Abstract

Polymer composite materials are gradually replacing metals, including in such important structures as an aircraft wing or a fuselage. One of the technological stages in the manufacture of blanks for future parts is the process of laying out the prepreg on the tooling. When laying out, the stickiness of the prepreg plays an important role. The stickiness of the prepreg to the substrate should be such that it does not separate from it during transportation and is easily separated when moving onto the tooling. An analysis of the stickiness level depending on temperature, compaction force, and the speed of separation from the substrate is given in this article.
