APPLICATION OF ADHESIVES AND PLASMA MODIFICATION TO INCREASE THE ADHESIVE STRENGTH OF FIBROUS COMPOSITES

Abstract

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.
