Investigation of thermal properties of Al1050/SS304 sandwich composite sheet by using a numerical, analytical and experimental approach

The effect of geometrical and process parameters on the deep drawing behavior of Aluminium (Al1050)/Steel (SS304) bimetallic axis-symmetric sandwich composite cup is analyzed by using numerical and experimental approaches. The parameters are selected focusing on the elimination of defects like thinning, thickening, tearing, and wrinkling. The explicit deep drawing analysis of the cylindrical cup is carried out by using the finite element software package. The obtained numerical results are utilized for the optimization and identification of significantly influencing parameters using Taguchi and ANOVA techniques and further validated by performing an experimental test. The effectiveness in the utilization of the Al1050/SS304 sandwich composite sheet for deep drawing of cups is proved by comparing it with the deep drawing of the SS304 sheet. The results suggest that the sandwich composite cup under investigation can be drawn successfully with the higher limiting drawing ratio and low thickness variation. The obtained maximum limiting drawing ratio (2.08) showed that the higher formability of the Al1050/SS304 sandwich composite sheet is possible by a sandwich of the SS304 sheet with an Al1050 sheet.

“…Apart from excellent strength-to-weight ratios, MPM SMs also have an advantage in terms of thermal insulation. With a proper selection of core material and its thickness, the thermal insulation of MPM SMs can be significantly improved [4,18,64,65]. The heat flow through an MPM SM cross-section can be seen in Figure 6.…”

“…This advantage has been significantly used in the aerospace industry, as MPM SMs have been used in several components of space vehicles to provide thermal protection [67]. In a recent study, the thermal conductivity of the SS304 steel-Bakelite (Al1050) SMs was investigated [64]. A tremendous decrease in thermal conductivity was found for the SS304-Al1050 SMs.…”

The demand for innovative materials has been a significant driving force in material development in a variety of industries, including automotive, structural, and biomedical. Even though a tremendous amount of research has already been conducted on metallic, polymeric, and ceramic materials, they all have distinct drawbacks when used as mono-materials. This gave rise to the development of nature-inspired sandwich-structured composite materials. The combination of strong metallic skins with soft polymeric cores provides several advantages over mono-materials in terms of weight, damping, and mechanical property tuning. With this in mind, this review focuses on the various aspects of MPM SMs (Metal/polymer/metal Sandwich Materials). The reasons for the improved qualities of MPM SMs have been discussed, as well as the numerous approaches to producing such SMs. This review shows the various possibilities of achieving such SMs in complicated forms via different shaping techniques and intends to highlight the properties of MPM SMs’ remarkable qualities, the current trend in this field, and their potential to meet the demands of many industries.

Conceptualisation of design and development of modular and customised ration storage system for Army rations sustainable up to -40°C was carried out. The Indian Armed Forces operate under various climatic conditions, which are inhospitable for cooking, storing fresh/perishable food products and carrying rations for their survival during an emergency. Hence, there was an ever-existent demand for a customised, user-friendly ration storage system. Considering a number of user-friendly features, a system has been designed comprising modular unit structures with insulated wall panels containing Polyurethane foam (PUF) sandwiched between metallic and composite material claddings. An insulated structure is required to maintain the temperature at high altitudes during extreme low-temperature conditions. The temperature and humidity are regulated and maintained using solar panels and humidly modulators. The modular structure with individual temperature and humidity control is suitable for the safe storage and preservation of fresh produce, fruits and vegetables, and milk and animal products. In case of perishable commodities of Defense supplies inclusive of leafy and tender vegetables, juicy fresh fruits, egg, chocolates, meat carcasses stored in silo are safe as its insulated structure ensures no freezing even upto -25° Celsius hence protects them from quality damage due to subzero temperature exposure and abuse. Therefore, the normal convention of the expected shelf life for each such commodity was extended approximately double the normal shelf life expected. An extensive design process involving CAD modelling followed by mechanical load simulation and analysis resulted in a robust and capable system. Each compartmentalised segment caters for an average one-ton material depending on the nature of the material. The system is suitable to store 3 tons of ration at a time to address the requirement of 100 individuals for 60 days in monsoon cut off and peak winter cut-off posts. Total energy consumption under fully load condition is approx. 2KW to maintain peak temperature gradient of 45-50°C.The outer surface of the structure can be camouflaged. The well-insulated structure ensures zero leakage and is sturdy to withstand a wind velocity of 60 km per hour and a standing snow load of 2 meters above it.
