Beschreibung
Zusammenfassung:	FIELD: production of complex shape constructional organosilicon pieces for radio industry. SUBSTANCE: impregnation of reinforcing filler with resin and its thermal treatment under temperature of 180 - 200 C is exercised by melt of hydroxyl-bearing polymethylsiloxane resin, that has 3 - 6 % flying substances and under temperature of 120 C viscosity of 0.2 - 0.6 Pa.s and duration of viscous-flow state for 100 - 200 minutes. Resin is heated together with form, that has preliminary placed reinforming filler, up to 120 - 150 C temperature under pressure of 2 - 4 atmospheres and vacuum of 0.7 - 0.9 atmosphere with following thermal treatment of form with filler. EFFECT: production of large-size complex form organosilicon pieces with increased density. 1 tbl Сущность изобретения: пропитка армирующего наполнителя смолой и термообработка при 180 - 20С, пропитку осуществляют расплавом гидроксилсодержащей 3 - 6% летучих веществ, имеющей при температуре 120С, вязкость 0,2 - 0,8 Па с и время вязко-текучего состояния 100 - 200 мин, нагретой вместе с формой, содержащей предварительно уложенный армирующий наполнитель: до температуры 120 - 150С под давлением 2 - 4 атм и вакуумом 0,7 - 0,9 атм с последующей термообработкой формы с изделием. 1 табл.
