INSTALLATION FOR FORMING PRODUCTS FROM POLYMER COMPOSITE MATERIALS BY vacuum infusion

摘要

The invention relates to mechanical engineering, namely, to installations for the formation of products from polymeric composite materials (PCM) vacuum infusion method, and can be used in the aerospace, automotive, shipbuilding and other industries. Apparatus for molding articles of composite polymeric material comprises vacuum infusion in the form of snap placed on the support structure forms a molding surface for laying the reinforcing preform material. Above the display with Laid it preform assembled technological package including a layer of sacrificial fabric, the top of which is placed a distributor grid with an overhead supply line of the polymeric binder, which is covered with two layers of vacuum film to sealingly connect to the molding surface of the tooling means located along the perimeter of the sealing plaits . Vacuum line for the pumping of air technology package, connected to a vacuum pump, a vacuum is made in the form of a groove which is formed in the molding surface of the mold tooling on its perimeter with the inner side of the sealing plaits, and which is stacked metal chain. Thus, the above-described apparatus for forming products from composite vacuum infusion method will simplify installation for molding of the FRP product by vacuum infusion and its assembly as well as reducing its cost. 1-yl.
