Abstract
The analysis of prospects of development space-rocket hardware technicians speaks about increase in a share of polymeric composite materials in designs of flying machines. But their manufacture is connected with certain expenses of energy. And it puts forward a problem of working out of new technologies of reception of products from polymeric composite materials on time reduction solidification polymeric binding without decrease in quality polymeric composite materials. Wide application space-rocket hardware technicians have found fibreglasses in products on a basis epoxy binding and fibrous filler (fabrics, fibres, plaits). For experimental working off of technological process solidification polymeric composite materials on samples the microwave, as a source of electromagnetic radiation of ultrahigh frequency has been chosen. Researches spent at different values of capacity on an exit of a microwave and heating time. Influence electromagnetic field the microwave oven on process solidification thermosetting polymers leads to creation of more sewed and more ordered structures that promotes increase of physicomechanical properties of a material. Studying of structural changes in polymers spent a method X-ray. In work supervised volume shrinkage hydrostatic weighing binding by a method. The received results have allowed to choose the optimal mode solidification binding under the influence of electromagnetic field the microwave oven whom the microwave oven to temperature 130°С in a current of 14 minutes with the subsequent free cooling in the furnace to temperature 60° and after that - consists in heating electromagnetic field at the open furnace - cooling to room temperature. This mode provides fuller solidification compositions (degree solidification - 97,5 %) after comparison with convection a method.
