The dispersion of nanoparticles plays a key role in enhancing the mechanical performance polymer nanocomposites. In this work, one hybrid epoxy nanocomposite reinforced by well dispersed, zinc oxide functionalized, multi-wall carbon nanotube (ZnO-MWCNT) and core-shell rubber (CSR) was prepared, which possesses both high modulus fracture toughness while maintaining relatively glass transition temperature (Tg). improved from 0.82 MPa m1/2 for neat to 1.46 ternary nanocomposites is resulted...
The fracture behavior of polyrotaxane (PR)-modified poly(methyl methacrylate) (PMMA) was investigated. PR is a supramolecule with rings threaded onto linear backbone chain, which capped by bulky end groups to prevent the from de-threading. ring structure α-cyclodextrin (CD), and it can be functionalized enhance its affinity hosting polymer matrix. Adding only 1 wt % containing methacrylate functional (mPR) at terminal some polycaprolactone-grafted chains on CD promotes massive crazing,...
Abstract In the construction of tunnels under existing stations, it is necessary to control their settlement. When there a pile foundation in station, cutting has significant impact on settlement station. To determine influence piles subway reasonable pile-cutting time proposed. Based Chengdu Metro Line 9 underpassing 1 hatchery law tunnel station analysed via numerical simulation. Furthermore, deformation and stress characteristics piles, pipe roofs, linings supporting effect are discussed....
The effects of the spraying thickness and position on response aluminum plates under impact loading were studied. tests numerical simulation conducted for penetration process polyurea-coated 2024 with tungsten sphere impacts. results indicate resistance performance is similar at slower velocity (500–1000 m/s), front (or double-side) coating has a smaller advantage. When rises to 1500 m/s, back better energy-absorbing performance. polyurea perform more efficiently increase in because...
Abstract A chopped‐glass fiber/multi‐walled carbon nanotubes (MWCNTs) hierarchical reinforcing structure was used to toughen the core‐face interlayer of sandwich materials. Chopped‐fiber mats modified by MWCNTs‐COOH were inserted at face‐core interface before resin infusion. Sandwich beams prepared vacuum‐assisted transfer molding, containing a Polyvinylchloride (PVC) foam core covered with two glass fiber/epoxy composite face sheets. The mechanical properties characterized using...
Abstract Incorporation of reinforcing nanoparticles, like multi‐walled carbon nanotubes (MWCNTs), in a polymer matrix is an effective way to enhance mechanical properties and expand structural applications engineering polymers such as poly(ether‐ether‐ketone) (PEEK). Good dispersion MWCNTs critical for achieving optimal properties. In this work, simple solution mixing approach was utilized prepare PEEK nanocomposites reinforced with MWCNTs. By direct PEEK/dichloroacetic acid MWCNT/ N...
The interfacial region between nanoparticles and polymer matrix plays a critical role in influencing the mechanical behavior of nanocomposites. In this work, set model systems based on poly(methyl methacrylate) (PMMA) containing poly(alkyl glycidyl ether) brushes grafted 50 nm metal-organic-framework (MOF) were synthesized investigated. By systematically increasing brush length graft density MOF nanoparticles, fracture PMMA/MOF nanocomposite changes from forming only few large crazes to...
Chopped carbon fibers with different dispersion types (colony type and uniform type) area densities were inserted at sandwich beams, consisting of a PVC foam core covered two glass fiber/epoxy composite face sheets. The effects this reinforcement on the interfacial bonding between fiber sheets evaluated. Their mechanical properties measured by three‐point‐bending Charpy impact tests. structures after failure observed scanning electron microscopy. Compared beam without reinforcement, bending...
ABSTRACT Interest in developing high‐performance blends for niche applications has grown significantly efforts to meet ever‐increasing harsh environment demands. In this work, four model poly(aryl‐ether‐ketone)/polybenzimidazole (PAEK/PBI) were chosen study the influence of premixing methods, processing, and matrix polymers, on their mechanical properties. Among poly(ether ether ketone) (PEEK) PBI blends, properties are greatly enhanced by melt premixing. The molding process mainly affects...
Delamination damage is a common failure mode of carbon fiber reinforced polymer (CFRP) laminates, which severely limits their application. This paper proposes novel interlaminar toughening structure based on intrinsic and extrinsic multiscale mechanisms using nanoscale multi-walled nanotubes (MWCNTs) microscale core-shell rubber (CSR). approach significantly enhances the fracture toughness laminates without compromising flexural properties. The interleaves toughened CFRP laminate...
With the increasing proportion of renewable energy, power system inertia decreases, and operation uncertainty rises. It brings concerns about frequency operational reliability. However, impacts performance on reliability parameters generation units have not been fully investigated. This paper studies co-evaluation for systems considering wind turbines. Firstly, a regulation model is established capability Then, cluster equivalent turbines incorporated into architecture thermal units, which...
