Abstract

In this review, the stickiness property of prepregs is considered, which affects the technological parameters in the process of laying out the workpiece parts from polymer composite materials. Various methods for determining stickiness, advantages and disadvantages of these methods are considered. It is shown that stickiness of prepregs depends on the temperature and storage conditions of prepregs. Dependence of the stickiness of prepregs on the temperature makes it possible to ensure easy separation of the prepreg from the substrate and to pass through the belt tape at a reduced temperature without adhering to the rollers, and then good adhesion to the tooling and to the prepreg layers due to heating to the temperature of high tackiness. The material VKU-25 developed in VIAM will allow to carry out the automated technology at manufacturing of preparations of details from polymeric composite materials.
