction, and polymers a high low degree cross‐linking were obtained characterized. self‐healing efficiency investigated differential scanning calorimetry, electronic microscopy, X‐ray tomography, tensile strength measurement end up to 95% restoration...
Abstract Nanocolloidal gels are emerging as a promising class of materials with applications inks in 2D and 3D printing. Polymer nanoparticles (NPs) offer many advantages potential building blocks nanocolloidal gels, due to the ability control NP dimensions, charge, surface chemistry, functionality; however, their printing yet be explored. Here, functional hydrogels formed by percolating oppositely charged latex NPs different dimensions charge densities reported. The shear‐thinning...
An epoxy resin modified with polysulfone (PSU) and active diluent furfuryl glycidyl ether (FGE) was studied. Triethanolaminotitanate (TEAT) iso-methyltetrahydrophthalic anhydride (iso-MTHPA) were used as curing agents. It is shown that during the of initially homogeneous mixtures, heterogeneous structures are formed. The type these depends on concentration hardener. physico-mechanical properties hybrid matrices determined by structure maximum resistance to a growing crack provided...
The work is aimed at studying the impact resistance of epoxy oligomer matrices (EO) modified with polysulfone (PSU) or polyethersulfone (PES) and glass fibers reinforced plastics (GFRP) based on them under low-velocity conditions. concentration dependences strength fracture energy GFRP were determined. It has been determined that type curves depends modifying polymer. shown σ EM thermoplastic-modified change little in range from 0 to 15 wt.%. However, even introduction 20 wt.% PSU into EO,...
A biocompatible metal–organic framework MIL-100(Fe) loaded with the active compounds of tea tree essential oil was used to produce composite films based on κ-carrageenan and hydroxypropyl methylcellulose uniform distribution particles this filler. The featured great UV-blocking properties, good water vapor permeability, modest antibacterial activity against both Gram-negative Gram-positive bacteria. use frameworks as containers hydrophobic molecules natural makes composites made from...
Chemical conjugation or blending with poly(ethylene glycols) (PEGs) are established procedures to facilitate solubilisation of hydrophobic compounds. The techniques bioPEGylation and PEG were applied poly(3‐hydroxybutyrate). In this paper we have examined the properties copolymer poly(3‐hydroxybutyrate‐co‐poly(ethylene glycol)) (PHB‐PEG) composite material polyhydroxybutyrate glycol) (PHB + PEG) compared homopolymer poly(3‐hydroxybutyrate) (PHB). It was found that has significally different...
The authors have proposed the novel approach for evaluation of self-healing effect in carbon fiber reinforced plastics (CFRP) on micro- and macro samples, using dynamic mechanical analysis (DMA) double-cantilever beam delamination methods, respectively. A modified epoxy resin with a was used as matrix plastics. flexural modulus E’ microsamples specific energy (crack resistance) GIR macrosamples given initial crack were chosen criteria evaluating sensitivity parameters to applied is shown....
Local drug delivery systems are an effective approach in the treatment of purulent–septic inflammation bone tissue. Chemically bonded multiphase ceramics based on calcium-deficient carbonate-substituted hydroxyapatite combine resorbability, osteoconductivity, and possibility volumetric incorporation antibiotics. Macroporosity is regulated by concentration polyethylene glycol granules introduced into initial powder composition, followed their extraction. The selected conditions for...
Abstract Prepolymer synthesized from toluene-2,4-diisocyanate (TDI) (hard segment), and polypropylene glycol (PPG-2000) (soft segment) was end-capped with difurfurylamine groups. A new cross-linked self-healing polyurethane obtained via Diels-Alder reaction of the en-capped prepolymer N,N’-bismaleimido-4,4’-diphenylmethane (BMI). Thermal reversibility (DA-reaction) between terminal furanic rings bismaleimide cross-linking agent designed to be responsible for self-healing. Polymers were...
Abstract The possibility of carbon fiber and the polymer matrix interfacial interface improvement by modification surface with functionalized nanotubes. Nanotubes were deposited to aerosol spray deposition, increase tensile strength composite structures. relationship between structure epoxy uniformity nanotube coating was investigated.
This paper is devoted to hydrostatic compression testing of glass microspheres and spheroplastics (syntactic foam) based on them. Despite a significant share the void, for example, with volume fraction in syntactic foam 0.5, void will be equal 0.447. The opposition this material surprising.The authors consider that whole point here determine signs criteria destruction these materials. That why tests were conducted strength set modeling composition an aqueous emulsion.
