FIELD: construction.
SUBSTANCE: method includes manufacturing of nonoriented polymer film from fluoroplastic-4 or fluoroplastic composition, filling specified film into cells of mesh in the form of strip by means of film rolling on rolls from two sides with production of sheet stocks. Afterwards sheet stocks are assembled into a packet fixed in frames, and sheet stocks in packet are sintered at the temperature of 643-653 K under pressure generated by fluoroplastic expansion, and packet is disassembled.
EFFECT: simplified technological process, expansion of produced goods assortment and improved technical properties of material.
