Perovskite solar cells (PSCs) are multilayer structures. The interface between electron transport layer and perovskite is the mechanical weakest point in flexible PSCs due to its low fracture energy. Herein, we develop a highly adhesive polyamide-amine-based hyperbranched polymers reinforce interface. energy improved from 1.08 2.13 J·m-2 by with groups dynamic hydrogen bond networks. polymer functionalized achieve superior power conversion efficiencies of 25.05% 23.86% for rigid devices,...
The mechanical performance of the fiber tow composite is crucial for textile composites. To characterize tensile properties carbon composite, a test methodology high strain rate loading was developed based on Split Hopkinson bar equipped with an ultra-high-speed camera. composites measured under quasi-static and dynamic rates, respectively. Furthermore, effects gauge length, counts specimens sensitivity are investigated. results indicate that strength related to length specimen affected by...
Abstract Flexible perovskite solar cells (FPSCs) with high stability in moist air are required for their practical applications. However, the poor mechanical under humidity remains a critical challenge flexible devices. Herein, inspired by exceptional wet adhesion of mussels via dopamine groups, we propose multidentate-cross-linking strategy, which combine multibranched structure and adequate anchor sites three-dimensional hyperbranched polymer to directly chelate materials multiple...
Abstract This study investigated the high‐velocity impact behavior of composite plates with different hybrid ratios and structural configurations through experimental numerical simulation studies. The results showed that critical penetration velocity plate generally increases an increase in volume fraction aramid fibers. finite element model developed this accurately simulated laminated fiber various structures. failure patterns were analyzed, it was observed carbon fibers on back face prone...
Abstract Delamination damage is a critical concern for composites—especially aircraft structures—considering their complex service conditions, which include extreme temperatures and impact threats. This study considers the effect of temperature (−20°C to 110°C) on mode‐I interlaminar failure behavior unidirectional carbon/epoxy composite laminates, through series experiments. A simple double compliances method (DCM) without measurement crack length was employed determine mode I fracture...
With the increasing application of composite materials in anti-impact structure, development reliable rate-dependent interlaminar constitutive model becomes necessary. This study aims to assess and evaluate applicability three types cohesive models (logarithmic, exponential power) numerical delamination simulation, through comparison with dynamic test results double cantilever beam (DCB) specimens made from T700/MTM28-1 laminate. Crack propagation length history profiles are extracted...
By using ANSYS Parametric Design Language (APDL), this paper compiled the parametric design macro program for six types of single-layer semi-open spherical reticulated shell structure. structure was realized with given parameters span S, vector high F, radial node cycles number Nx, ring to symmetric regional copies Kn, and upper removed laps Ns. The stress performance compared analyzed. Modelling examples demonstrated that is simple, practical improves efficiency selection analysis under...
