FIELD: production processes. ^ SUBSTANCE: proposed invention covers the method of producing sandwich material for aircraft fuselage panels. The sandwich panel consists of a pack of alternating layers of the material and binder courses of plastic material. The first row of layers is laid into the mold, one above the other. Then, at least, one the second row of layers is laid on the first one to make a pack of layers. Note here that, at least, one row of layers is displaced, in a reverse-step manner, relative to the first row layers on edge of the pack. Nearby the aforesaid displaced layer, an auxiliary tool is arranged to make a gap between the former and auxiliary tool side facing it. Now, the temperature and pressure onto the pack are increased to allow binder mold flow in the plastic binder courses and accumulation of a certain amount of binder from the aforesaid reverse-step layer in the gap. The invention covers also the aircraft fuselage sandwich panel produced by above described method. ^ EFFECT: smooth joint of sandwich panels. ^ 5 cl, 8 dwg |
