The invention relates to the field of structural panels, and in particular to a lightweight sandwich panels containing foamed polymeric filler. The results of the development can be used as part of a special constructions of aircraft-and shipbuilding, the manufacture of sports training equipment, large collapsible layouts.
Famous sandwich panel with a polymeric binder containing alternating layers of impregnated fiberglass and bars foam, playing the role of a placeholder. After laying the components of the blanks panel is formed by applying a pressing and induction heating (patent RF №2381132). When sufficient complexity of manufacturing the panel does not meet certain requirements, because the foam easily and irreversibly deformed as from chemical and thermal effects. This may be compromised the integrity of the panel and lost some of the initial specified property.
Famous sandwich panel (PM No. 80874), consisting of upper and lower casings and cell glued filler, combined with additional foam filler. The manufacture of the panel is time-consuming. If this panel does not have near the required physical and mechanical properties or stability of these properties in terms of external influences.
Famous sandwich panel (PM No. 105326), the soda is containing the upper and lower casing, between which is mounted on the glue filler. The filler is made of reinforced discrete gas-filled plastic. Increasing the strength of the filler discrete elements are located in the most loaded areas. They have the configuration of the stiffeners. On a number of essential features of the sandwich panel by GR No. 105326 as the closest to the claimed panel adopted as a prototype. Main achieved by the patent of the prototype is reducing the complexity. Reducing the complexity reached by the introduction of discrete elements in the loaded areas of the fill. Used gas-filled plastics based on polystyrene, polyvinyl chloride, polyurethane, phenolic, epoxy, carbamid and silicone resins. The authors of the utility model is recommended to produce gas-filled plastic layer coating composition. However, in the text there is no indication on the modes and conditions of deposition. It is not clear how made themselves discrete elements as required localization chopped fibers, wire, metal, polymer and ceramic particles in the conditions of sputtering gas-filled plastic is problematic. This applies in particular to a vertically positioned regions 7, marked on figure 5 description of the prototype. Thus shatrugna the analysis of allegiance approval of reducing the complexity of the manufacturing panel, how about the main achievable result. In some cases this method of application seems to be difficult and there is little compatible with the installation of discrete elements. If the discrete elements set in advance, how to produce fastening the top and bottom panels on glue? Some technical issues associated with the method of fastening the top panel after filling the rest of the volume.
The whole design of the prototype seems to be working, but practically difficult. However, in the description GR No. 105326 almost do not provide specific data about the operations of the execution of discrete elements in the manufacture of sandwich panels.
The main technical task of the present application is related to design efficient in operation and technologically feasible sandwich panels.
Another technical challenge is the development of a method of manufacturing the panel.
Technical problem in the design of the panel is solved due to the fact that reinforced discrete elements contain shaped shell of appropriate dimensions, geometric configuration, arrangement and composition, and on the inside of the shells is a composite material with the desired combination of properties.
The technical problem according to the method is solved by the fact that when the bottom is th plating on it mounted on the adhesive layer pre-formed shaped shell of discrete elements, filled composite material with the desired content of discrete reinforcing elements, then make the filling the rest of the structural volume of gas-filled plastic, mechanical surface treatment and installation of the upper shell.
To achieve the result is a clear localization of reinforced discrete elements within the required geometrical dimensions, configuration, strength characteristics. This makes it possible to ensure that the composition and structure of three-layer panels structural calculations. Depending on the specified configuration shaped shells of discrete elements they can be produced by the methods of pneumaturia and vacuum molding of thermoplastics, technology blown polymers, installation on melted and soluble models.
The design of the inventive panel is illustrated in figure 1, figure 2, figure 5. The inventive method of manufacturing a panel is illustrated in figure 3, figure 4.
