Title Technology of polytetrafluoroethylene-based nanocomposite materials: Structural and morphological aspect
Author Victor Voropaev
Abstract We conducted complex researches of the characteristics of formation of a heterophase structure in the polytetrafluoroethylene (PTFE) based composite materials containing fillers and modifiers of different composition and geometry habit at concentrations of 20-35 wt%. Also, the directions of improvement of manufacturing process of the products with increased parameters of strength and tribological characteristics consisting in the control of the structure composites at various levels are defined. The mode of modifying action of thermogasdynamic synthesis products of polytetrafluoroethylene in a composite is established. We developed the technology of modification of carbon fibers with ultrafine particles of products of the thermogasdynamic synthesis (UPTFE) for PTFE-based composites, which provides wear resistance increase by 1,1-1,2 times and strengths by 1,1-1,35 times when forming products by cold pressing with the subsequent agglomeration.
