Application of Adhesives and Plasma Modification to Increase the Adhesive Strength of Fibrous Composites

Abstract

It is shown that the use of amino aldehyde oligomers as an adhesive in fibrous composite materials based on synthetic fibers leads to an increase in the adhesive interaction between components. Due to the limited wettability of the synthetic fiber filler with adhesives, it is advisable to carry out preliminary RF plasma treatment of fibers in a plasma-forming air medium. The matrix polymer and the adhesive have good mutual adhesion, and the lack of adhesion between the adhesive and the synthetic fibers is compensated by the formation of functional reactive groups on the surface of the synthetic fibers during RF plasma treatment.

Simulation of the processes of plasma modification and vacuum metallization of polymer materials by the method of molecular dynamics

“…Vacuum-plasma methods are promising methods for modifying and functionalizing the surface of synthetic polymeric materials. RF plasma modification makes it possible to control such surface properties of synthetic polymeric materials as roughness, wettability, and adhesion, while not leading to the destruction of surface layers and deterioration of the physical and mechanical properties of materials [1][2][3][4][5][6]. The use of the magnetron sputtering method makes it possible to deposit metal and metal-containing coatings of high uniformity on polymer materials of various structures and fibrous composition, and the method is characterized by high productivity and the absence of a destructive effect on the surface of polymer materials [7].…”
