Wall Panels

The production process and application of large composite external wall panels (composite panels for short) are introduced in this paper. Composite panels with both load bearing and thermal insulation were formed by pouring normal concrete (NC) and ceramsite foamed concrete (CFC) continuously according to particular technological requirements, which made two layers into a seamless whole. The layers of NC and CFC are for load bearing and thermal insulation respectively. The composite panels were manufactured in the scale of industrial production, and applied to several energy saving prefabricated buildings successively, instead of polystyrene sandwich composite panels (sandwich panel for short) as external wall panels. There are several obvious advantages of the composite panel over the sandwich panel or outer benzoic board. Firstly, it solved the problems of durability of polystyrene and the complex production process of the sandwich pane, the production process of the external wall was thus greatly simplified. In addition, the fire risk was much reduced.

Hydrodynamic Impact

The float and hull are vital parts of amphibious planes and boats, respectively, as both have to absorb hydrodynamic impact due to interaction with water. Sandwich composite panels are commonly used for such applications and other impact-absorbing structures. Unfortunately, the failure mechanism of sandwich composite panels under hydrodynamic impact is very complicated, as it may consist of composite skin failure, core failure, and non-uniform delamination. Hence, a numerical study on the damage of sandwich composite panels under hydrodynamic load is necessary. In this study, numerical simulation implementing the Coupled Eulerian-Lagrangian (CEL) method was performed to observe the damage mechanism of sandwich composite panels. The CEL method combines the Lagrangian and Eulerian frames into one model. Thus, analysis of structure deformation and fluid motion can be performed simultaneously. The result of the current numerical simulation shows a fair agreement with the experimental results in the literature, which shows that the current methodology can represent the sandwich composite panel response in real-life conditions, especially before shear core failure initiates.

In recent years, with the continuous development of society, people's awareness of energy conservation has also been enhanced. Among them, building energy consumption occupies a very large proportion in all their energy consumption. Therefore, people have taken various measures to reduce the energy consumption of building its own. External wall thermal insulation is a new building energy saving technology. Through verification, application of external wall insulation technology in building energy saving greatly reduces the energy consumption of buildings. This paper mainly introduced on the city building external wall thermal insulation technology and some related measures.

Optimum Insulation Thickness

In Turkey, “Thermal Insulation Requirements for Buildings” was implemented to provide energy saving in buildings in 2000. After this, more then seven hundred thousand new buildings are constructed. Determining the correct material and optimum insulation thickness are very important issues in these buildings for thermal insulation. Calculations using monthly outdoor temperatures and solar radiation are done for XPS insulation material and 4 different climatic regions in Turkey. Natural gas, the most preferred in our country is selected as fuel. P1-P2 method is used to obtain energy saving and payback period. New correlations are specified to determine optimum insulation thickness depending on building heat gains and areas. Furthermore, buildings are categorized into three building class according to external wall area and floor/roof area. Effect of change in building external wall area, floor or roof area, window area to payback period, energy saving and optimum thickness are investigated. As a result, effect of architectural design is determined on thermal insulation. All calculation results are shown in a table for four different climatic regions and three different types of buildings which have the same gross volume.

The development of composite materials from alternative raw materials, and the design of their properties for the intended purpose is an integral part of the rational management of raw materials and waste recycling. The submitted paper comprehensively assesses the physical and mechanical properties of sandwich composite material made from particles of winter rapeseed stalks, geopolymer and reinforcing basalt lattices. The developed composite panel is designed for use as a filler in constructions (building or building joinery). The observed properties were: bending characteristics, internal bonding, thermal conductivity coefficient and combustion characteristics. The results showed that the density of the particleboard has a significant effect on the resulting mechanical properties of the entire sandwich panel. On the contrary, the density of the second layer of the sandwich panel, geopolymer, did not have the same influence on its mechanical properties as the density of the particleboard. The basalt fibre reinforcement lattice positively affected the mechanical properties of sandwich composites only if it was sufficiently embedded in the structure of the particle board. All of the manufactured sandwich composites resisted flame for more than 13 min and the fire resistance was positively affected by the density of the geopolymer layer.
