Résumé :

The gyroid structure is a bio-inspired structure that was discovered in butterfly wings. The geometric design of the gyroid structure in butterfly wings offers a unique combination of strength and flexibility. This study investigated sandwich panels consisting of a 3D-printed gyroid structure core and carbon fiber-reinforced polymer (CFRP) facing skin. A filament fused fabrication 3D printer machine was used to print the gyroid cores with three different relative densities, namely 10%, 15%, and 20%. Polylactic acid (PLA) was used as the printing material for the gyroid. The gyroid structure wa

Résumé :

Sandwich panels are composites which consist of two thin laminate outer skins and lightweight (e.g., honeycomb) thick core structure. Owing to the core structure, such composites are distinguished by stiffness. Despite the thickness of the core, sandwich composites are light and have a relatively high flexural strength. These composites have a spatial structure, which affects good thermal insulator properties. Sandwich panels are used in aeronautics, road vehicles, ships, and civil engineering. The mechanical properties of these composites are directly dependent on the properties of sandwich c

Résumé :

Abstract In this study, the performance of A-reinforced sandwich structures made with polymethacrylimide (PMI) foam material is explored. The research focuses on comparing two forming methods, bonding and co-curing. It also tests the static properties of sandwich test pieces under different forming pressures. It reveals that the foam sandwich structure formed under the 0.15 MPa bonding process outperforms the rest regarding static properties. These findings provide valuable insights into the optimal structure-forming process for PMI foam sandwiches, paving the way for future advancements in th

In this work, three different types of sandwich structures were manufactured, each using a Formica sheet (a paper-based sheet) as the skin and perlite/sodium silicate foam as the core, with or without a paper honeycomb. The sandwich structures were fabricated by attaching the Formica sheets on both sides of a paper honeycomb core panel, a perlite/sodium silicate foam core panel, and a perlite/sodium silicate foam-filled honeycomb core panel. The flexural characteristics were studied by a three-point bending test and the thermal conductivity was measured using Lee’s thermal conductivity apparat

Résumé :

A honeycomb structure is a sandwich structure widely used in fuselage, among which the hexagonal honeycomb core is the most widely used. The energy absorption characteristics and impedance ability of the structure are the main reasons that directly affect the energy absorption characteristics of the honeycomb sandwich structure. Therefore, it is necessary to study the out-of-plane mechanical properties of the composite honeycomb sandwich structure. Based on the numerical simulation results, the energy absorption characteristics of several composite honeycomb sandwich structures are verified by

Résumé :

Vibration transmissibility is an important factor to characterize the vibration absorption performance of cushioning packaging materials during transportation. Reasonable prediction of vibration transmissibility can guide antivibration design and reduce packaging cost. As a kind of green cushioning material, paper honeycomb sandwich structure is widely used in transport packaging because of its good machinability. But at the same time, it also has strong water absorption capacity. To a great extent, the vibration transmissibility of paper honeycomb sandwich structure may be affected by ambient

Résumé :

Polymer foam cored sandwich structures are frequently exposed to elevated temperatures in the range of 50-100°C. Recent theoretical studies showed that elevated temperatures may shift the behaviour of sandwich structures from linear and stable to nonlinear and unstable. Although this prediction has not been experimentally validated, it has aroused concerns on the performance of sandwich structures at elevated temperatures. Thereby, a focused experimental study is required to confirm the thermomechanical interaction effects. The work described in this thesis provides experimental assessments on

This paper studies large sample classical and Bayesian inference in a prototypical linear DSGE model and demonstrates that inference on the structural parameters based on a Gaussian likelihood is unaffected by departures from Gaussianity of the structural shocks.

The underlying reason for the cancellation is the certainty equivalence property of the linear rational expectation model. The main implication of this r

Résumé :

Steel girder ends are susceptible to corrosion damage due to deicing salts, water, and other contaminants leaking from failed expansion joints. When corrosion becomes significant, it leads to a reduction in the sectional properties of steel girders and consequently reduces bearing and shear resistance. Conventional repair methods, although effective, require substantial time and resources to complete, causing public inconvenience from necessary traffic closures. Therefore, there is a need for practical, rapid, and robust repair methods suitable for implementation by local Department of Transpo

STUDY ON FLEXURAL CAPACITY OF PROFILED STEEL SHEET - POLYURETHANE SANDWICH SLABS. The Hong Kong Institute of Steel Construction, 2024. http://dx.doi.org/10.18057/ijasc.2024.20.1.6.

Résumé :

Widely employed in enveloped structures, the metal-faced sandwich panel boasts thermal insulation, noise abatement, lightweight, and remarkable assembly efficiency. In this paper, a new type of profiled steel sheet and polyurethane sandwich slab (PSSPSS) was proposed. Through static load tests and numerical simulations, the flexural properties of the PSSPSS were studied, and the influence of individual geometric parameters on the flexural capacity of the structure was evaluated. The results of this analysis led to the derivation of the calculation formulas for the deflection and flexural beari

LOCAL BUCKLING (WRINKLING) OF PROFILED METAL-FACED INSULATING SANDWICH PANELS – A PARAMETRIC STUDY. The Hong Kong Institute of Steel Construction, 2022. http://dx.doi.org/10.18057/icass2020.p.248.

Texte intégral

Résumé :

This study aims to investigate the effects of various parameters including the height of the profiling region, spacing of profiling ribs, length of the panel, thickness and modulus of the foam core, and thickness of the profiled face sheet, on the local buckling capacity of profiled metal faced insulating sandwich panels. A simplified finite element (FE) modeling approach that models the profiled face sheet as a folded plate structure resting on elastic foundation is adopted. This modeling approach was validated through comparison with tests results and 3D FE modeling of the entire sandwich st

NUMERICAL STUDY ON SHEAR BEHAVIOUR OF ENHANCED C-CHANNELS IN STEEL-UHPC-STEEL SANDWICH STRUCTURES. The Hong Kong Institute of Steel Construction, 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.4.

Texte intégral

Résumé :

This paper firstly developed a three-dimensional (3D) finite element model (FEM) for enhanced C-channels (ECs) in steel-UHPC-steel sandwich structures (SUSSSs). The FEM was validated by 12 push-out tests on ECs with UHPC. With the validated FEM, this paper performed in-depth parametric studies on shear behaviours of ECs with ultra-high performance concrete (UHPC). These investigated parameters included bolt-hole gap (a), grade (M) and diameter (d) of bolt, core strength (fc), length of C-channel (Lc), and prestressing force ratio on bolt (ρ) in ECs. Under shear forces, the ECs in UHPC exhibite
