Influence of Ion-Beam Carbon-Fiber Surface Treatment on the Angle of Wetting by Epoxy Oligomers

The influence of the regimes of modification of carbon fibers by an argon ion beam on the change in the angle of their wetting by an epoxydiane oligomer has been investigated.

Description
Summary:The influence of the regimes of modification of carbon fibers by an argon ion beam on the change in the angle of their wetting by an epoxydiane oligomer has been investigated. It has been shown that ion-beam treatment of carbon fibers leads to a considerable decrease in the wetting angles (the difference between the wetting angles for nonmodified and modified fibers is up to 32.2-38.7°). Accordingly, there is also an increase in the value of the equilibrium work of adhesion by 36.2-41.6% in the contact zone. It has been established that ion-beam treatment of carbon fibers by argon ions leads to an increase in the shear strength when microplastics based on them are formed.[PUBLICATION ABSTRACT]
