Claims (2)

1. Способ изготовления изделий из композиционных материалов, включающий нанесение пропитанного связующим исходного материала на жесткую оправку, размещение оправки в гидроклаве, вакуумирование пакета материала на оправке при помощи эластичной диафрагмы и отверждение под воздействием давления и температуры, отличающийся тем, что сначала холодный пакет исходного материала нагружают давлением 45-48 кгс/см2, затем после выдержки в течение 15-20 мин и сброса давления нагревают пакет до температуры 50-60°С, нагружают горячий пакет давлением 37-47 кгс/см2, продолжают нагрев, выдерживают пакет при температуре 150-160°С в течение 8 ч, охлаждают пакет до температуры 50-60°С, сбрасывают давление и продолжают охлаждение, при этом нагрев пакета перед выдержкой и охлаждение после выдержки производят со скоростью не более 15°С в час, причем перед охлаждением вакуум снимают.1. A method of manufacturing products from composite materials, comprising applying a binder-impregnated starting material to a rigid mandrel, placing the mandrel in a hydroclave, evacuating the material bag on the mandrel using an elastic diaphragm and curing under the influence of pressure and temperature, characterized in that the cold source material is initially cold load pressure of 45-48 kgf / cm 2, then after aging for 15-20 minutes, and the pressure relief package is heated to a temperature of 50-60 ° C, hot pack loaded pressure to 37-47 s / cm 2, heating was continued, the package is maintained at a temperature of 150-160 ° C for 8 hours, cooled to a temperature packet 50-60 ° C, depressurized and the cooling is continued, with the package heating before exposure and after exposure to produce cooling with at a rate of not more than 15 ° C per hour, and before cooling, the vacuum is removed. 2. Способ по п.1, отличающийся тем, что вакуум создают не менее 0,6 кгс/см2.2. The method according to claim 1, characterized in that the vacuum create at least 0.6 kgf / cm 2 .
