Few-layer and large-size BNNSs with a high yield of 26% are successfully prepared by simple method.
The highly ordered thermoplastic polyurethane elastomer (TPU)/BNNSs composites are successfully prepared by the combination of filler modification and magnetic alignment.
Interface between the carbon fiber and epoxy was vital to mechanical performance of CFRP under cryogenic temperature (−196 °C). In this paper, cryogenic-interfacial-properties fiber/modified (T700/M-Epoxy) −196 °C were analyzed by experiment, theoretical analysis finite simulation method (FEM). Experimental data showed that interfacial shear strength (IFSS) T700/M-Epoxy at 75.8 MPa, which increased 16.1% in comparison with (65.3 MPa) room (RT). For analysis, microbond sample could be...
The widespread use of composite materials has led to an increased focus on restoring the mechanical properties damaged structures ensure system safety. This study combines compression experiments and finite element simulations investigate effectiveness different patch sizes repair methods, including single- double-sided repairs, in structural strength laminates with barely visible impact damage (BVID). results demonstrate that low-velocity significantly affects laminate, reducing it 68.53%...
A three-dimensional foam is fabricated to enhance the interfacial interaction between adjacent MXene sheets and polyimide (PI) macromolecules; then a composite film with dense well-ordered layer-by-layer structure, good flexibility flame retardancy produced.
Abstract L‐shaped stiffened composite panels inevitably produce delamination defects during manufacturing and service, which seriously affect the load‐bearing performance of structure. In present work, a combination experimental numerical simulations was used to investigate effect initial with three different shapes (lossless, elliptical, circular) in skin on axial compression properties carbon fiber panels. Furthermore, predict damage initiation evolution process fiber‐reinforced polymer...
The thermal conductivities of single-layer BC<sub>3</sub> (SLBC) sheets and their responses to environmental temperature, vacancy defects external strain have been studied compared with those C<sub>3</sub>N (SLCN) by molecular dynamics simulations.
As a next-generation thermal management material, the graphene film with outstanding conductivity and superior flexibility shows attractive prospects in many applications. However, its mechanical performance are difficult to further improve because of weak interfacial interactions between sheets large quantity phonon scatterings induced by structural defects. In this work, we fabricate three-dimensional foam via forming cross-links oxide (GO) polyimide (PI), then, graphitized films produced...
In-plane heterojunctions, obtained by seamlessly joining two or more nanoribbon edges of isolated two-dimensional atomic crystals such as graphene and hexagonal boron nitride, are emerging nanomaterials for the development future multifunctional devices. The thermal transport behavior at interface these heterojunctions plays a pivotal role in determining their functional performance. Using molecular dynamics simulations, interfacial conductance graphene/hexagonal nitride (GE/BN) in-plane was...

The approach based on the bionic optimization technology Cuckoo search algorithm. It addresses problem jamming limitation in previous approaches and able nonuniformly dispersed microstructures with high fiber fractions any specified inter-fiber distances. Statistical analysis implemented evaluate nonuniform distributions generated...
Owing to high specific strength and designability, unidirectional carbon fiber reinforced polymer (UD-CFRP) has been utilized in numerous fields replace conventional metal materials. Post machining processes are always required for UD-CFRP achieve dimensional tolerance assembly specifications. Due inhomogeneity anisotropy, differs greatly from materials failure mechanism. To improve the efficiency avoid machining-induced damage, this paper undertook study correlations between cutting...
