Abstract
Работа посвящена анализу деформационного поведения фторопласта в условиях нагружения и изучению возможности изготовления фторопластовых изделий методом холодного формоизменения прессованных заготовок без последующих операций нагрева и термофиксации размеров готовой детали. На основании многочисленных исследований, проводимых по изучению полимера в различных лабораториях, авторами предпринята попытка создания механической модели фторопласта и обоснования возможности применения к расчету фторопластовых изделий теоретических методов и подходов, разработанных для низкомолекулярных материалов.
Abstract in another language
The work is devoted to the analysis of deformation behavior of fluoroplastic in the conditions of loading and to studying of possibility of manufacturing of fluoroplastic products by a method of cold forming of the pressed preparations without the subsequent operations of heating and thermofixing of the sizes of a ready detail. On the basis of the numerous researches of the polymer in various laboratories, authors undertake attempt of creation of mechanical model of fluoroplastic and substantiation of possibility of application of theoretical methods and the approaches, developed for low-molecular materials, to calculation of fluoroplastic products. A technological process of manufacturing of cutting fluoroplastic rings obtained by winding a tape preparation on cylindrical pilot is considered, and possibility of creation a theoretical base for design and calculation of a tool allowing cold deformation to obtain a product of demanded shape and size is studied. By results of the analysis it is established, that owing to high crystallinity of fluoroplastic, obtained at polymerization and increasing at recrystallization processes, its structure can be considered as completely crystal, homogeneous and isotropic, corresponding to materials studied in the mechanic of solid deformable bodies.
