| description | The invention relates to laminated hybrid alumopolymer materials comprising alternating sheets of aluminium alloys and layers of reinforced polymer composite material, such laminated materials are intended for use as structural sheet material for loaded parts of airframe (skins, partitions, stringers of fuselage and wings, floor panels, etc.) and for the repair thereof, and also for surface transport parts. There is suggested the composite laminated material comprising the alternating Al sheets and layers of glass fibre-reinforced plastic including the thermosetting binder and reinforcing filler, said composite material is characterized in that the aluminium sheets comprise at least two layers, one of which is made of high-modular Al-Li alloy of reduced density with Li content of more than 1.5%, and the other one is made of the alloy of Al-Mg-Si system, with layers' thicknesses ratio being (70-12):1. In the composite material the layer of Al-Mg-Si alloy appears to be outer with respect to the composite material and has the ultimate strength not less than 260 MPa, yield strength not less than 220 MPa, elongation not less than 10% and stationary electrochemical potential not less than 20 mV more negative than that of Al-Li alloy. The article fabricated from said composite material is also suggested. The technical result is the invented laminated composite material having the improved properties of technological plasticity in the course of shaping process of the articles, and the corrosion resistance, and also other high service characteristics. |
