Abstract:

The stretched-membrane concept has the potential for reducing the cost of heliostats used for solar thermal energy generation in central receiver systems. In this concept, a high strength/structural membrane carrying the reflective film is stretched uniformly on a toroidal frame. The resulting structure has high stiffness and is structurally efficient. It is practically suitable for composite materials, since the loading is primarily in-plane. In this paper, the application of composite materials to stretched-membrane heliostat design is investigated. The results of the analysis show that comp

Abstract:

A composite material is generally a combination of materials differing in composition or form on a macro scale for the purposes of attaining specific characteristics and properties. The developments in the field of composite materials have granted significant weight reduction in structural design. When compared to metallic materials, composites offer many advantages, especially high strength, stiffness to weight ratio, excellent fatigue properties, and corrosion resistance. Plates, curved panels, the cylindrical shell-shaped forms of models are being broadly used in many structural packages of

Abstract:

Peritectic compound Li4(OH)3Br has been recently proposed as phase change material (PCM) for thermal energy storage (TES) applications at approx. 300 °C Compared to competitor PCM materials (e.g., sodium nitrate), the main assets of this compound are high volumetric latent heat storage capacity (>140 kWh/m3) and very low volume changes (<3%) during peritectic reaction and melting. The objective of the present work was to find proper supporting materials able to shape stabilize Li4(OH)3Br during the formation of the melt and after its complete melting, avoiding any leakage and thus obtain

Abstract Introduction. This article offers a methodology for the analysis of a two-layer composite beam on an elastic foundation that represents a one-parameter Winkler model. The behaviour of two-layer beams is described by A.R. Rzhanitsyn in his theory of composite rods that have rigid transverse and elastic-yielding longitudinal connections between layers. The theory of composite rods allows to study the stress-strain state (SSS) of multilayer foundation beams, having a layer featuring low thermal conductivity, and perforated beams. Materials and methods.

Purpose The purpose of this paper is to fabricate and characterize the natural fibre (NF) reinforced epoxy composites containing flame retardants (FRs) and microcrystalline cellulose (MCC) in terms of flammability, thermal properties and dynamic mechanical performances. Design/methodology/approach The FRs used in this study were ammonium polyphosphate and alumina trihydrate. Findings The results demonstrated that the addition of MCC particles into the flame retardant composite (control) further enhanced the self-extinguishing properties of composites, in particular, the burn length.

Abstract:

A reliability analysis of silver diamond composites in terms of both thermal and mechanical properties is presented. This new material is an attractive solution for power electronics packaging, because an improvement of 50% in terms of thermal management and channel temperature can be obtained when using silver diamond composites as a base plate in packages compared with the more traditionally used materials such as CuW. However, to date, little is known about the reliability of this new material, such as changes induced in its properties by thermal cycling. Assessment of the reliability of si

The use of sustainable hybrid components is an important topic in lightweight automotive applications. Wood being a renewable material, when used in combination with other materials such as technical polymers, offers a high potential for producing hybrid components and the implementation of innovative lightweight automotive materials. The feasibility of wood-based hybrid automotive components strongly depends on the properties of the interface between wood, lignin as a renewable coupling agent, and technical polymers.

The acoustic radiation responses of laminated sandwich baffled flat panels subjected to harmonic loading in an elevated thermal environment are investigated via a novel coupled finite and boundary elements formulation based on the higher-order shear deformation shell theory. The structural stiffness and mass tensors are obtained using competent finite element steps engaging the Hamilton’s principle followed by computation of acoustic responses by resolving the Helmholtz partial differential equation. An in-house MATLAB code is developed based on the present formulation for the computation of a
