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 32.2-38.7o). 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.
