Honeycomb Sandwich panel

Honeycomb panel sandwiches or natural structures made from a honeycomb geometry that allows the amount of material to be used to achieve the minimum weight and minimum material cost. The sandwich geometry of the honeycomb panel varies widely. But the common aspect of all these structures is the array of hollow cells between the thin, vertical walls. The cells are often columnar and hexagonal.

Sandwich honeycomb panels are used in the airline industry and other industrial applications. Sandwich honeycomb panels consist of thin shells with inner and outer plates. The Honeycomb Sandwich Core is configured to link the first and second shells. This panel may in general be called a sandwich panel, and the purpose of this invention is the plate structure that reinforces the panel, and so that the shell and core are separate.

A major example of this invention is the strengthening of honeycomb panels on the aircraft. In the structure of the aircraft jet engine, this panel is used to reduce engine noise. When the force above, the extreme temperature difference, vibration, the skin of the honeycomb panel may be separated from the core, which may result in a deliberate nuclear missile failure.

The strength and strength of composite materials depends on two factors:

Outer shell

Interface between core and skin

Honeycomb sandwich structure

Honeycomb structure is widely used in sandwich panels, this type of panel can be used in a variety of types, including FRP sandwich panel, aluminum composite panel, etc. Sandwich panel honeycomb made of polyester reinforced with plastic, fiber High strength and glass are made. On the anti-slip floors, the pattern of the tread is obtained through a constant process of vacuum absorption and agglutination and freezing.

Honeycomb Sandwich Panels Production Plan

  1. Product Specifications

Sandwich panels are referred to as composite structures, which consist of a relatively weak central core and strong external layers. Generally, sandwich panels are installed with glass fiber (fiberglass) or natural fiber composites. A sandwich panel is actually composed of two main parts: first the middle core is relatively weak and usually bulky. The other is the shells on both sides of the core that are strong and thin. Typically, the middle weak core is made of foam or nude, and the shells located on either side of the core are made of glass fiber composites, natural fibers and metals. This seemingly simplistic structure offers great advantages and abilities. A sandwich structure has a much higher resistance to its single components, and has an extraordinary style. It also has a relatively low cost and can be used quickly and easily in construction. Sandwich panels are the most commonly used composites in the building industry after palletogene profiles and open-molded products. Although these panels were formerly made available through the Chinese manual layout and open mold technique, today, thanks to machining processes, the speed and quality of these products have grown tremendously. This has led to a reduction in the cost and increased popularity of these products.

Major Consumption of Sandwich Panels:

The competitive advantage of production:

The set of all the reasons for the general failure of the industry of sandwich panels in the country can be summarized in the low level of technology of domestic production units. The growth of Iran’s population and the increase in the need for housing and living space has led to an increase in demand for fewer, faster and cheaper construction. The prevalence of partitions, ceilings, and walls of Kazab during the past few years has confirmed this allegation. Over the past years, activities have been undertaken by some small and large companies to make Sandwich Panels. Sandwich panels produced in this institute consist of a foam core and reinforced concrete layers. (Reference: Analytical Paper on Sandwich Panels in Iran and the World of Technology Analysts Network). The structure of the kiosk walls is, in fact, a sandwich structure with a honeycomb-like core and fiberglass layers. Some cases of fiberglass application in the construction of false walls and ceilings produced by small workshops can also be seen on the market.

Nonetheless, as it was said, the low level of technology that production at low and slow levels, the drop in the quality and the lack of uniformity of products, and ultimately the high cost of production and hence the high cost of these products, are not responsive to the growing demand of the domestic market and The use of new technology and mechanized production lines with the capability to produce the best product quality is the most important advantage of industrial sandwich panel production in Iran.

The growth of population and the significant volume of demand growth in the housing sector and the rapid adoption of the use of partitions and pendant composite ceilings instead of their gypsum on the one hand, and the lack of uniformity of domestic products of sandwich panels and composites due to low quality and high cost for the consumer ( Of course, for the manufacturer, given the handicap and the use of very low production technologies in major workshops) and the distribution of production in the form of small workshops, the orientation towards investing in the production of sandwich panels at an industrial scale in the shadow of the use of new technology Investing higher than the new topology that capital The high cost of production in the small and scattered units in the country has proven this fact. The project has now been successfully implemented and its technical knowledge is available.

 

Fiber-reinforced plastic composite (FRP) deck is increasingly being used in highway bridges, both in new construction and in the rebuilding and replacing of existing bridge decks. Recent applications have shown that FRP honeycomb panels can be used efficiently and economically for highway block systems. This article, by designing the design and experimental features of a FRP honeycomb panel, has a sinusoidal atomic geometry in the plane and a vertical extension of the face sheets. Honeycomb structure analysis and components including: sticky material and properties, face lamination and core wall building properties, equivalent minerals properties, and apparent hardness properties for the honeycomb panel and its equivalent orthodontic properties. A homogenization process is used to obtain the equivalent properties of nuclear material for honeycomb geometry with sinusoidal waves. To examine the accuracy of the analytical solution, several honeycomb sandwiches are tested with sinusoidal waves or in longitudinal or transverse directions in bending. Also, a deck panel has been tested under both symmetric and asymmetric patch loading. Limited Numerical Modeling (FE) test specimens are used using more layered elements for the correlation of results with analytical predictions and empirical values. A summary of the use and use of the FRP honeycomb panel for bridges is summarized. A simple, simple analysis method can be used to design and optimize honeycomb structures efficiently.
